1)DC motors of frame size 355 to 630 are offered in the catalog only in the IMB3 type of construction.

2)For type of construction IMB5 the motors are supplied in IMB35, for IMV1 in IMV15 and for IMV3 in IMV35.
1HQ and 1HS motors are only available in type of construction IMB3 and IMB35.

3) For these types of construction, special support feet must be provided for relieving the strain on the fixing bolts in the transverse direction (from frame size 180 upwards).

Cooling type, degree of protection

The cooling types of the motors are in accordance with DINEN60034-6 or IEC60034-6, the degrees of protection in accordance with DINEN60034-5 or IEC60034?5.

For an overview of the cooling types and degrees of protection for standard DC motors refer to section "Overview of cooling types and degrees of protection", page 6.

The degree of protection symbols for motors and terminal boxes specified in the catalog consist of 2 code letters and 2 code digits. These are described below:

IP:International Protection: Code letters designating the degree of protection against contact with live or moving parts inside the enclosure and the ingress of solid bodies and water.

1st digit:Degree of protection against contact with Iive and moving parts and the ingress of solid bodies.

2nd digit:Degree of protection against the ingress of water.

Note:

The higher the 1st and 2nd digit, the higher the degree of protection.

For vertical types of construction the degree of protection IP23 is only granted, if the air inlet point shows downwards.

The short codes for the cooling types of the motors specified in the catalog consist of 2 letters (IC = International Cooling) and a combination of digits and letters. Further details can be found in DINEN60034-6.

Cooling,airflowdirection

The cooling air is normally fed from commutator end (non-drive end NDE) to the output end (drive end DE), where it discharges through shutter openings or gill-type plates to the left and right. The motor output is reduced by approximately 12% for motors of frame size up to 160 if one side of the air outlet has to be blocked, the out put is only reduced by 6% if the duct is on one side (no shutter ribs in this case).

Arrangement of the air inlet or outlet openings on DE and NDE:

Frame size

Air intake and discharge opening on

100to160(1G.5)

2x: on the side, right and left

160to200(1G.6)

3x: on the right, left and top

225to630

on all 4 sides


The air flow direction can be changed from the drive end to the non-drive end for 1GG and 1GH motors, short code K64 (refer to Catalog DA122004, chapter 3 "Selection and Ordering - Options". De-rating may be necessary in certain cases (refer to the table below).

In many application fields, but especially when machines are operated with weak loading, low cooling air inlet temperature or under difficult ambient conditions, it is recommended to ventilate the machine from DE to NDE.

Refer to Catalog DA122004, chapter 3 "Selection and Ordering - Options" for possible duct connections for 1GH motors.

Air-to-water and air-to-air coolers

Motors with air-to-water cooler (1HS) are ventilated by means of a fan unit with a three-phase motor mounted in the cooler assembly. The heated internal air is recooled via a water cooler. With a cooling water inlet temperature of 25C 1HS motors have the same output as 1GH motors.

The standard water connections (as viewed from the drive end) are located on the right. For 1HS6186 to 288 and 1HS7351 to 455 a subsequent changeover of the cooler for water connections on the left is only possible for special design water coolers.

Motors 1HS5500 to 635 are equipped with coolers with removable water boxes. In this case a later relocation of the cooler is also possible.

Normal cooling water temperature rise up to 10K, water pressure up to 6 bar (test pressure 9bar).

If you feel uncertain about the required cooling types, please inquire a cooler with water analysis.

Standard version:

Coolers with copper tubes and copper collectors (not removable) for non-aggressive water which has been cleaned to remove any solid particles. Vibration stress up to 0.6g (63Hz).

Special design (short code M10):

Coolers with CuNi10Fe tubes, CuZn38SnAl tube sheets and removable plastic-coated steel chambers for water with a pH value of between 5 and 9 and a maximum chloride content of 25g/l.

The cooling tubes can be cleaned mechanically.

Motors of frame size 250 to 630 can be provided with a filter in the internal air circuit.

Motors with air-to-air cooler (1HQ) are ventilated by means of two fan units with a three-phase motor mounted in the cooler assembly. The recooling of the heated internal air takes place via an air-/air-heat exchanger. The fan unit for the internal air circuit is mounted axially, the fan unit for the external air circuit is mounted on top of the cooler. 1HQ motors have an output of approximately 70% of 1GH motors.

Fan units

1GF, 1GG, 1HQ and 1HS motors have built-on fan units with three-phase motor, supply voltage 380 to 420VAC, 50Hz or 380 to 500V.

For operation at 60Hz with motors from frame size 250, a plain text indication in the order is necessary.

The specific data of fan motors can be taken from the following tables.

Filter and silencer mounting

Air filter

If the installation place of the motors supplies only cooling air with unsufficient percentage of purity, the mounting of a filter is necessary.

If in the case of very high percentage of dust at the location of use the effect of the filter is not sufficient or if the maintenance intervals for the filters are too short, it is recommended to use a surface-cooled motor in degree of protection IP54 or a with a duct connection separately cooled motor of the 1GH type in degree of protection IP54/IC37.

A dry-type filter can be mounted on all 1GF and 1GG motors (refer to Catalog DA122004, chapter 3 "Selection and ordering - Options"). The filter is mounted axially in front of the fan intake.

Filters can also be retrofitted. Derating is not required.

The filtration efficiency is 99% for a dust particle size of 10m. The efficiency decreases for smaller particle sizes.

The noise levels are reduced by 1 to 2dB for motor frame sizes from 160 to 280 if a filter is mounted.

Silencer

For 1GG motors from frame size 180 a silencer can be mounted on the air inlet of the separate fan. Thereby the sound pressure levelLpA of the 1GG motors can be reduced by approximately 5dB.

The mounting of a silencer is also possible in combination with an air filter.

Noise levels

The sound-pressure levelsLpA and the sound power levelLWA (including tolerance) specified in the table below apply at full load up to 2000RPM for B6C converter connection and standard separate fan unit at 50Hz

The values forLpA andLWA are significantly lower than the values permitted in accordance with EN60034-9.

The sound power levelLWA is the sum of the measuring-surface level and measuring-surface sound-pressure levelLpA.

A motor noise no-load/load differential of 3 to 5dB can be assumed when making comparisons with the standard. The no-load noise levels, when fed from pure DC, are approximately 3dB below the noise values for converter supply.

When using a silencer the specified noise levels can be reduced by approx. 5dB.

Bearings

Motors up to and including frame size 200 have pre-lubricated rolling contact bearings. Larger motors have regreasable rolling contact bearings.

The original grease charge of the pre-lubricated bearings normally lasts for two years, after which time it must be replaced.

Motors with regreasable bearings can be re-lubricated while the motor is running.

For extreme conditions, e.g. high cooling temperatures (exceeding 60C), motors, frame sizes 112 to 200, normally fitted with pre-lubricated bearings, can be supplied with regreasable bearings (refer to Catalog DA122004, chapter 3 "Selection and Ordering - Options").

A locating bearing is used at the drive end and a floating bearing at the non-drive end of motors up to frame size 132. For motors, frame size 180 and upwards, the non-drive end has a locating bearing and the drive end a floating bearing.

1G.5/1H.5 motors, frame size 160, are fitted with a locating bearing at the drive end, 1G.6 motors, frame size 160, at the non-drive end.

Depending on the degree of protection or the arrangement of the bearings, the bearings are sealed using grease-packed grooves and/or axial shaft sealing rings or INA ring disks or sealing disks (RS bearings) preventing the ingress of dust.

For motors, frame size up to 280, the bearings can accept the weight of the rotor including that of the coupling half if the motor is mounted in an inclined or vertical position.

Please inquire if the motor is to be subject to higher axial loading and for motors with frame size from 355 upwards.

Refer to the table below for the bearing assignments.

The bearing assignments are valid for motors with all types of construction and vibration severity grades N and R.

Permissible cantilever forces

When using power transmission elements, which result in cantilever forces of the shaft end (belt drive or direct mounting on gears), it has to be taken care that the limits specified in the cantilever force diagrams aren`t exceeded. Possibly it is necessary to use a cylindrical roller bearing at the drive end (short code K20, refer to Catalog DA122004, chapter 3 "Selection and Ordering - Options").

The permissible cantilever forces for motors, frame size up to 450 are specified in the following cantilever force diagrams. For motors with frame size 355 to 450 it is assumed that no cantilever forces appear, as the output takes place via a coupling. In this case cantilever force diagrams only exist for bearing increased cantilever forces.

The cantilever force diagrams are only applicable for standard drive shaft ends. The permissible cantilever forces for non-drive shaft ends and non-standard drive shaft ends the permissible cantilever forces must be determined for each particular case (please inquire).

The dimension x specified in the cantilever force diagrams is the distance between the line of action of the force FQ and the shaft shoulder. The dimension xmax corresponds to the length l of the shaft end.

The permissible cantilever forces for radial loading at the drive shaft end are specified in the following cantilever force diagrams (based on a normal bearing service life of 20 000 hours)

Mechanical performance, vibrations

All motors are equipped with low-noise and low-vibration rolling-contact bearings. All of the motors in Catalog DA122004 fulfill vibration severity grade N.

Refer to the table below for recommended maximum vibration severity grades for electric motors in accordance with DINEN60034-14 (up to 3600RPM) and factory specifications.

There are no design restrictions for vibration severity grade R.

For flange-mounted motors, frame sizes 100 to 160 with vibration severity grades S, the reduced tolerances for the mounting flange (permissible positional variances for the shaft end) are maintained in accordance with DIN42955. If these reduced tolerances are also to be maintained for flange-mounted motors, vibration severity grade R, these motors must be ordered with high-precision flanges grade R in accordance with DIN42955.

From frame size 180 the vibration severity grade S is only practicable with deep groove ball bearing at the drive end and with horizontal foot-mounted types. From frame size 355 vibration severity grade S on request.

Permissible vibration levels from external sources

The system vibration characteristics as a result of the mechanical drive output elements, alignment and mounting, as well as the influence of external vibrations can result in higher motor vibration values. The motor vibration values specified in the table below should not be exceeded with a view to perfect commutation, low brush wear and long bearing service life.

In certain cases, it may be necessary to completely balance the motor with the mechanical output drive elements.

Balancing

The rotors of 1G.5/1H.5 and 1G.6/1H.6 motors are dynamically balanced with complete fitted key (full-key balancing).

The rotors of 1G.7/1H.7 motors are balanced with half key (half-key balancing).

This should be taken into account when balancing the drive elements.

Foundation

The systems engineer has to assure a resonance-free mounting of the motor.

For the design of the foundation DIN4024, part2 has to be observed.

Terminal boxes

All motors have a terminal box for connecting the main DC supply. As standard for all motors the terminal box is mounted on the right side when viewing on the drive side shaft end. If required, it can also be located on top (except for motors with top-mounted coolers) or on the left-hand side. For horizontal types of construction and terminal boxes on the right, the cable entry is at the bottom. The terminal box can be subsequently rotated through 90. All terminal boxes have degree of protection IP55.

DC terminals

The terminal box (refer to table below) has 2 field winding terminals and 2 armature terminals as well as additional terminals for PTC thermistor sensors, space heaters or similar.

Labelled terminals are available for connecting the protective conductor. For motors, frame size from 180 upwards (and 1G.616.), an additional external protective conductor on the outer side of the motor is available (for cross-sections refer to table "Conductor sizes and cable entries).

Main supply conductors

The dimensions of the main supply conductors have to be in accordance with DINVDE 0298. The amount of the necessary parallel supplies is determined by

  • the maximal connectable conductor cross section
  • the cable type
  • the cable laying
  • the ambient temperature and
  • the permissible current in accordance with DINVDE 0298.

Cable entries

Depending on the motor size various terminal box versions are used. Terminal boxes with cable entry drillings are closed by sealing plugs.

Terminal boxes of larger motors have a cable entry plate which is normally supplied undrilled. It can be unscrewed from the terminal box for drilling (for details refer to table "Conductor sizes and cable entries).

Terminal designations of DC motors

The terminal designation of DC motors is in accordance with DINEN60034-8.

For fixing the rotational direction in relation to the armature current and the field direction, applies the rule that on operation of a DC motor in clockwise rotation the polarity of currents L+ and L- corresponds to the polarity of connections A1 and A2, as well as to connections F1 and F2.

For counter-clockwise direction the polarity of the supplies has to be changed either to the armature or the excitation field.
