Supply, converter connection, armature voltage and smoothing reactor
The rated voltages specified in the selection tables are standard voltages in accordance with DIN 40030.
The ratings at these rated voltages are only valid in conjunction with the specified converter connection and supply voltage.
All inductance values specified in the "Selection and Ordering Data" tables of Catalog DA 12 · 2004 are at 100 Hz, for single-phase and at 300 Hz, for three-phase bridge circuits.

Non-standard voltages and converter connections
The standard ratings specified on the rating plate should –whenever possible - be kept, even if the motor characteristics deviate from the rated values in the selection tables, because the rating plate data, with these rated values, is part of the order number. Non-standard rating plate data would require the short code Y80 for "Non-standard rating plate data" (refer to Catalog DA 12 · 2004, chapter 3 "Selection and Ordering – Options").
If the rated DC voltage of the converter selected has to be lower than the rated armature voltage specified in the selection tables, with the converter connection and system voltage rating remaining unchanged to accommodate higher AC supply voltages, the motor speed and output can be obtained by changing the rated motor values in the same ratio as the voltages. If a smoothing reactor is required according to the selection table, this must be used even at lower voltages. Operation with other converter connections available on request.
Converter operation
For motor operation with converters the controller has to be set up optimally before starting the operation. The dynamic of the controller should be chosen as low as possible in order to spare the mechanical system of the drive train. An automatic speed controller optimization run requires a connected driven machine. The resulting settings have to be checked and to undergo a plausibility check.
Optimization runs don`t always produce good results for each application case. Therefore the controller adjustments have to be checked by means of adequate tools (oscilloscope, etc.).
In certain cases a manual postoptimization might be necessary.
The operation manual of the converter has to be observed.
Smoothing reactor
For motors of frame sizes 100 to 160 for operation with converters with a half-controlled or fully-controlled single-phase bridge circuit (B2H or B2C) the machine can be utilized more favourably, if a series inductance is provided. The recommended values are specified in Catalog DA 12 · 2004, chapter 3 "Selection and Ordering".
The total inductanceLa +Lv as specified in the tables can be reduced for:
- converter operation from a lower supply voltage in the ratio of the voltage reduction (e.g. at 320 V instead of 380 V, down to 84 %)
- unchanged supply voltage and a 60 Hz supply frequency instead of 50 Hz, down to 83 %
- lower output (on request) down toLv = 0.
For motors with very small armature circuit inductances, i.e. balanced motors and motors with high output (referring to the frame size), the use of a smoothing reactor can reduce the current ripple and thereby also the torque and the speed ripple, as well as the commutation stress. This leads to extended brush downtimes.
Speed and speed control
DC motors are operated within the armature control range until they reach the rated speednn. In this case the motor speedn is approximately proportional to the armature voltageV. Furthermore the machine can be operated by field weakening, i.e. by reducing the field current to the maximum field weakening speednFmax, respectively to the mechanic speed limitnmech.
The speed-output diagram shows the relation between VoltageV, CurrentI, OutputP, TorqueM and Speedn.

The series inductance and noise can increase in the speed range fromnFmax tonmech (further details are available on request).
For uncompensated motors, field weakening ranges exceeding 1:1.2 are only permissible if stable operation is ensured using speed control. Motors which are not controlled must be equipped with a series stabilizing winding to ensure stable operation (please inquire).
Speed increase by field weakening is also possible from any speed within the armature control range, The ratio for loading with the rated current must be
Field weakening speed / Speed at full field ? nFmax /nn

If the motor speeds deviate from the specifications in Catalog DA 12 · 2004, chapter 3 "Selection and Ordering", e.g. as a result of
- speed adaption using armature voltage change and/or field weakening
- further defined, permissible field weakening speeds (without short code or with short codes C05 and C06) which are not available for standard versions
the short code Y80 (non-standard rating plate data) and plain text will also be required when ordering (refer to Catalog DA 12 · 2004, chapter 3 "Selection and Ordering – Options").
Direction of rotation
Motors are designed for both clockwise and counter-clockwise directions of rotation or reversing operation. When ordering, it is only necessary to specify the direction of rotation for motors of frame size 500 and 630 (counter-clockwise rotation: K98, or both directions of rotation: K99).
Output and overload capacity
The rated outputs specified in the selection tables are referred to continuous running duty S1 in accordance with DIN EN 60034-1 for converter operation with the rated armature voltage and the assigned converter connections and supply voltages (refer to section "Supply, converter connection, armature voltage and smoothing reactor", page 10) using, if required, the series inductance specified in the selection tables.
For self-ventilated motors with an armature control range of 1:3 and decreasing load torque, an approximate linear interpolation can be made between the rated torque and the torque at the lower limit of the armature control range over the speed.
The permissible output and the associated speed for other ambient conditions can be seen in diagrams under “Other operating and ambient conditions“.
Overloading of the motors is possible in accordance with the following table.

Protective field winding shunt resistor
If the motor field winding is supplied from a separate voltage source (always required for armature control), a shunt resistor should be provided for protection against overvoltages produced as a result of self-induction at switch-off. The same applies to motors with a common supply for the armature and field circuits when the field winding is disconnected from the armature when the motor is shut down. The protective shunt resistor is not included in the scope of supply of the motor.
The approximate resistor size can be seen in the table on the right. Intermediate values may be interpolated linearly.

The shunt resistor specified in the table above is dimensioned in accordance with the permissible voltage stressing in the motor. If field reversal is used, it may be necessary to limit the voltage to a lower value in view of the voltage limit specified for the field rectifier.
If other components are used instead of protective shunt resistors, for example such as varistors or overvoltage arrestors (refer to fig. right), these should be selected in accordance with the following criteria.
