SIMOTICS FD

Motors of the SIMOTICS FD series are designed for a wide range of different applications. For outdoor use, special applications or specific boundary conditions, an inquiry must be made to establish whether a catalog version is suitable or a special version is recommended. This is particularly the case with:

• Applications with increased mechanical stress due to vibration or shocks
• Installation on deck (ships)
• Frame sizes V15, V5 and V6
• Piston engines, hackers, crushers, shredders, shearing machines
• Deviating rated motor voltages, speeds or outputs

Structure of catalog motor selection tables

The SIMOTICS FD motors have been optimized for operation with converters of the SINAMICS range. The selection tables are therefore structured as follows:

1. Motor type – cooling method (1LM1, 1LL1, 1LH1, …)

2. Line voltage/frequency (400 V, 50 Hz; 460 V, 60 Hz; …)

3. Type of infeed (regulated or unregulated)

4. Rated speed (1500 rpm, 1800 rpm, …)

In the selection tables, a SINAMICS converter is also recommended for each motor. The motor data is specified for operation on this converter, or on another converter that is comparable with regard to the output voltage (section "Voltage supply").

Ambient conditions and site altitude

The output data specified in the catalog is applicable to ambient temperatures of -20 to 40 °C and site altitudes of up to 1000 m above sea level. For ambient conditions outside this range, derating is necessary.

For water-cooled motors, the data specified in the catalog is based on a coolant inflow temperature of 25 °C, whereby derating is necessary for a coolant temperature of 25 °C and a site altitude of > 1000 m.
Deviating installation conditions can be clarified on request.

Duty types

The operating data specified in the catalog for SIMOTICS FD motors is applicable to duty type S1 (continuous duty according to DIN EN 60034-1). Overloading is possible in the case of duty types S2 (short-time duty), S3 (intermittent periodic duty) and S6 (continuous operation periodic duty). The applicable overload factors can be taken from the tables below for these three duty types.

The overload factors are valid on starting when the motor is cold and when the resulting torque is less than or equal to the maximum overload torque (T_B). If the motor is prewarmed due to recent operation or it is in a thermal steady-state due to continuous duty (S1), thermal class 155 (F) will be exceeded under overload conditions. Depending on the amount of overload, the maximum winding temperature can be exceeded and the motor can be damaged.

With 1LQ1, 1LP1, 1LH1 and 1LN1, it is not permitted for the cooling to be interrupted.
