Third-party motors that can be operated
You can also operate the following non-Siemens motors with the SINAMICS G115D wall-
mounted converter:
• Standard asynchronous (geared) motors
• Most permanent magnet synchronous motors designed for converter operation with
moderate saturation:
– Surface-mounted permanent magnet synchronous motors
– Integrated permanent magnet synchronous motors
Restrictions for permanent magnet synchronous motors:
• Continuous operation of a permanent magnet synchronous motor at speeds < 15% of the
rated speed is not possible.
• The load moment of inertia should be more than 20% of the motor moment of inertia.
• Cogging torque < 4% of the rated torque
• Sinusoidal EMF generator voltage with THD ≤ 2%
• EMF generator voltage ≤ rated voltage of the converter
• Rated motor voltage ≤ 0.9 mains voltage
Multi-motor operation
Multi-motor operation involves simultaneously operating several motors from one converter.
For standard asynchronous motors, multi-motor operation is generally permissible.
Additional preconditions and restrictions relating to multi-motor operation are available on
the Internet:
