  • Entry
  • Associated product(s)


This application only applies to MICROMASTER 4 with Firmware < V4.0



The compact 1PH7 induction motors are so-called frameless motors. These were originally developed and adapted for use with the SIMODRIVE and MASTERDRIVES drive inverter systems. 1PH7 motors are exclusively four-pole motors. The rated speed is changed via the winding. When certain prerequisites are fulfilled, 1PH7 motors can also be fed from MICROMASTER MM440 drive inverters. Engineering information/instructions, selection criteria and parameterization of the drive inverter for this mode are provided in this description.
