Overview
SIMOTICS M-1PH8 motors are compact permanent-magnet
synchronous motors with IP55/IP65 degree of protection. The
motors are available in different cooling types:
•
Forced ventilation for SH 132 to SH 225
•
Water cooling for SH 132 to SH 225
The motors have been designed specifically for use in conjunc-
tion with the SINAMICS S120 drive system. Depending on the
control requirements, appropriate encoder systems are avail-
able for the motors for sensing the motor speed and indirect
position.
