■
Overview
SIMOTICS M-1PH8 motors are compact asynchronous
squirrel-cage motors with IP55/IP65 degree of protection.
SIMOTICS M-1PH8 motors are available in two different
cooling types:
•
Forced ventilation
•
Water cooling
The motors have been designed specifically for use in
conjunction with the SINAMICS S120 drive system. Depending
on the control requirements, appropriate encoder systems are
available for the motors for sensing the motor speed and indirect
position.
For machine tools, the encoder system is capable of C-axis
operation as standard – i.e. an additional encoder is not required
for C-axis operation.

With applications in which extreme ambient conditions, such
as high temperatures, dust, dirt, or a corrosive atmosphere, do
not permit air cooling
7
In processes in which the environment must not be heated
