Properties

Overview
The AC motors in the 1PH4 series are compact, water-cooled squirrel-cage induction motors
with a high degree of protection.
They have been designed specifically for use in conjunction with the SINAMICS S120 drive
system, allowing power losses and noise levels to be reduced to a minimum. Depending on
the control requirements, the appropriate encoder systems are available for the motors.
These encoders are used to sense the motor speed and indirect position.
In 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.
