Introduction to MKE digital AC motors

1.1 General 

features

In conjunction with digital intelligent INDRAMAT drive controllers, MKE
digital AC motors create cost-effective drive systems with a broad range
of functionalities for use in potentially explosive areas.

Motors with the following continuous standstill torques and nominal
speeds are available:
