Stepper Motors 
CT Series Step Motors
Run cooler, produce more torque, and support higher shaft loads than any other step motor.
The CT series motors combine innovative cooling technology, high torque magnetic designs, rugged bearings, and high voltage insulation systems.
The motors are availyble in a viariety of lengths, windings and shafts.
Flange, connection and winding can be modified upon request.
