Designed for applications requiring constant closing torque, the RG Series synchronous motors come in sizes of 35, 50, and 64 and operate at 50 and 60 Hz. The torque-limited devices feature a magnetic ...

A synchronous and synchronous motors are the two main categories of ac motors. The induction motor is a common form of asynchronous motor and is basically an ac transformer with a rotating secondary.

Industrial applications use direct current motors because the speed-torque relationship can be varied to almost any useful form -- for both motor and regeneration applications in either direction of ...
