How Eddy Current Changes Pump Speed Without Changing the Motor Speed
dynamatic2022-06-21T16:22:42-05:00By DSI/Dynamatic, Inc. An Eddy Current Drive uses eddy currents - loops of electrical current created by changing the strength of a magnetic field. As the drum turns and excitation current is applied, a torque is developed, and the output rotor drives the load. In an Eddy Current Drive, the motor and driven equipment are not physically connected. The Eddy Current Drive goes between the motor and pump and the input and output shafts turn independently. This allows for the motor to always be running at design speed, providing maximum cooling to the motor helping extend the motor life and the ability [...]
