Use of variable frequency drives with wound rotor motors

The slip ring or wound rotor induction motor (WRIM) has been used in a variety of applications. Many of these applications use the WRIM’s high starting torque capability while limiting current to start and run very high inertia loads such as hammer mills, rolling mills, centrifuges, and rotary kilns. Other applications utilize the variable speed capability of the WRIM. Probably the

What is a Wound Rotor Motor and How Does it Work?

22/10/2021 In wound rotor motors, the rotor is “wound” with wire similar to the stator, with their terminal ends connected to 3 slip rings on the output shaft. These slip rings are attached to brushes and variable power resistor banks, where operators can change the speed of the motor by varying the resistance through the rotor coils. These slip rings allow for speed and torque control and are the

Medium Voltage VSDs in mill drive applications

drive them. The electrical component, ie electric motors, has tradition-ally been large wound rotor induction motors which are commonly known as slipring motors. In order to start these motors with the correct amount of torque requires a certain amount of resistance on the rotor which is generally provided by making use of a LRS. This delivers the required start up and running torque while
