motor life is ensured with the use of external resistor banks or liquid rheostats that dissipate heat buildup generated during motor startup. What makes the wound rotor motor a unique induction machine is its rotor. Instead of a series of rotor bars, a set of insulated rotor .
Wound rotor motors are typically used in application requiring high starting torques, a limited number of operating speeds, or a stepped acceleration to achieve a soft start. Typically, existing applications utilize an electromechanical starter on the stator, and introduce multiple stages of resistance in the rotor via a contactor arrangement ...

A woundrotor motor is a type of induction motor where the rotor windings are connected through slip rings to external resistance. Adjusting the resistance allows control of the speed/torque characteristic of the motor. Woundrotor motors can be started with low inrush current, by inserting high resistance into the rotor circuit; as the motor accelerates, the resistance can be decreased.
Feb 07, 2008· vfd on slip ring "wound rotor" motors posted in Variable Speed Drives: I am involved in converting a ball mill, which requires a large amount of starting torque, from a slip ring motor driven application to a vfd driven appl. . We have sent the motor to our motor guy to refurbish and interconnect the rotor there any advice or ...
Common types of grinding mills include Ball Mills and Rod Mills. This includes all rotating mills with heavy grinding media loads. This article focuses on ball and rod mills excluding SAG and AG mills. Although their concepts are very similar, they are not discussed here. Photographs of a glass ended laboratory ball mill show action of ball mass within the mill.

Motors considered are the squirrel cage motor, wound rotor motor, and synchronous motor. One important advantage of the synchronous motor is the possible correcting of power factor within your operation, through its use. When using a synchronous motor we recommend having 200% starting torque, 120% to 130% pullin torque, and 225% pullout torque.

A phase wound rotor of three phase induction motor is also called slip ring rotor and the motors employing this type of rotor are known as phase wound or slip ring induction motors. Slip ring rotor consists of a laminated cylindrical core having semiclosed slots at the outer periphery and carries a 3phase insulated winding.
Sep 18, 2011· We operate ball mills with dualcoupled 3500hp 4160v wound rotor induction motors. We have recently experienced frequent arcing of the slip rings which seems to start on the center ring. The arcing damages the ring badly which requires us to shutdown the mill to sand it smooth again.
system, couple the motor to the mill. Another possibility is to use a motor that can develop sufficient torque such as the wound rotor induction motor with rotor resistor starter. There are some drawbacks to be considered while using such a fix speed direct on line alternative independently if a high – or low speed solution is selected.

Froment''s "mouse mill" motor was an early form of electric motor, also known as the Revolving Armature Engine. It has similarities to both the synchronous motor and the contemporary stepper motor.. As the mouse mill motor was simple to construct and its speed could easily be governed, it was later used to drive automatic recorders in telegraphy.
