Benshaw Wound Rotor Motor Starters
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 electro-mechanical starter on the stator, and introduce multiple stages of resistance in the rotor via a contactor arrangement to achieve a soft ramp.
With the RediStart MX2/MX3, wound rotor control is greatly simplified. The RediStart consists of two main major sections:
- A solid-state stator control, and
- Secondary resistors into the rotor circuit from a separate 3-phase resistor bank.
This design achieves the high torque required by the application, with low inrush, while providing a smooth stepless start … greatly reducing the maintenance cost of the typical electro-mechanical control.
