Switched Reluctance Motor

SWITCHED RELUCTANCE MOTOR

INTRODUCTION

Switched reluctance motor (SRM) is electromagnetic and electrodynamics equipment which converts the electrical energy into mechanical energy. The electromagnetic torque is produced on variable reluctance principle. SRM makes use of

^v   Power semiconductor switching circuitry and

^v   Rotor position sensor.

SRM is singly excited and doubly salient electrical motor. This means that it has salient poles on both the rotor and the stator but the only one member carries winding. The rotor has no winding, magnets and cage winding but it is build from a stack of salient pole laminations.

^v   Its construction is simple and robust

^v   It requires less maintenance

^v   Its overall efficiency is better

^v   It is flexible control driving motor as motoring mode generating mode of operations of the machine can be easily achieved,

In the light of above it is a competitive motor variable speed dc motor and variable speed 3 – phase cage induction motor.
