Review on switched reluctance motor control system

Switched reluctance motor speed control system is composed of switched reluctance motor, the power converter, the control device, angular displacement sensor with five parts installed in the drive circuit of a new type of electromechanical integration control device. Its efficiency in a wide range of speed regulation can be greater than 87%. The motor structure is unique, there is no winding of the rotor or stator permanent magnet as the concentrated winding, easy to install. Its winding end short and strong, than the system of DC motor, synchronous motor and induction motor are simple, manufacture and main-tenance is very convenient. At the same time, the switched reluctance motor control convenient, can run for four quadrant, has a simple structure, small size, light quality, reliable work, easy to control, the advantages of its performance and economic indicators is superior to the ordinary asynchronous motor speed control system.
