Abstract:

The switched reluctance motor is a new variable-speedmotor system,The basic control strategy for a switched reluctance motor is explained in this paper. Its operating performance is based on the ability to provide each phase with oulses of current during torque productive periods of rotation and to adjust their amplitude either by chopping or by selecting predetermined switching angles. A microprocessor controller is also discussed in the paper.The angle controller is designed using dedicated digital hardware, whereas the functions are implemented using an Intel 8031 single-chip microcomputer.The complete controller is tested in the laboratory with a 500w prototype, and the test results are found to be excellent.

Key words: switch reluctance motor, motor control, microprocessor systems
