| Abstract |
Although it has been known since 1838, the switched-reluctance motor has gained little acceptance in high volume markets, despite its potentially lower cost and superior performances. This is mainly due to its reputation of requiring expensive and complicated control circuitry. This paper shows an attempt to reduce the number of components and sensors needed to control a switched reluctance motor, in the case of a low speed drive with regular torque requirement, such as a fan drive. The full schematic is given, along with test results. We then expand the concept to the general case (any speed, any torque) by showing the questions which should be asked before starting a design, and give general rules to find the answers. |
