Abstract
Since rotor position information is necessary to drive the SRM, absolute-encoder, resolver and incremental-encoder is used to detect a rotor position. But, it is not desirable to use a high priced encoder and high efficient microprocessor under the condition of the simple driving system when precision control is not demanded. In this paper, Only using the reflective type 2 photosensors replace the conventional opt interrupter and slotted disk, which not only remove a slotted disk section but drive 3-phase 6/4 SRM bidirectionally. Moreover, as control circuit only is composed of common analog device, economy is maximized.
