Device and method for detecting rotor speed of a multiple phase motor with bipolar drive |
摘要 |
A method for detecting rotation of a rotor of a multiple phase motor with bipolar drive is described, excluding a three-phase motor with bipolar drive with star connected coils or motor stator windings. The motor has at least a first and a second energizable motor stator winding. A voltage is sequentially and alternately sensed on the first and the second motor stator winding at or near the end of a period of a non-energised state thereof. An apparatus for detecting rotor speed is also provided.
