Title:
【発明の名称】シャフト位置センサ無しでの切替式反作用モーターの回転子位置感知
Document Type and Number:
Japanese Patent JPH08501920
Kind Code:
A
Abstract:
Apparatus and method for detecting rotor (12) position in a switched reluctance motor (18) having multiple stator phases (A-A', B-B', and C-C'). A multiplexer (48) intermittently connects a known resistor (54) to a non-conducting stator phase. Circuitry (62 and 68) detects the amplitude of the current passing through the resistor (54) and the phase difference between the varying voltage and the current passing through resistor (54). The resulting signal is proportional to the position of rotor (12).
