Title:
SENSORLESS DETECTION METHOD OF ROTOR POSITION
Document Type and Number:
Japanese Patent JP2006129667
Kind Code:
A
Abstract:
To provide a sensorless detection method of rotor position in which the conduction sound of a current is reduced without lowering detection precision.
The sensorless detection method of rotor position for detecting the rotor position of a single motor M being driven or regenerated by a first inverter 3 and a second inverter 4 comprises a step for conducting a current i to the first inverter 3 out of the first inverter 3 and the second inverter 4 and detecting the rotor position from the combined inductance of the motor M which varies with the current i.
