Title:
MOTOR DRIVE DEVICE
Document Type and Number:
Japanese Patent JP2013192396
Kind Code:
A
Abstract:
To provide a reliable motor drive device capable of appropriately controlling a speed of a motor without influence of variation of an inductance of the motor.
A value of an inductance of a motor is selected within a pre-stored selection range. The selected value of the inductance is used for estimation of a rotor speed, and the value of the inductance is sequentially searched and amended within the selection range to reduce a difference between an estimated rotor speed and a target speed.
