【発明の名称】誘導電動機の制御装置
Document Type and Number:
Japanese Patent JP2677494
Kind Code:
B2
Abstract:
A control circuit for an induction motor calculates the d-axis current and q-axis current of a rotor in the motor and estimates the variation of the flux and resistance of the rotor on the basis of the d-q axis currents. As a result, a three-phase current for compensating for the resistance of the rotor varied due to the temperature and environment is suitably controlled to obtain high-performance of the motor.
