摘要
A device and method to estimate the resistance of a stator winding of an AC induction motor is provided. The device includes an AC induction circuit connecting one phase of the AC induction motor to an AC source. The circuit includes a resistor and a switch connected in parallel. The switch is alternatively closed during the half cycles of the AC current supplied to the motor so as to inject a DC voltage and current bias to the AC motor. The resistance of the stator winding is estimated in response to the DC voltage and current bias.
