Title: Leak inductance measuring instrument for induction motor
Inventor: KAIDA HIDETOSHI
IPC: G01R27/26
Filed: 1989-01-10
Abstract: PURPOSE:To take a measurement without reference to the operation state of the induction motor and to enable full automatic measuring operation wherein a rotor need not be restrained by identifying leak inductance by using a high frequency component generated by a power converter. CONSTITUTION:The impedance of the leak inductance in a high frequency range is large, so a voltage applied to the resistance of a high frequency equivalent circuit is slight and 90 deg. delayed in phase. For the purpose, the output of an oscillator 34 which generates a sine wave of frequency which is much lower than a PWM frequency is applied to L'' and modulated and then an effective value detector 35 generates a signal in phase with the oscillator output when a set value is larger than an actual value and an opposite-phase signal when the set value is smaller, but the frequency component of the oscillator is zero when the set value is equal to the actual value. A signal of the same frequency component with this oscillator is detected by a synchronous detector 36 and L is adjusted by a parameter adjuster 37, so that the value of L can be identified.
