Title: Current detector of induction motor
Inventor: IMAI HIROSHI
IPC: G01R19/04
Filed: 1996-02-08
Abstract: PROBLEM TO BE SOLVED: To enable an effective value and torque current to be detected by detection of instantaneous current of a phase by obtaining phase difference between a phase of an effective value of a voltage instruction of a phase corresponding to current obtained from a voltage instruction part of an inverter and a rectangular wave obtained by a current zero-cross detection circuit and calculating by using a specific formula.
