Abstract
New detection of the rotor information of squirrel-cage induction moto rs for a stable torque control is carried out by using a highly sensit ive Magneto-Impedance micro magnetic sensor. A magnetic field detected near an edge of the rotor shaft is estimated to be proportional to th e rotor current with a slip frequency (psf/2) and a torque when the mo tor is driven with a constant V/f inverter, A stable control for the s tationary torque is realized independently of the motor temperature va riation.
