摘要: Stator slots are skewed relative to rotor slots with a skew amount comprising an integer multiple of a stator electrical angle of 60.degree., thereby minimizing a torque ripple which is an integer multiple of six times of a primary frequency of electrical energy.

摘要: An induction motor control apparatus includes a detector, a memory, a correction current generator, and a primary current correction circuit. The detector detects a rotational position of a rotary magnetic flux generated by a multi-phase primary current applied to a primary winding of an induction motor. The memory stores correction values corresponding to measured values of torque ripples periodically generated in correspondence with the rotational positions of the magnetic flux, receives an output from the detector for detecting the rotational position of the magnetic flux, and outputs one of the correction values stored in the memory in correspondence with the rotational position. The correction current generator generates a correction current by the correction value read out from the memory in correspondence with the rotational position of the magnetic flux. The primary current correction circuit corrects the primary current by the correction current.
