摘要： PROBLEM TO BE SOLVED: To provide a motor control apparatus capable of restoring a magnetized state even if a permanent magnet is unintentionally demagnetized during an operation of a motor. SOLUTION: When a demagnetization detection unit 58 detects that an alnico magnet is demagnetized from the magnetized state during the operation of the motor 1, a magnetization control unit 59 restores magnetic force by increasing magnetization again of the alnico magnet. The demagnetization detection unit 58 compares an induced voltage command Eq_ref with induced voltage Eq detected by an induced voltage detection unit 56 when an induced voltage command decision unit 57 decides an induced voltage command in accordance with an operation state of the motor 1. When the latter is lower than the former by a prescribed rate or a prescribed value, demagnetization of the alnico magnet 9b is detected. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To efficiently and surely eliminate an unbalanced state in a rotating drum.
SOLUTION: In this drum type washing machine, an unbalanced state in the rotating drum is recognized based from the rotation variation of a motor in a process wherein the revolution number of the motor is raised to a maximum revolution number at the time of a dehydrating operation, and a cloth loosening control in response to the unbalanced state is performed. For example, when it is judged that an unbalance occurs in the right and left sections in the rotating drum, the driving of the motor is stopped for one time, and then, the motor is rotated for 5 seconds at a low speed so that the revolution number of the rotating drum may become approximate 50 rpm. When it is judged that an unbalance occurs at around the center of the rotating drum, the driving of the motor is stopped for one time, and then, the motor is rotated for 20 seconds at the low speed so that the revolution number of the rotating drum may become approximate 50 rpm.
