摘要:
A motor having a structure capable of achieving a reduction in magnetic flux leakage occurring at a rotor and a washing machine, to which the motor is applied. The motor includes a stator including a plurality of stator cores arranged in a circumferential direction, and coils respectively wound around the stator cores, and a rotor rotatably arranged inside the stator. The rotor includes a plurality of rotor cores arranged in a circumferential direction of the rotor, a plurality of magnets each disposed between neighboring ones of the rotor cores such that the magnet extends in an axial direction of the rotor outwardly of upper and lower surfaces of the neighboring rotor cores, and a molded body to support the plurality of rotor cores and the plurality of magnets. The molding body includes a shaft hole, to which a motor shaft is coupled.
摘要:
An apparatus for magnetizing magnets provided among a plurality of cores of a motor of a washing machine and a method thereof, is capable of fully magnetizing a magnet forming a rotor and including a plurality of teeth disposed around two cores of the plurality of cores, the two cores being laterally provided while interposing one of the magnets therebetween, and a coil being provided around the plurality of teeth to form a magnetic flux to magnetize the one magnet interposed between the two cores laterally provided.

A washing machine and a method for controlling the same are disclosed. The washing machine detects a back electromotive force of a washing motor, and controls output of an alarm sound by analyzing periodicity of a waveform period of the back electromotive force. The washing machine determines whether a child or pet is in a drum washing machine on the basis of the back electromotive force generated from the washing motor, and informs a user or guardian of the determined result.
