Abstract: Disclosed is a method for reducing vibration during dehydration of a washing machine having a ball balancer provided to a spin basket for accommodating clothes. The disclosed method for reducing vibration comprises: a test rotation step for rotating the spin basket at a measurement rotation count, which is lower than a resonance rotation count and at which the balls of the ball balancer move in a circle; a vibration period measurement step for measuring a vibration period of the spin basket, the vibration period being caused by the eccentric distribution of the clothes in the test rotation step; and an acceleration start timing acquisition step for acquiring acceleration start timing on the basis of the vibration period such that the balls and the eccentrically distributed clothes are arranged to face each other in opposite phases during resonance, when the rotation count of the spin basket passes the resonance rotation count if there is acceleration at a preset determined acceleration speed from the measurement rotation count.

Abstract: The present disclosure includes a washing machine including an inner rotor and an outer rotor. An outer rotor and an inner rotor may be rotated in a synchronous rotation mode or a counter rotation mode by converting the number of magnetic poles of the outer rotor. When the outer rotor becomes inoperable when the outer rotor is set to the number of magnetic poles for performing the counter rotation mode, it is converted to the number of magnetic poles for performing the synchronous rotation mode while the outer rotor is stopped.

Abstract: A washing machine capable of independently driving two rotors using one inverter in a simple configuration without supplying a composite current includes an outer rotor having a plurality of switching magnets arranged at intervals in the circumferential direction, and an inner rotor having a plurality of stationary magnets arranged to be radially arranged at intervals in the circumferential direction. When a magnetizing current is supplied to the coil of the stator, the magnetic pole of the switching magnet is inverted and the number of the poles of the outer rotor is switched.

Abstract: Provided is a washing machine motor capable of efficiently generating torque by improving a winding factor of coils with a relatively simple configuration. The washing machine motor (12) has an outer rotor (20), an inner rotor (30), and a stator (60). The outer rotor (20) and the inner rotor (30) share coils (63) of the stator (60), and a composite current is supplied to the coils (63) such that the outer rotor (20) and the inner rotor (30) are independently driven. The outer rotor (20) has forty eight outer magnets (24) arranged such that the N and S poles thereof are continuously and alternately aligned in the circumferential direction thereof. The inner rotor (30) has forty-two inner magnets (34) arranged such that the N and S poles thereof are continuously and alternately aligned in the circumferential direction thereof. The stator (60) has thirty-six I-shaped cores (61) and the coils (63).

Abstract: A motor has a two rotors which are independently operated using a single inverter and without being supplied with a complex current. Further the motor is capable of shifting a rotation direction of each of two rotors by performing a magnetizing operation one time and reversing polarities of the shifting magnets when a mode of the motor is shifted from a synchronous mode in which the first rotor and the second rotor rotate in the same direction to a counter mode in which the first rotor and the second rotor rotate in opposite directions, and shifting the mode of the motor to the counter mode while the magnetizing operation is performed one time times and relative positions of the first rotor and the second rotor are changed when the first rotor and the second rotor inertially rotate in the synchronous mode.

Abstract: A washing apparatus is provided. The washing apparatus includes a tub, a drum configured to be rotatable in the tub, a pulsator configured to be rotatable in the drum, a driver configured to drive the drum and the pulsator, and a controller configured to control the driver to rotate the pulsator to a second direction while rotating the drum to a first direction. The controller controls the driver to drive the pulsator based on a position of laundry accommodated in the drum during a rotation of the drum.
