Abstract: A washing machine includes a controller for controlling a series of washing processes. In a first process, the controller sets a clutch to a first mode in which a rotation of a motor is transferred to a rotating tub via a reducer, and controls the motor to allow the rotation tube to rotate with a first rotation speed which is greater than or equal to a certain rotation speed set to generate a centrifugal force to make laundry stuck to an internal wall of the rotating tub. In a second process after the first process, the controller sets the clutch to a second mode in which the rotation of the motor is transferred to the rotating tub without being through the reducer, and controls the motor to allow the rotating tub to rotate with a second rotation speed which is greater than the first rotation speed.

Abstract: A washing machine including a rotary drum that is rotatable, and into which laundry is loadable; a motor configured to rotate the rotary drum; and a controller configured to perform startup control to initiate rotation of the rotary drum, the startup control including a first process for controlling the motor so that torque for rotating the rotary drum in a first rotation direction is applied to the rotary drum; and a second process for controlling the motor so that, after the first process is initiated, and when a rotational acceleration of the rotary drum is less than or equal to a first predefined threshold before a rotation velocity of the rotary drum reaches a first rotation velocity, torque for rotating the rotary drum in reverse is applied to the rotary drum.

Abstract: Provided is a washing machine including a motor configured to suppress an increase in a harmonic component of cogging torque even when a magnetization imbalance occurs. The motor of the washing machine may include a rotor configured to rotate about a rotation axis, and a stator facing the rotor with an air gap therebetween, wherein the rotor includes an annular magnetic pole body in which a plurality of magnets having an arc-shaped cross-section are arranged in a circumferential direction of the rotor, and the annular magnetic pole body includes two or more types of magnets having different numbers of magnetic poles.

Abstract: A washing machine includes a controller. The controller perform switching processing, by moving a moving part in an axial direction so that the moving part is switched from a start state in which one of a rotor-side fixing part and a stator-side fixing part engages with the moving part to an end state in which a remaining one of the rotor-side fixing part and the stator-side fixing part engages with the moving part. The controller is further configured to perform an adjustment operation before the end state of the switching processing starts. In the adjustment operation, the controller is further configured to adjust an engagement position by changing a rotation phase of rotor so as to allow an engagement position of the moving part with respect to the remaining one of the rotor-side fixing part and the stator-side fixing part to become a target engagement position.
