<P>PROBLEM TO BE SOLVED: To provide a washing machine, having an excellent vibration performance, in which both low-speed high torque and high-speed rotation are achieved and high efficiency and silent operation are realized. <P>SOLUTION: A washing machine includes a motor driving means 30 for driving a motor 13, a control means 20 for controlling the rotation of the motor 13 according to a washing sequence, and a connection form control means 32 for changing a connection form between a stator coil of the motor 13 and the motor driving means 30 when the motor 13 stops. The control means 20 has a 3D sensor 40 for detecting vibration of a housing cylinder 11 and controls the number of the rotation of the motor 13 depending on the output of the 3D sensor 40. The motor 13 has a mold part and heat radiating fins exposed outward and is fixed on an outer circumferential wall of the housing cylinder with the intervals of the heat radiating fins close to the housing cylinder. The washing machine, thereby, can achieve both low-speed high torque and high-speed rotation, realize high efficiency and silent operation, and obtain an excellent vibration performance. <P>COPYRIGHT: (C)2012,JPO&INPIT |
