[0007] In the motor of the prior art as described above, the winding portion 21 of the upper insulator 20 and the winding portion 31 of the lower insulator 30 will constitute a structure that covers both sides, the upper and lower surfaces and the back of each tooth 13. When coils are wound in the winding parts 21, 31, it is necessary to reduce the space for winding coils corresponding to the thickness of the winding parts 21, 31 formed on the two sides of each tooth 13, and the reduction of the above-mentioned space will limit The number of windings of the coils that can be wound in the above-mentioned winding parts 21, 31 and the diameter of the coils

[0043] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

[0044] The drum washing machine is taken as an example for description. In general, the washing method of the drum washing machine is as follows: in a state where detergent, washing water and laundry are put into the drum, the washing operation is performed by using the friction force between the drum rotated by the driving force of the motor and the laundry. The above-mentioned drum washing machine can make the laundry hardly damaged, and the laundry will not be entangled with each other, and at the same time, the washing effect of scrubbing can be obtained. In addition, according to the driving method, the drum washing machine can be divided into: the indirect connection method in which the driving force of the motor is indirectly transmitted to the drum through the belt wound around the pulley of the motor and the drum pulley; the rotor of the motor is direct...

Abstract

The invention relates to a motor, in particular to a motor which does not reduce space between adjacent cogs of a stator mold core and can increase the winding number of a coil hereby. The motor can be the one applicable to washing machines, but is not limited therein. In the motor and the barrel washing machines installed with the motor, insulators at the upper part and the lower part and adjacent to the upper side and the lower side of the cog of the stator mold core can widen the utilizable space between adjacent cogs.

Description

technical field [0001] The present invention relates to a motor {MOTOR}, in particular to a motor that can increase the number of coils without reducing the space between adjacent teeth of the stator core. The motor in the present invention may be a motor suitable for washing machines, but the present invention is not limited thereto. Background technique [0002] In general, a motor transmits a rotational force of a rotor to a rotating shaft, and drives a load through the rotating shaft. For example, the rotating shaft may be connected to a drum of a washing machine to rotate the drum, or connected to a fan of a refrigerator to drive the fan to supply cool air to a desired space. [0003] figure 1 It is an exploded perspective view of the stator of the motor. The stator generally includes a stator core 11 , an upper insulator 20 and a lower insulator 30 . [0004] The stator core 11 includes: an annular back yoke 12 protruding radially outward along the outer peripheral...
