Embodiment Construction
[0010] Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:
[0011] Such as figure 1 As shown, the matching structure of the two-pole motor slot includes the stator punching body 2 and the rotor punching body 6. The stator punching body 2 is annular, and the inner edge of the stator punching body 2 is evenly along the stator punching body. 2, several stator slots 3 are punched in the circumferential direction, the centerlines of the stator slots 3 all point to the center of the stator punch body 2, and the openings of the stator slots 3 are located on the inner edge of the stator punch body 2, and the The opening width of the stator slot 3 is less than the width of the stator slot 3; the rotor punch body 6 is also annular, and the outer diameter of the rotor punch body 6 is smaller than the inner diameter of the stator punch body 2; The outer edge is evenly provided with rotor slots along the circumferential di...

The invention relates to a manufacturing technology of a motor, in particular to a matching structure of a dipolar motor slot, which is mainly used for reducing the noise of an Y2-160 dipolar motor. The matching structure comprises a stator punching body and a rotor punching body and is characterized in that a slot form of the stator punching body is unchanged, 36 slots are punched on the stator punching body, and 28 slots are punched on the rotor punching body. The invention has simple, compact and reasonable structure and remarkable effect; under the conditions of not changing structure materials, core length and an air gap between a stator and a rotor, the original matching slots on the stator punching body and the rotor punching body of the motor are changed into 36 / 28, that is to say, the slot form on the stator punching body is unchanged, and the 36 slots are punched on the stator punching body; the slot form on the rotor punching body is also unchanged, and the 28 slots are punched on the rotor punching body; therefore, the property reaches standard requirements comprehensively, and especially the noises are all in satisfied statuses.
Description
technical field [0001] The invention relates to a manufacturing technology of a motor, in particular to a matching structure of a two-pole motor slot; it is mainly used for reducing the noise of a Y2-160 two-pole motor. Background technique [0002] Asynchronous motor is the most widely used type of motor. Due to the improvement of people's requirements on motor performance and environmental quality, the noise of motors has become an increasingly important technical index to measure the quality level of motors. There are many reasons for the high noise of the motor, and the number of slots of the stator and rotor of the motor, the so-called slot fit, is one of the important factors affecting the noise of the motor. The 112, 132 and 160 frame size two-pole motors of the Y, Y2, and Y3 basic series that are used in large quantities in my country have always used the 30 / 26 slot fit (that is, the stator punch has 30 slots, and the rotor punch has 26 slots). When this slot is mat...
