Problems solved by technology

[0003] Existing motors often have a large outer periphery of the stator, which cannot be adapted to common home appliances with a small volume. During processing, the cage bars of the rotor often have to be processed by turning, and the resulting iron cutting will affect the efficiency of the rotor and scratch the inner cavity of the stator. , reducing the efficiency and life of the entire motor

Embodiment Construction

[0015] Example. A miniature motor such as figure 1 As shown, it includes stator 1 and rotor 2; the cross section of stator 1 is square with a side length of 90 mm, and the cross section of rotor 2 is circular with a diameter of 56 mm. A rotor hole 3 is arranged in the center of the cross section of the stator 1, and a line slot group 4 is arranged around the rotor hole 3. The wire slot group 4 includes 8 large wire slots 5 and 16 small wire slots 6, one large wire slot 5 and 2 small wire slots 6 are distributed in groups; the height of the large wire slot 5 is 11.8mm, and the small wire slot 5 The height is 9.23mm; the wire grooves in the wire groove group 4 are evenly distributed in a ring around the rotor hole 3 . A rotating shaft hole 7 is provided in the middle of the rotor 2; a group of ventilation holes 8 is provided around the rotating shaft hole 7; a group of cage bars 9 are provided on the edge of the iron core, and a pair of slotted cage bars 10 are arranged in the...

Abstract

The invention discloses a miniature motor which comprises a stator (1). The cross section of the stator (1) is square, the side length of the stator (1) is 90mm, a rotor (2) is sleeved in the stator, the cross section of the rotor (2) is circular, and the diameter of the stator (2) is 56mm. The miniature motor has the advantages that the overall dimension of the stator is reduced, so that the miniature motor is applicable to common household appliances with small sizes; the quantity of lathed cage bars required by the rotor is reduced on the premise that the performance of the miniature motor is unaffected, scrap iron is reduced in a machining process, and influence of the scrap iron to the rotor after lathing is reduced; and scratching to an inner cavity of the stator is prevented, the efficiency of the integral motor is improved, and the service life of the integral motor is prolonged.

Description

technical field [0001] The invention relates to a miniature motor and belongs to the field of motors. Background technique [0002] Motors are products that are often used in daily life and are widely used in most household appliances. [0003] Existing motors often have a large outer periphery of the stator, which cannot be adapted to common home appliances with small volumes. During processing, the cage bars of the rotor often have to be processed by turning, and the resulting iron cutting will affect the efficiency of the rotor and scratch the inner cavity of the stator. , reducing the efficiency and life of the entire motor. Contents of the invention [0004] The purpose of the present invention is to provide a miniature motor, which can be used for common home appliances with small volume, reduce iron chipping during processing, prevent scratching of the inner cavity of the stator, and increase the efficiency and life of the entire motor. [0005] In order to solve ...
