Abstract

The invention relates to the technical field of motors, and discloses a pin winding type motor stator and a motor. The pin winding type motor stator comprises a stator iron core, wherein the stator iron core comprises multiple layers of stator grooves and a stator yoke part; pin windings are wound in the stator grooves, each pin winding is provided with three phases, each phase of pin winding comprises two winding units which are connected in parallel, each winding unit is formed by connecting in series in a forward wave winding mode and a reverse wave winding mode, and each winding unit penetrates through the multiple layers of stator grooves. The pin windings of the pin winding type motor stator provided by the invention adopt forward and reverse wave winding modes; a certain phase difference is formed by conductor current distribution in the stator grooves, the skin effect of the motor during high-speed operation is effectively inhibited, the winding connection arrangement is optimized, the half-turn length of all coils in the windings is shortened, the sectional area of a busbar is increased, the alternating current resistance and loss of the winding are obviously reduced, andthe working efficiency of the motor is improved. Compared with the alternating current loss without the phase difference, the winding scheme with the phase difference reduces the alternating current loss by 30W.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a pin-winding motor stator and motor. Background technique [0002] The motor is configured with a stator and a mover that moves relative to the stator. The stator of the motor can be configured with a stator core, the stator core has a plurality of stator slots, and the stator windings are wound on the stator slots. In the prior art, when the pin-winding motor is running at high speed, the AC loss of the winding is relatively large, which leads to serious heating of the motor and low working efficiency of the motor. Therefore, there is an urgent need to provide a pin winding motor stator to solve the above problems. Contents of the invention [0003] The purpose of the present invention is to provide a pin winding motor stator and motor, which reduces the AC loss of the winding and improves the working efficiency of the motor. [0004] For reaching this purpose, the present ...
