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 present invention relates to the field of motor technology, and more particularly to a pin winding motor stator and a motor. Background technique [0002] The motor is configured with a distant movement with respect to the stator. The stator of the motor can be disposed with a stator core, a stator core having a plurality of stator grooves, and a stator winding is wound around the stator groove. In the prior art, when the pin winding motor is running at high speed, the winding exchange loss is relatively large, causing the motor to be severe, resulting in low operating efficiency. Therefore, there is an urgent need to provide a pin winding motor stator to solve the above problems. Inventive content [0003] It is an object of the present invention to provide a pin winding motor stator and a motor, which reduces winding exchange loss, and improves the working efficiency of the motor. [0004] In order to reach this, the present invention adopts the foll...
