Motor stator with deformable iron core and preparation method thereof

Abstract

The invention discloses a motor stator with a deformable iron core. The motor stator with the deformable iron core comprises an iron core of a stator, coils and an insulation component, wherein the iron core of the stator is formed by stacking of a plurality of one-piece type chips. The motor chip comprises a magnetic ring, and Y-shaped magnetic poles protruding along the inner side face of magnetic ring and arranged evenly along an axial direction. Two magnetic pole wings of the Y-shaped magnetic poles can be expanded to two sides, wire casings are formed between two adjacent magnetic poles and by the inner side face of the magnetic ring, notches are formed at edges of two opposite magnetic pole wings of the magnetic pole, and widths of the notches are correspondingly changed with expansion of the magnetic pole wings. The coils are sleeved at the trunk of the Y-shaped magnetic poles and are arranged at wire housings at two sides of the trunk. The insulation component is arranged between the iron core and the coils and enables the stator iron core to be insulated with the coils. The invention further provides a manufacturing method of the motor stator with a deformable iron core. Due to the deformable magnetic pole, the manufacturing method of the motor stator with the deformable iron core enables the notches to be small, does not need to wind coils directly on the stator iron core to improve craft efficiency, and slot fill factors of the wire housings are high.

Description

technical field [0001] The invention relates to a motor stator, in particular to a motor stator provided with a deformable iron core. The invention also relates to a method for preparing a motor stator provided with a deformable iron core. Background technique [0002] The magnetic pole of the stator iron core of the existing motor is fixed T-shaped, and the coil is directly wound on the stator iron core by a special winding device. However, the price of a special winding equipment is more than 1.3 million yuan, which makes the equipment investment large; the production efficiency of this machine is low, and it can produce 20 stators per hour, so the process time is long, the production efficiency is low, and the process cost is high. Secondly, since the gap between the slots and the winding tool must be reserved so that the winding process can be carried out, the number of coil windings in the wire slots is not many, resulting in a low slot fill rate of the wire slots.

Problems solved by technology

However, the price of a special winding equipment is more than 1.3 million yuan, which makes the equipment investment large; the production efficiency of this machine is low, and it can produce 20 stators per hour, so the process time is long, the production efficiency is low, and the process cost is high.

Secondly, because the gap between the slots and the winding tool must be reserved so that the winding process can be carried out, the number of coil windings in the slots is not many, resulting in a low slot fill rate of the slots.

Furthermore, due to the requirements of the winding process, a certain width of the notch of the wire slot must be maintained, but a wider notch width will increase the vibration of the motor and reduce the efficiency of the motor
