Hinge type stator and circle forming method thereof

Abstract

The invention discloses a hinge type stator structure, and relates to the field of motors. At present, a circle forming method of a motor stator structure generally adopts welding, and the cost is high, and a welding process generates large amount of heat, which affects insulation performance of the motor. The hinge type stator comprises a stator core and a stator coil. The stator core is formed by assembling a plurality of stator core blocks with grooves and flanges on two ends through the grooves and the flanges in sequence. Each stator core block is formed by stator teeth, a stator yoke anda pole shoe. A gap between two adjacent stator core blocks forms a stator slot, and the stator coil is wound around the stator teeth through the stator slot. The stator core blocks on the head and the tail, which are wounded with the stator coils, are embedded with each other through the grooves and the flanges to form the hinge type stator. The circle forming method of the technical scheme is very simple, and the stator core has high torsional strength after being rounded, and inner and outer roundness of the stator core is good, and a conventional welding process is not required. The methodreduces manufacturing cost, and effectively improves comprehensive performance of the motor.

Description

technical field [0001] The invention relates to a hinged stator and a method for forming the same, belonging to the fields of motor technology and motor manufacturing. Background technique [0002] Most of the traditional motor stator structure is a monolithic structure, such as figure 1 , in which the material between the stator slots and the stator yoke cannot be effectively used, which increases the material cost. The stator coil is wound on the stator teeth through the stator core slot through the winding nozzle of the special winding machine, and the slot full rate is relatively high. low, the winding efficiency is low, and the labor cost is increased. With the development of motor technology and the in-depth advancement of lean production, different types of motor stators such as linear type and block type have appeared, which improved the winding efficiency and winding quality, and increased the effective slot area. The motor power can be achieved higher. The stato...
