A stator manufacturing process

Abstract

The invention discloses a motor, particularly the motor with a stator structure which is formed by circumferential equal division and splicing. The stator of the motor comprises an even number of circumferentially equally divided iron cores, coils wound on the iron cores and arranged to form a trapezoid, a printed circuit board (PCB) for connecting tail wires of the coils on each iron core, and a housing case with an open slot. Stator laminations on each iron core of the stator of the motor are high in stacking accuracy; slot fullness after the winding of each iron core is high; the splicing tail wires of each iron core are well processed, and winding in the motor is free from interference; and the coils of the stator are connected with the outside in a terminal way, so the motor is simple in connection and convenient to keep.

Description

technical field [0001] The invention relates to a motor stator, in particular to a stator manufacturing process. Background technique [0002] Such as figure 1 Shown is a schematic diagram of the internal structure of a general motor. The motor includes a stator 1 and a rotor 2. A coil 4 is wound on the stator pole 3. When the coil is energized, a magnetic field is formed between the stator and the rotor so that the motor rotates. [0003] Figure 2 shows the manufacturing process diagram of a general motor stator. On the thin silicon steel sheet 5, the stator steel sheet 6 is punched out by stamping, and a plurality of stator steel sheets are stacked together to form the stator core 7, and finally the stator 1 is manufactured by winding the coil on the iron core. [0004] The windings on the motor stator are usually wound on the magnetic pole teeth of the motor stator by means of the winding port, and there are many residual materials on the steel plate during th...

Problems solved by technology

However, in the manufacturing process of the spliced ​​stator, the assembly accuracy is not guaranteed when the stator punching is laminated, and it is easily affected by human factors, making the performance of the motor unstable; after winding with this method, the winding between the stator cores The wires are independent and not connected to each other, and it is difficult to handle the connecting wires. There are often many tail wires inside the motor; the motor is connected to the outside by wires, which are easy to wear and tear during long-term use
