Automatic coil winding machine of direct-current brushless motor with high slot space factor

Abstract

The invention provides an automatic coil winding machine of a direct-current brushless motor with a high slot space factor. The automatic coil winding machine comprises a transverse rotating structure and a longitudinal incoming line structure. The longitudinal incoming line structure is connected with the transverse rotating structure through a pressing line structure. The transverse rotating structure comprises a main shaft flange, a main shaft, a thread hooking disc, an iron core to be wound, a locking nut, a pressing line base and a pressing line pin. The longitudinal incoming line structure comprises a limiting door sheet, a door frame, a coil nozzle, a line nozzle connecting plate, rollers, an auxiliary tension mechanism, an auxiliary tension spring, a line guiding wheel, a threading magnetic coil, a tensioning spring rod, a tension spring and a line clamp block. The automatic coil winding machine of the direct-current brushless motor with the high slot space factor can replace manual operation, and is high in efficiency and speed, simple in structure, reasonable in design, accurate in positioning, rapid to assemble and disassemble, simple in equipment structure, low in purchase cost, and easy to popularize in a large-scale mode.

Description

technical field [0001] The invention relates to the field of automatic machinery, in particular to an automatic motor winding machine. Background technique [0002] Now electric vehicle drive motors are basically rare earth permanent magnet brushless DC motors. In order to meet the speed requirements of electric vehicle customers, the method of adjusting the number of turns of the motor winding is generally used to adjust the speed of the motor. But for windings with a low number of turns, if one turn is adjusted, the speed of the motor will vary greatly, which cannot meet the requirements of users. [0003] Usually DC motors have a "commutator", which can only be installed at one end of the winding, and the two ends of each coil of the winding must be connected to the corresponding commutator, so the coil must be an integer number of turns (turns). Even ordinary motors basically have distributed windings, which can only be windings with integer turns. But the characterist...

Problems solved by technology

[0004] Problems existing in similar technologies: 1. Manual winding: high labor intensity, low output, and unstable product quality

2. Traditional flying fork winding machine: not suitable for motor coils with high slot full rate, and the qualified rate of finished coils is low

During the winding process, the diameter of the enameled wire will change, which will affect the performance of the motor
