Problems solved by technology

[0005] In the production process of the existing brushless motor, one is to fix the PCB board on the housing first, and then assemble the PCB board and the upper insulating bracket through the terminal connection holes on the PCB board and the terminals on the upper insulating bracket. At the same time, in the actual production of this assembly method, due to the large error in the relative position between the terminal connection hole on the PCB board and the terminal on the upper insulating bracket, defective products are prone to appear in the automated production process; another It is to install the PCB board on the upper insulating bracket first, and then directly weld the wires of the stator winding to the PCB board. In actual production, this assembly method needs to manually solder the wires of the stator winding to the PCB board. Therefore, it is difficult Automate

Description

technical field [0001] The invention relates to the technical field of brushless motors, in particular to a positioning structure for a PCB board and an upper insulating support. Background technique [0002] A brushless motor is a motor without brushes and commutators (or collector rings), which operates by changing the alternating frequency and waveform of the current wave that passes into its stator winding coil. Brushless motors are widely used by major manufacturers because of their high efficiency, low energy consumption, low noise, long life, high reliability, servo control, stepless frequency conversion speed regulation, relatively low cost and ease of use. [0003] The existing brushless motor mainly includes: a housing, a printed circuit board ("PCB" for short), a rotor, and a stator. The stator includes: an upper insulating bracket, a stator core, a lower insulating bracket, and a stator winding. The upper insulating bracket and the lower insulating bracket are r...
