Abstract

The invention provides a motor circuit board, comprising a first circuit board and a second circuit board, wherein a first bonding pad is arranged on a peripheral side of each first connection hole in a first circuit board body, and a plurality of first bonding pads are connected by a copper foil circuit arranged on the first circuit board body; second bonding pads are arranged on the peripheral sides of second connection holes and of power line connection holes in a second circuit board body respectively; a plurality of second bonding pads are connected by the copper foil circuits arranged on the second circuit board body; a group of bridge wires are welded between the first bonding pads and the second bonding pads, the other groups of bridge wires are respectively welded between two first bonding pads or two second bonding pads, and the copper foil circuits on the first circuit board body and the second circuit board body connect a plurality of bridge wires. The invention further provides a stator structure and a plastic package motor. According to the motor circuit board, the stator structure and the plastic package motor provided by the invention, the circuit connection process of the bridge wires of coil windings is simplified, and the assembly efficiency of the stator structure is improved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a motor circuit board, a stator structure and a plastic-encapsulated motor. Background technique [0002] Plastic-encapsulated motors generally include a stator and a rotor. Among them, the stator is generally formed by winding two semicircular stator cores and splicing them together. Therefore, during the assembly process of the motor stator, the bridge wire connecting the coil windings on the two semicircular stator cores Realize the circuit connection of the entire motor stator, and the connection between the bridge wires generally adopts the method of direct connection of enameled wires. This method requires manual arrangement of the bridge wire lines, wiring and welding lines, and the process is complicated, time-consuming and labor-intensive. , the assembly efficiency is low. Contents of the invention [0003] In view of the current state of the art, the purpose of the pr...
