A coil lead terminal block is attached to the end face of the frame disk outside the stator body. The terminal block has a printed circuit for connection. The coil lead wire ends are electrically connected to the printed circuit of the terminal block. The wiring on the terminal block is connected to the driver. When installing and fixing the motor with other equipment, in addition to fixing the motor, it is also necessary to fix the driver, making installation difficult.

During motor handling, the driver is easily bumped or dropped, and the wiring may also be damaged.

[0003] To address these technical problems, an integrated toothed motor is proposed. Utility Model Content
