Description

Integrated motor stator wiring structure

The invention relates to an integrated motor stator wiring structure.

Motor types can be divided into single-phase motors and three-phase motors. The operating principle of three-phase motors is that when the coil windings are energized, a rotating magnetic field will be formed. The rotating magnetic field will drive the motor, causing the rotor output to generate speed and torque.
