AI Technical Summary
During the winding process, the ends of the wound rotor coils are prone to protrusion, which causes friction between the rotor and the casing when the rotor rotates, resulting in mechanical loss and noise, and affecting the normal operation of the motor.
The forming platform uses forming blocks and clamping components. The rotor coil is clamped by the clamping components, and the coil end is clamped and shaped along the rotor axis by the cooperation of the forming blocks and the abutment blocks, so as to ensure that the coil end is not easily rubbed against the housing.
This reduces friction between the rotor coil and the housing, decreases mechanical loss and noise, and extends the service life of the motor.
