Abstract

The invention discloses a high-density winding punching plate and relates to a motor component. The high-density winding punching plate comprises a yoke, wherein the yoke comprises an inner circle; aplurality of tooth parts are uniformly arranged on the inner circle along the circumference; a winding inlet hole and a winding outlet hole are also arranged in the yoke; front connection ends and rear connection ends connected with a winding are arranged in the winding inlet hole and the winding outlet hole; the front connection ends are connected with the corresponding rear connection ends through conductive buckles; a temperature detector is arranged in one tooth part; and insulating wedges which are controlled by the temperature detector to open and close the conductive buckles are also arranged in the winding inlet hole and the winding outlet hole. A winding cut-off device is arranged in the punching plate, so that a winding power supply can be automatically cut off when the winding is overheated, the damage to a motor due to overheating of the winding is avoided and the power supply can be automatically connected after the temperature is reduced to a reasonable range, thereby ensuring normal operation of the motor.

Description

technical field [0001] The invention relates to a motor component, in particular to a stator stamping. Background technique [0002] The motor will generate a lot of heat during operation. For this reason, the stator and rotor of the motor will be designed with an air guide structure. Through the kinetic energy generated during the operation of the motor, the external air can take away the heat inside the motor, so that the windings are stable during operation. It can maintain normal temperature and ensure the normal operation of the motor. However, once the motor is short-circuited or overloaded, the temperature of the winding will rise sharply, which will have a great impact on the operation of the motor. In severe cases, the winding will be blown or the motor will explode. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides a high-density winding punch, which is provided with a winding power cut-off device, whi...
