Abstract

The invention discloses a high-density winding punching sheet, and relates to a motor component. The high-density winding punching sheet comprises a yoke part, the yoke part comprises an inner circle,a plurality of tooth parts are uniformly arranged on the inner circle in the circumferential direction, a winding wire inlet hole and a winding wire outlet hole are formed in the yoke part, an elastic connecting part and a magnetic connecting part which are connected to a winding are arranged in each of the winding wire inlet hole and the winding wire outlet hole, elastic winding connecting terminals and magnetic winding connecting terminals are arranged on the elastic connecting parts and the magnetic connecting parts correspondingly, springs are arranged in the elastic winding connecting terminals, electromagnets are arranged on the end surfaces of the elastic winding connecting terminals, the magnetic connecting parts are provided with magnetic surfaces matched with the electromagnets,and temperature detectors are arranged in the tooth parts and control the electromagnets to be opened and closed. The high-density winding punching sheet has the advantages that a winding power-off device is arranged in the punching sheet, a winding power supply can be automatically cut off when the winding is overheated, so that damage to a motor due to overheating of the winding can be prevented, the power supply can be automatically connected after the temperature is decreased to a reasonable range, and normal use of the motor is guaranteed.

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 equipped with a winding power cut-off device, whi...
