Description

Technical Field

[0001] The invention relates to the technical field of motor equipment, and in particular to a vibration-reducing, noise-reducing and dust-removing capacitor motor using a voltage relay. Background Art

[0002] Electric machinery (English: Electric machinery, commonly known as "motor") refers to an electromagnetic device that realizes electrical energy conversion or transmission according to the law of electromagnetic induction; the motor is represented by the letter M (the old standard uses D) in the circuit, and its main function is to generate driving torque, as a power source for electrical appliances or various machines. The generator is represented by the letter G in the circuit, and its main function is to convert mechanical energy into electrical energy. The direction of the force on the conductor is determined by the left-hand rule; this pair of electromagnetic forces forms a torque acting on the armature, which is called electromagnetic torque in the rotating motor. The direction of the torque is counterclockwise, attempting to make the armature rotate counterclockwise; if this electromagnetic torque can overcome the resistance torque on the armature (such as the resistance torque caused by friction and other load torques), the armature can rotate counterclockwise.

[0003] For the existing motors, a mechanical centrifugal switch is usually used, which is usually composed of two parts, a centrifuge installed on the rotor and a centrifugal switch base plate installed on the end cover. When the motor is stationary, the contacts are in a closed state under the action of the centrifuge spring; when the motor is energized, the motor speed begins to increase, and the motor speed is determined by its own centrifugal force. If the motor speed reaches 70%-80% of the rated speed, the mechanical switch is disconnected by the centrifugal force to achieve the purpose of starting the motor. However, it occupies a large space, resulting in an increase in the size of the motor, and troublesome maintenance. During maintenance, the rotor and the rear end cover of the motor need to be disassembled for replacement. In addition, the motor has a certain noise when working, which affects the working environment. While the motor dissipates heat, it does not have a good effect of preventing dust and impurities in the outside air from entering the motor, which may affect the normal operation of the motor parts for a long time. During the working process, vibration will also be generated, which will affect the service life of the motor.
