Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a motor with noise reduction effect. Background Art

[0002] A motor is a device that converts electrical energy into mechanical energy. It generates rotational or linear motion through the input of electrical energy, thereby driving the movement of other mechanical devices. Motors are widely used in various industrial, commercial and household equipment, including mechanical equipment in factories, transportation vehicles such as electric cars, and household appliances such as washing machines and vacuum cleaners.

[0003] There are two types of motors: DC motors and AC motors. DC motors are powered by a DC power supply and use the armature and magnetic field to generate rotational force. AC motors are powered by an AC power supply and use alternating current to generate a magnetic field in the motor's coils, thereby generating rotational force.

[0004] The principle of the motor is based on the principle of electromagnetic induction, the most common of which is the effect of the Lorentz force. According to Faraday's law of electromagnetic induction, when current passes through a wire, a magnetic field is generated around the wire. When the wire is placed in an external magnetic field, the external magnetic field interacts with the magnetic field inside the wire, generating a force to move the wire. The motor uses this principle to convert electrical energy into mechanical energy.

[0005] China's motor manufacturing industry is developing rapidly, and its export volume is in a leading position in the world. The Chinese government supports the development of the motor industry and promotes the innovation and improvement of motor technology.
