Description

Technical Field

[0001] The present invention relates to the technical field related to motors, and in particular to a gear-shifting motor. Background Art

[0002] The motor is a device that converts electrical energy into mechanical energy. It is made by using the phenomenon that the energized coil rotates under force in the magnetic field. It is distributed at various users. The motor is divided into DC motor and AC motor according to the power source used. Most of the motors in the power system are AC motors, which can be synchronous motors or asynchronous motors (the speed of the motor stator magnetic field and the speed of the rotor rotation do not maintain synchronous speed). The motor is mainly composed of a stator and a rotor. The direction of the force movement of the energized wire in the magnetic field is related to the direction of the current and the direction of the magnetic flux lines (magnetic field direction). The working principle of the motor is that the magnetic field acts on the force of the current, causing the motor to rotate.

[0003] At present, most of the motors used in electrical appliances such as grinders and wall breakers on the market have the function of speed change. However, although the existing variable speed motors can achieve the function of speed change through the matching connection between gears, it is not convenient to switch the speed gears, which reduces the user experience of the variable speed motor. In addition, the multiple gears in the existing variable speed motors will wear each other when working, or rust and become difficult to rotate. In this case, the user needs to disassemble the casing of the speed change assembly to oil the gear structure. This oiling method is obviously too time-consuming and labor-intensive, which greatly reduces the practicality of the variable speed motor. Summary of the invention
