Self-cleaning stepping motor

Abstract

The invention provides a self-cleaning stepping motor, and belongs to the technical field of motors. A positioning block is arranged at one end of a rotor shaft, a rotating disc with a spiral groove and fan blades is arranged at one end of the rotor shaft in a sleeving mode, an abutting bearing and a spring are arranged between one side of the rotating disc and the side, provided with the positioning block, of the rotor shaft, and a magnet block and an electromagnet which repel each other are arranged between the other side of the rotating disc and a second end cover, so that after the electromagnet is powered on, the rotating disc can be pushed to move towards one side of the positioning block, so that the positioning block is clamped into the spiral groove, the rotor shaft can drive the rotating disc with the fan blades to rotate, air blowing to the interior of the motor is achieved, self-cleaning is achieved, and after the electromagnet is powered off, the rotating disc can be far away from the positioning block under the action of the spring, so that the rotating disc does not rotate along with the rotor shaft, energy waste is avoided, remote operation is achieved, operators do not need to enter the area for disassembly, assembly and maintenance, operation is convenient, the service life of the motor is prolonged, and use and popularization of the motor are facilitated.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a self-cleaning stepping motor. Background technique [0002] As a commonly used driving structure, stepper motors are used in all walks of life, and as linear drive stepper motors, they can achieve axial telescopic movement and are widely used in lifting devices. [0003] However, due to the limitation of the use environment, if the stepper motor is installed in a narrow space and a low or high position, it is difficult for the operator to enter this area, which will cause great inconvenience to the later maintenance of the stepper motor . In addition, during long-term use, impurities such as dust and cotton wool floating in the air can easily enter the interior of the stepper motor, stick to the stator and wrap around the rotor, increasing friction and adding extra energy The loss and heat are large and consume electricity. If it is serious, the motor will be burned, which wil...

[0003] However, due to the limitation of the use environment, if the stepper motor is installed in a narrow space and a low or high position, it is difficult for the operator to enter this area, which will cause great inconvenience to the later maintenance of the stepper motor

In addition, during long-term use, impurities such as dust and cotton wool floating in the air can easily enter the interior of the stepper motor, stick to the stator and wrap around the rotor, increasing friction and adding extra energy The loss and heat are large and consume electricity. If it is serious, the motor will be burned and the service life of the motor will be shortened, which is not conducive to the use of the motor.
