Description

Technical Field

[0001] The present application belongs to the technical field of stepper motors, and specifically relates to a stepper motor driver with a protective structure. Background Art

[0002] A stepper motor is a motor that converts electrical pulse signals into corresponding angular displacement or linear displacement. Each time a pulse signal is input, the rotor rotates an angle or moves forward one step. The angular displacement or linear displacement output is proportional to the number of input pulses, and the speed is proportional to the pulse frequency. Therefore, stepper motors are also called pulse motors. A stepper motor driver is an actuator that converts electrical pulses into angular displacement. Stepper motors and stepper motor drivers constitute a stepper motor drive system.

[0003] For example, the patent with announcement number CN216532147U discloses a stepper motor driver with a protective structure, including a stepper motor driver, and the stepper motor driver includes a protective shell and a bottom plate. The stepper motor driver with a protective structure uses a protective shell to protect the driver, thereby extending the service life of the stepper motor driver, and uses an anti-collision block filled with stuffing cotton, which is fixedly installed on the top surface, back surface and both sides of the protective shell. When a collision occurs, the anti-collision block and the stuffing cotton absorb the energy generated by the collision, play a buffering role, extend the service life of the protective shell, reduce the maintenance cost of the stepper motor driver and the service life of the protective shell, and use a drying strip to absorb moisture in the air to avoid the protective shell from condensing in a humid environment or rainy season, resulting in the interface of the driver being corroded and damaged by moisture, and the circuit components in the driver being short-circuited by moisture, thereby inducing safety accidents.

[0004] However, the device is not equipped with components for extracting motor components from the protective mechanism. When the motor components need to be repaired or replaced, the small space inside the protective structure makes it difficult for workers to operate the motor components, resulting in increased difficulty in maintenance and repair. Utility Model Content

[0005] The purpose of the present application is to provide a stepper motor driver with a protective structure to solve the problem that the above-mentioned device is not equipped with a component for pulling out the motor component from the protective mechanism.
