Stepper motor micro-driver

Abstract

The invention discloses a stepper motor micro-driver, which comprises a base, a shell fixedly installed on the top of the base, a fixed plate fixed between the left and right sides of the inner wall of the shell, a circuit board fixed to the top of the inner surface of the shell, and a temperature sensor arranged on the right side of the bottom of the circuit board. The invention relates to the technical field of stepper motor drivers. The stepper motor micro-driver can automatically detect the short circuit of the micro-driver and give an alarm to remind the staff to power off the micro-driver for maintenance quickly. The heat inside the driver can be dissipated quickly, so that the damage degree of the driver is greatly reduced. Through a first heat conducting block, a second heat conducting block and coolant, the heat inside the micro-driver can be dissipated quickly, and the micro-driver can be maintained at high working efficiency. A dust cover can prevent dust from entering the interface of the micro-driver.

Description

technical field [0001] The invention relates to the technical field of stepping motor drivers, in particular to a stepping motor micro driver. Background technique [0002] A stepper motor driver is an actuator that converts electrical pulses into angular displacement. When the stepper driver receives a pulse signal, it drives the stepper motor to rotate a fixed angle (called "step angle") in the set direction, and its rotation runs step by step at a fixed angle. The angular displacement can be controlled by controlling the number of pulses, so as to achieve the purpose of accurate positioning; at the same time, the speed and acceleration of the motor rotation can be controlled by controlling the pulse frequency, so as to achieve the purpose of speed regulation and positioning. [0003] During the use of the existing stepper motor driver, if the internal circuit is damaged due to short circuit, the staff cannot be reminded in time, resulting in more serious damage to the dr...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a stepper motor micro-driver, which solves the problem that if the internal circuit is damaged due to a short circuit, the staff cannot be reminded in time, resulting in more serious damage to the driver, or even damage to the stepper motor, and Existing drives dissipate heat by opening heat dissipation holes on the casing, the heat dissipation holes are easy to enter dust, and the heat dissipation effect is poor
