Description

Technical Field

[0001] This invention relates to the field of driver technology, and in particular to a bus stepper driver for robots. Background Technology

[0002] A stepper motor driver is an actuator that converts electrical pulses into angular displacement. When a stepper driver receives a pulse signal, it drives the stepper motor to rotate a fixed angle (called the "step angle") in a set direction. Its rotation occurs step by step at fixed angles. The amount of angular displacement can be controlled by controlling the number of pulses, thus achieving accurate positioning. Simultaneously, the speed and acceleration of the motor can be controlled by controlling the pulse frequency, thus achieving speed regulation and positioning.

[0003] Existing bus-type stepper motor drivers have poor heat dissipation and short maintenance cycles. When the heat generated cannot be effectively dissipated, it can easily lead to unstable motor operation and shorten the service life. Summary of the Invention
