Tips: Single-shaft stepper motor driver
The stepper motor driver drives the stepper motor using the point pulse signal received from the controller. It is in the middle of the controlling unit: Controller - motor driver - stepper motor. Stepper motor drivers are divided into single-shaft driver and double-shaft driver. We usually use a single-shaft driver. One single-shaft stepper motor driver transfers processed pulse signals to another stepper motor while one double-shaft stepper motor driver transfers processed pulse signals to another two stepper motors. That is, a double-shaft driver driving two stepper motors is rare on the current market.
ATODSP86 is digital 2-phase stepper motor driver, it is widely used in middle and big size numerical control devices such as curving machine, CNC machine, and computer embroider machine, packing machine and so on. Capable of driving Nema 23, 34, 42 closed-loop hybrid 2 phase stepper motors.
