New powerful driver-constant torque closed loop stepper driver
Can drive nema 23 and small nema 34 motor.Internal voltage rise system,make the stepper motor can have better performance in high speed.eg:external voltage AC24V,the internal voltage can rise to 97V,external voltage AC48V,the internal voltage can rise to 157V.And the motor can run to 4000rpm without load.Reach stepper motor's limited
