Product Description

Nema 23 Stepper Motor Driver M545D ,18-50VDC,4.5A Nema 23 Nema 24 Stepping Motor



Changzhou Jinsanshi Mechatronics Co. Ltd. is located in Changzhou city, Jiangsu province, China. We are a comprehensive company which specializes in producing and researching motors and drivers.

Our main products include hybrid step motor, and step driver, step servo motor and driver, integrated step servo motor, linear stepper motor, geared stepper motor, stepper motor with brake, brushless dc motor. And we are always researching and developing new products.



    The M545D is a new generation microstep stepper motor driver. Due to the adoption of the advanced bipolar constant-current chopper driver technology, it shows stable operation, provides excellent high torque. Moreover, it significantly reduces the noises and vibration of the operating motor. The M545D has the feature of low-noise, low-vibration and low-heating. The M545D is DC18-50V power supply. It applies to 2-phase hybrid stepper motor under 4.5A current The M545D has 14l kinds of microsteps. The maximum step number is 51200 steps/rev (microstep is 1/256). The peak operating current ranges from 1.5A to 4.5A., and the output current has 8 stalls. The M545D has automatic semi-flow, motor misconnected,over-voltage, under-voltage, and over-current protection functions.




It can be applied in a variety of small scale automation equipment and instruments,  such as labeling machine, cutting machine, packing machine, drawing machine,  engraving machine, CNC machine and so on. It always performs well when it is used  in equipment which  requires  for low-vibration, low-noise, high-precision and high-velocity.
