Stepping Motor Drive: High Speed = Anti Resonance

Stepping Motor + High Power Drive

MF_SLA7026 drive is developed for Uni-polar stepping motors.

DC supply voltage: 24 to 48[V]

Phase Current: 0.5 to 3[A]

Auto Current Reduction: 50% of set current, 2 seconds after last pulse

Standby Current: < 70[mA]

Photo input power: 5 to 12[V], max. 90[mA] (

Control modes: Dir/Pulse, CW/CCW pulse

I have finished the project of high power stepping motor drive.

MF4806 manual; - Wide Input Range of Voltage [24 ~ 48V]; - High Output Current [1 ~ 6A]; - Microstepping 10x and 5x; - Full and Half step; - Anti-Resonance Control; - Optically Isolated Inputs of Pulse, Direction and Motor-Off; - Running Speed up to 3,000 rpm

I have two models of stepping motor. If you are looking for a high torque stepping motor, let me know. NEMA(National Electrical Manufacturers Association) standard

1) NEMA 23 (4S56Q : Saehan Electronics)

4.5V 2.0A Torque: 1.4Nm (200oz-in)
