Stepper Motor Driver Board Part No RM3DB
RM3DB stepper motor driver is a small size micro-stepping stepper motor driver based on the latest technology today. It is suitable for driving any 2 phase and 4 phase hybrid stepper motor. By using advanced bipolar constant current chopping technique it can deliver more speed and torque than that compared with traditional technologies. Motor heating is also reduced by its 3-state current control technology giving relatively small current ripple reducing motor heating.
| High torque at high speed at a low cost |
| Voltage from +Vdc to +32Vdc maximum. Current output up to 2.52 amps adjustable onboard with dip switches |
| TTL compatible and opto-isolated input signals, pulse frequency 400KHz. Voltage regulator supplied with each order to provide +5Vdc to power Opto-isolator circuit, complete with wiring diagram. |
| Automatic idle-current reduction, reducing motor heating |
| 3-state current control also reducing motor heating |
| 15 Selectable resolutions from 400 to 25000 pulses/rev. DIP switch selectable |
| Suitable for 4, 6 and 8 lead motors. 2 phase and 4 phase motors |
| DIP switch current setting with 8 settings |
| Short circuit, over voltage, low voltage protection |
| Easy wiring by screw terminals |
| Size 107 x 33 x 85mm. With built in heat sink. |
| Can be Mounted Vertically or Horizontally |
Applications:
Suitable for a wide range of stepper motors of Nema 17 and 23 range that would drive various types of machinery, suitable for use in applications including x-y tables, bench and desktop milling machines, lathes, cnc router tables, pick and place units and robotics applications. Particularly suited to applications where relatively high speeds with high torque and precision is required. We use these drivers in our machine control systems. Comes complete with wiring instructions . Data Sheet
Prices include Voltage regulator to supply +5Vdc for
opto-isolator
