Mini Stepper Driver (2 Phase)

Mini 2-Phase Stepper Drivers for Compact Automation

Runcin mini 2-phase stepper drivers provide reliable pulse control in a space-saving housing. The range includes five models for small and medium automation equipment. Therefore, engineers can select a driver according to motor size, supply voltage, current and microstep requirements.

Each model supports pulse-and-direction control and a response frequency up to 200 kHz. In addition, motor parameter auto-tuning helps the driver match different two-phase stepper motors. Built-in protection functions also support safer machine operation.

Compact Drivers for Different Motor Sizes

The R2D1725-Mini stepper driver suits compact 35, 39 and 42 series motors. It accepts DC 18–36V input and delivers up to 2.5A peak current. Moreover, users can set microstepping from 400 to 6400 pulses per revolution.

For larger motors, the R2D2342-Mini supports DC 20–50V and up to 4.2A. The R2D2356-Mini raises the peak current to 5.6A. Both models offer subdivisions up to 25600 pulses per revolution. As a result, machine builders gain more freedom when tuning speed and smoothness.

Higher-Current Models and Product Selection

The R2D2472-Mini accepts DC 24–80V or AC 18–55V. It provides 7.2A peak current and subdivisions up to 51200 pulses per revolution. Meanwhile, the R2D3472-Mini supports DC 24–110V or AC 18–80V. Therefore, it fits larger two-phase motors and higher-voltage systems.

These compact drivers suit engraving machines, packaging equipment and electronic processing systems. They also support CNC machines, feeders and automated assembly equipment.

Before choosing a model, compare the motor current, inductance and frame size. Also confirm the power supply, pulse frequency and installation space. This review helps improve system compatibility and long-term reliability.
