4.8A 3-Phase Stepper Drive for Open-Loop Axes

4.8A 3-Phase Stepper Drive for Light-to-Medium Torque

The 4.8A 3-Phase Stepper Drive 3DM3422 provides up to 4.8 A of output current from a flexible 80-230 VAC supply. It is sized for 3-phase stepper motors in the light-to-medium torque class used across industrial motion control. Lyenwsin supplies this drive for robotics, automated handling, and packaging machinery.

Command Handling

Supported Pulse/Dir and CW/CCW pulse modes allow direct connection to common CNC controllers. Open-loop operation removes the need for encoder feedback, so the drive runs deterministically on step count alone and requires no closed loop tuning.

Reliability Features

Overcurrent, overvoltage, and undervoltage protection respond to wiring and supply faults before they can damage the motor. The drive output is tuned for low noise and vibration, giving smooth motion that keeps machinery quiet and protects delicate mechanical components.

Key Specifications

• Output current: max 4.8 A
• Supply voltage: 80-230 VAC
• Control modes: Pulse/Dir, CW/CCW pulse
• Protection: overcurrent, overvoltage, undervoltage
• Operation: open-loop, low noise and vibration

Target Applications

The drive fits industrial automation, packaging machinery, compact CNC equipment, robotics, automated handling mechanisms, textile machinery, printing machinery, and food processing.

Pairing Guidance

Select a 3-phase motor with a per-phase current at or below 4.8 A. The dual-range AC input simplifies deployment across different mains voltages. Verify the motor torque at the required operating speed before finalizing the axis design. Lyenwsin provides motor-drive matching support and technical documentation.

Distributor Support

Lyenwsin keeps the 3DM3422 in stock with matched 3-phase motors and provides torque-speed data, wiring guidance, and configuration support. Our team can confirm the motor pairing and supply wiring before your project goes into production, and we keep spares and documentation available for maintenance planning. For multi-axis systems, we can review the combined supply load and recommend an appropriate transformer and protection layout for the cabinet, and help you confirm the wiring terminations match the drive terminals.
