8A 3-Phase Stepper Drive, High-Current Output

8A 3-Phase Stepper Drive for High-Current Axes

The 8A 3-Phase Stepper Drive 3DM2080 is rated for up to 8.0 A of output current from an 80-220 VAC supply. Its higher current capacity makes it a match for larger 3-phase stepper motors that need more phase current to hold rated torque. Lyenwsin supplies this drive for industrial CNC and automation systems.

Drive Topology and Control

The drive converts controller-level step and direction signals, in either Pulse/Dir or CW/CCW pulse format, into three-phase motor excitation. It runs open-loop, so positioning is defined by commanded steps and there is no feedback loop to tune. This simplifies integration into PLC- and controller-driven axes.

Operational Protections

Overcurrent, overvoltage, and undervoltage protection monitor supply and load conditions continuously. Output shaping keeps noise and vibration low, supporting smoother motion in equipment that indexes or rotates repeatedly.

Key Specifications

• Output current: max 8.0 A
• Supply voltage: 80-220 VAC
• Control modes: Pulse/Dir, CW/CCW pulse
• Protection: overcurrent, overvoltage, undervoltage
• Operation: open-loop, low noise and vibration

Target Applications

It is appropriate for industrial automation, packaging machinery, compact CNC equipment, robotics, automated handling mechanisms, textile machinery, printing machinery, and food processing.

Selection Note

Pair the drive with a 3-phase motor whose phase current is within 8.0 A. The broad AC input range covers both 110 V and 220 V installation environments. Confirm the motor’s torque-speed curve against the application duty cycle. Lyenwsin’s engineers can help you size the motor and drive combination for high-current axes.

Distributor Support

Lyenwsin keeps the 3DM2080 in stock with matched high-current 3-phase motors and provides torque-speed data, wiring guidance, and configuration support so the drive can be deployed quickly on industrial CNC and automation systems. Our engineers can confirm the motor phase current and line supply for your installation, and we can help you plan the panel cooling needed for continuous high-current duty.
