2A 3-Phase closed loop Stepper Drive for Small Axes

The 2A 3-Phase closed loop Stepper Drive 3HCS2202-17BC is the low-current entry in the 3-phase closed loop range. It runs from a 150-240 VDC supply and is sized for smaller stepper motors in machines where the payload is modest but position reliability still matters. Lyenwsin offers this drive for food processing, printing machinery, and industrial automation lines.

Low-Current Design for Small Axes

A 2 A maximum output current covers small 3-phase stepper motors used in light indexing and feed axes. Because the drive still operates with full closed loop control, it detects and corrects missed steps that an open-loop drive would simply ignore. On machines that run thousands of cycles per day, that reliability directly affects scrap rates.

Command Modes

Pulse/Dir and CW/CCW pulse modes are supported, keeping the drive compatible with the majority of industrial motion controllers. Either convention can be selected without extra conversion hardware.

Thermal Performance

The drive is characterized by high efficiency, low heat generation, and low noise. The modest current rating keeps heatsink requirements low, which is convenient for compact OEM panels where space is limited.

Key Specifications

Type: 3-phase closed loop stepper drive
Supply voltage: 150-240 VDC
Max output current: 2 A
Command modes: Pulse/Dir, CW/CCW
Control: full closed loop
Operating characteristics: high efficiency, low heat generation, low noise

Typical Applications

Suitable for industrial automation, packaging machinery, compact CNC equipment, robotics, automated handling mechanisms, textile machinery, printing machinery, and food processing, especially where the axis is lightly loaded and speed is moderate.

Selection Considerations

Match the motor phase current to the 2 A capacity and confirm the motor can deliver the required torque at the bus voltage available. Because the supply range is high-voltage DC, verify the existing cabinet bus is compatible. Lyenwsin’s engineers can help confirm the motor and drive pairing for your specific axis.
