Nema 11 (28mm) Integrated Stepper Servo Motor with Built-in Driver

SOYA NEMA 11 (28mm) Integrated Stepper Motor with Drive Series

The SOYA NEMA 11 (28mm) integrated stepper motor series is a highly compact, intelligent motion control actuator lineup engineered by SoyaMotor. Developed for high-precision, space-critical automation applications, this 28mm square smart motor natively integrates a high-performance digital drive and a 1000-line incremental optical encoder directly onto the motor chassis. Supporting dual control methods via Pulse+Direction or standard MODBUS-485 network commands, it delivers a speed range up to 3000 RPM with software-adjustable current parameters. Built upon our own factory floor, this advanced series effectively eliminates external drive wiring layouts, providing zero-step-loss positioning stability and built-in protections for medical laboratory automation, compact pipetting channels, handheld testing equipment, and micro robotics globally.

Product Description

SOYA NEMA 11 Integrated Stepper Motor Series

Minimize machine real estate and eliminate external driver wiring with the ultra-compact SOYA NEMA 11 series integrated stepper motor. Featuring a miniature 28mm square frame size, this intelligent actuator integrates a digital driver and a 1000-line incremental optical encoder directly onto the motor. Supporting flexible dual-mode control via traditional Pulse trains or standard MODBUS-485 commands, it features multi-level software tunability and comprehensive error guard rails to deliver reliable, zero-step-loss execution inside confined precision enclosures.

Key Performance Features

▶ Space-Saving Driver Integration

Onboard miniature digital drive bypasses complex panel rack layout wiring, drastically lowering layout clutter and signal interference paths.

▶ Smart Dual-Control Mode

Native support for traditional step pulse logic or industrial MODBUS-485 network commands to allow versatile multi-axis bus networking.

▶ High-Resolution 1000-Wire Encoder

Tracks position loop variants via a built-in optical encoder tracking network, eliminating step losses even at high-speed cycles up to 3000 RPM.

▶ Full Hardware Protection

Onboard monitoring guards electronics instantly against overvoltage, undervoltage, overcurrent, open windings, and positional deviation.

Typical Applications

Medical Laboratory Instruments Compact Pipetting Channels Handheld Medical Testers Micro Robotic Mechanisms Confined Desktop Automation
