NEMA 34 Integrated Stepper Servo Motor with Built-in Driver

SOYA NEMA 34 (86mm) Heavy-Duty Integrated Stepper Motor with Drive Series

The SOYA NEMA 34 (86mm) integrated stepper motor series is a heavy-duty, industrial-grade intelligent motion control actuator lineup engineered by SoyaMotor. Developed for high-load industrial automation requiring massive driving forces and decentralized control panel design, this 86mm square smart motor natively integrates a high-voltage digital drive and a 1000-line incremental optical encoder directly onto the motor frame. Supporting dual control methods via traditional Pulse+Direction or standard MODBUS-485 network commands, it delivers a massive torque range up to 12.5N.m and speed capabilities up to 3000 RPM under a highly versatile 18-60VAC or 24-80VDC voltage input. Built upon our own factory floor, this advanced series completely eliminates complex external driver wiring layouts, providing zero-step-loss positioning stability and comprehensive built-in protections for heavy CNC routers, automated industrial packaging lines, plasma cutting beds, and heavy-duty industrial robotics globally.

Product Description

SOYA NEMA 34 Integrated Stepper Motor Series

Optimize your heavy-duty industrial automation layouts and completely eliminate external driver panel space constraints with the flagpole SOYA NEMA 34 series integrated stepper motor. Featuring a standard 86mm square frame size with robust torque options up to a massive 12.5N.m, this intelligent actuator integrates a high-voltage digital drive and a 1000-line incremental optical encoder directly onto the motor chassis. Supporting flexible dual-mode control via traditional Pulse trains or standard MODBUS-485 bus network commands, it features wide AC 18-60V / DC 24-80V voltage tolerance, multi-level software tunability, and comprehensive error guard rails to deliver reliable, zero-step-loss heavy torque execution.

Key Performance Features

▶ Heavy Decentralized Integration

Onboard high-voltage digital drive completely bypasses external electrical cabinet layouts, drastically reducing structural wiring clutter and signal noise path lines.

▶ Smart Bus Network Control

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

▶ High-Resolution Position Loop

Tracks position loop variants via a built-in optical encoder tracking network, eliminating step losses even under rapid acceleration peaks up to 3000 RPM.

▶ Flexible AC/DC Power Input

Supports broad ranges spanning 18-60VAC or 24-80VDC inputs to handle volatile reverse EMF voltage spikes with uncompromising dynamic torque.

Typical Applications

Heavy CNC Gantry Routers Industrial Packaging Lines Plasma Cutting MachineryCenter Heavy-Duty Linear Actuators Material Handling Automation
