PMM28 Integrated DC Servo Motor

17-bit absolute single-turn magnetic encoder Soft limit function SEMICONDUCTOR INDUSTRY PRECISION MACHINING NEW ENERGY INDUSTRY The PMM28 series of integrated low-voltage servo motors is a compact integrated servo motor product independently developed by our compa- ny. This product is based on a highly integrated one-piece development concept, integrating permanent magnet synchronous motors, 17-bit absolute single-turn encoders, servo drives, controllers and digital I/O. It can be widely applied to various small and medium-sized automa- tion equipment. The PMM28 series of integrated servo motors adopt a highly integrated design, perfectly blending permanent magnet synchronous motors and drive control systems.

Highly integrated design

Integrates permanent magnet synchronous motor, absolute encoder, servo drives, controllers and digital I/O into a single compact unit, so no external drive is required. Compared with conventional separated solutions it saves considerable installation space, needs less wiring, and makes commissioning and maintenance easier.

High Precision Encoder Feedback

Built-in 17-bit single-cycle absolute encoder (multi-cycle absolute counting, automatic storage of power loss) provides real-time position and speed feedback for more accurate closed-loop control; multi-turn absolute counting and automatic position storage on power loss mean no re-homing is needed after power-up.

Multi-bus communication support

Supports CANopen and RS485 communication, allowing quick connection to mainstream PLCs, motion controllers and host systems, with flexible networking and easy expansion.

Standard CiA 402 Sport Mode

Supports CiA 402 standard motion modes (PP, PV, HM, CSP, CSV, etc.) as well as position mode, velocity mode and torque mode, ensuring compatibility with mainstream fieldbus motion-control architectures and making replacement and commissioning easier.

Wide Voltage Input

Wide input voltage range of 12-30 VDC, suitable for various power-supply environments and giving greater flexibility in system integration and retrofitting.

Complete diagnosis and protection

Comprehensive diagnostics and protection covering over-voltage, under-voltage, over-temperature, stall, overload, over-speed, over-travel and homing timeout, with current and historical alarm records for safer operation.

3D Printer Equipment Applications

The PMM28 features a slim, lightweight housing that reduces overall length by approximately 30% compared to conventional split-type solutions. It fits effortlessly into tight mounting locations such as print-head lifting mechanisms, bed-leveling actuators, filament extruders, and multi-axis turntables. For desktop, portable, or modular 3D printers, this translates directly into smaller machine footprints, cleaner internal wire routing, and more efficient airflow for thermal management – all without compromising motion performance.
