24 V torque motor HPJM-RE50-60-PRO-XX

48 Vhollow-shaftframeless

Introduction
The PRO Series Robot Joint Motor integrates a harmonic drive, frameless torque motor, brake, dual encoders and an embedded drive unit into an optimized package to deliver high torque density, precise motion and a compact form factor. Typical supply voltage range: DC 24V–48V. Customization services are available for protocol, brake and low-temperature operation. Primary applications include robot joints (wrists, heads), humanoid robots, semiconductor equipment, PV equipment, precision medical devices, 3C and optical instruments.

Core Components

• Power unit (frameless torque motor): high torque density and compact integration for dynamic-load scenarios.
• Harmonic drive: speed reduction and torque multiplication with near-zero backlash (controlled within 20 arcsec).
• Dual encoders (motor-side & output-side): enable full closed-loop control with repeat positioning accuracy of ±10 arcsec.
• Temperature sensor: real-time monitoring of load and environment.
• Embedded drive unit: supports EtherCAT and CANopen, enabling dynamic PID and fieldbus integration.

Features

• Superior precision & zero backlash
  • Zero-backlash harmonic design eliminates transmission clearance of conventional reducers; repeatability ±10 arcsec, absolute positioning ±30 arcsec — suitable for surgical robots and collaborative manipulators.
  • 3D conjugate dual-arc tooth profile reduces vibration and noise, increases stiffness and service life.
• Highly integrated, compact and lightweight
  • Integrated harmonic drive and frameless motor provide a compact envelope for space-constrained joints (wrists, necks).
  • Use of high-strength aluminum alloys and carbon-fiber components reduces weight and improves energy efficiency.
• High transmission efficiency
  • Transmission efficiency exceeds 80%, minimizing energy loss under dynamic loads.
• High safety and reliability
  • Optional torque-sensor integration supports collision detection and drag-teaching.
  • Designed to withstand impact and emergency stops; precision life >10,000 hours in typical industrial use.
• Intelligent integration and control
  • Embedded controller with multi-protocol support (EtherCAT, CANopen) and modular interfaces for rapid integration and maintenance.
