IntroductionHONPINE FM1 frameless Brushless DC (BLDC) motors are compact, high-performance industrial actuators provided in multiple size variants. Available sizes cover approximately φ50 mm to φ115 mm. Rated voltages range from 24 V to 70 V; optional Hall sensors, temperature sensors and wiring configurations are available. Typical uses include collaborative robots, humanoid robots, quadrupeds and medical rehabilitation equipment.
Features- High torque density: torque increases by approximately 10% at the same input current.
- Extended endurance: optimized magnetic circuits and material selection reduce motor losses and extend operating time.
- Compact frameless structure: removal of housing and redundant components reduces volume by ~40–50% versus standard housed motors, simplifying embedding in tight layouts.
- Low inertia: lightweight design and application of composite materials enable fast dynamic response for frequent start/stop cycles.
- Low temperature rise: magnetic circuit optimization reduces losses by ~20%, improving conversion efficiency.
- Integration-friendly: frameless form factor supports flexible installation and direct mechanical integration into custom gearheads or joints.
Applications- Collaborative robots (cobots)
- Humanoid robot joints
- Quadruped robots
- Medical rehabilitation robots and actuators
