When every millimeter of axial space saved unlocks new design possibilities, and when humanoid robot joint modules demand the ultimate in integration – our Ultra-Thin Servo Motor Brake, with a profile down to just 12mm, opens up new horizons for precision drives and automated equipment.
Covering the full 10LE–220LE frame size range, with static torque spanning 0.02 to 40 N·m and support for custom specifications, this is not just another brake – it is a systematic answer to the four key challenges of compactness, efficiency, cleanliness, and quiet operation.
With a minimum axial thickness of only 12mm, this brake saves significant installation space compared to conventional designs. Whether in compact automation modules or the narrow cavities of humanoid robot joints and rotary actuators, it integrates effortlessly.
All models feature standardized radial and axial dimensions that precisely match standard servo motor flanges, enabling seamless assembly without additional modifications.
From micro servos to heavy-duty equipment, we have you covered:
| Series | Torque Range | Typical Applications |
|---|---|---|
| 10LE–40LE | 0.02–1.3 N·m | Micro servos, collaborative robot small joints, vision inspection equipment |
| 50LE–130LE | 3.2–6.6 N·m | Standard servo motors, CNC modules, AGV drive units |
| 150LE–220LE | 10–40 N·m | Heavy-duty automation, machine tool spindles, large robot joints |
Torque, mounting dimensions, and voltage can all be customized to meet diverse project requirements.
Our dual-coil over-excitation control applies a high voltage during engagement for rapid braking, then switches to a low voltage for steady-state holding, dramatically reducing long-term power consumption.
Class F coil insulation ensures stable performance even at elevated temperatures
Withstands high speeds up to 6000 r/min with reliable braking response
Low heat generation, ideal for continuous operation
Dust shedding and brake squeal have long plagued high-precision equipment users. Our in-house formulated friction material fundamentally eliminates dust generation and abnormal noise. With a maximum single braking energy of 2000 J and extended wear life, it is built for long-term, high-accuracy continuous operation.
