A decade ago, Kinco pioneered frameless torque motor technology for robotics. Today, the FMK series represents our fourth-generation innovation, featuring an optimized stator welding process, improved stator roundness, and a minimized axial length—all while delivering superior performance to meet diverse customer requirements.
Features
- High torque density – Optimized motor electromagnetic design, lightweight harmonic gearing and structural components, and a reduced drive footprint maximize the joint module’s torque density.
- High rotational speed – Supports speeds up to 50 rpm
- Modular and highly integrated design – Fewer parts, lower overall weight, and improved reliability.
- Precise thermal management – Equipped with low-latency, high-accuracy temperature sensors for real-time motor temperature monitoring and over-temperature protection.
- Available outer diameters – 55 mm, 60 mm, 70 mm, and 80 mm (custom options available).
iFMH rotary joint modules are widely used in
Industrial Production, Security Patrol, Delivery Service, Guided Tours
