Frameless motor is a high-performance, compact motor consisting only of a rotor and stator, designed to be integrated directly into machinery, eliminating the housing, bearings, and shaft of traditional motors
Ultra-Compact Design (Open Type): Without an outer shell or bearings, these motors save critical space and weight, allowing for seamless mechanical integration.
High Torque Density: Multi-pole design (14 to 20 poles) delivers exceptional peak and continuous torque at low speeds.
Direct Drive Precision: Eliminates the need for traditional mechanical transmissions in many setups, resulting in zero backlash, increased stiffness, and faster dynamic response.
Advanced Sensing: Available with optional Hall effect sensors and PTC thermistors for accurate position feedback and thermal protection.
Excellent Thermal Dissipation: Class F and Class H insulation options ensure reliable operation even under demanding continuous loads.
Robotics: Robotic arm joints, humanoid robots, and collaborative robots (Cobots).
Industrial Automation: CNC rotary tables, automated guided vehicles (AGVs), and custom planetary gearbox integrations.
Medical Equipment: Surgical robots, exoskeletons, and precision scanning devices.
Aerospace & Defense: Gimbal systems, radar drives, and unmanned aerial vehicles (UAVs).
