MDB Series Frameless Torque Motors

1. Product Introduction The MDB series frameless torque motor is a high-performance drive component specially designed for full-scenario adaptation of humanoid robots. It covers a full range of frame sizes from φ14mm to φ160mm and a rated torque range of 0.012Nm to 12Nm providing a variety of standard models that can accurately match the full-size joint requirements of humanoid robots from dexterous hands to hip joints. With optimized magnetic circuit design structural design and heat dissipation design the product integrates advantages such as high torque density fast dynamic response and low jitter noise. It can adapt to complex working conditions such as high burst high precision and high transient load ensure long-term stable operation and provide reliable power support for robot joint movement. 2. Product Highlights ①Excellent Magnetic Circuit Utilization: The maximum split ratio of the stator core reaches 0.72 which greatly optimizes the magnetic circuit layout significantly improves torque density and dynamic response capability and meets the requirements of high-burst and high-precision control scenarios. ②Strong Overload Capacity: Supports 3.5 times instantaneous overload with sufficient short-term peak torque output which can easily cope with high-transient load conditions such as robot dynamic gait and rapid start-stop. ③Ultra-Fast Response Speed: Optimized rotor structure design results in extremely low moment of inertia. Combined with high-bandwidth control it achieves millisecond-level response effectively improving the accuracy and stability of joint motion control. ④Stable and Quiet Operation: Low cogging torque characteristics can effectively suppress low-speed jitter and operating noise ensure motion smoothness and improve trajectory tracking accuracy. ⑤Efficient Stable and Durable: Adopts efficient heat dissipation design with low temperature rise which can ensure long-term stable operation extend motor service life and adapt to high-load cycle conditions; at the same time it has ultra-high torque density to meet the needs of lightweight and high-output scenarios. 3. Main Application Industries It is mainly applied in the humanoid robot industry and can also be extended to high-end equipment manufacturing industries such as industrial robots and collaborative robots. It is suitable for scenarios with strict requirements on motor torque density response speed and operation stability and provides core component support for joint drive of various intelligent robots.
