Description
technical field [0001] The invention relates to a novel low-speed high-torque direct-drive compound motor device based on magnetic gears, belonging to the technical field of magnetic gear transmission systems. Background technique [0002] In some occasions of low-speed movement in industrial production, since the motor speed is often high, it is often connected through a mechanical gearbox to achieve low-speed and high-torque operation. However, the gearbox greatly increases the volume and weight of the entire transmission system, and the investment cost also increased accordingly. In addition, there are other problems such as high noise, low efficiency, low transmission accuracy, slow response, and mechanical wear. Magnetic gear is a new type of gear structure. It has the advantages of low noise, maintenance-free, high reliability, large torque transmission capacity, overload protection, etc. It is integrated with a permanent magnet brushless motor to form a composite mot...
