DYT permanent magnet low speed direct drive motor
Change and Innovation of Driving System
National Engineering Research Center of Rare Earth Permanent Magnet Motor
With the rapid development of industrial automation, new and higher requirements are put forward for different types of electric drive systems, including improving reliability, reducing power consumption, reducing maintenance costs and meeting the complex requirements of industrial processes.
With the development of magnetic material technology, power electronics technology. With the development of microcomputer technology and control theory, permanent magnet motor is more and more widely used for its high torque-to-inertia ratio, high energy density and high efficiency. In particular, the development of servo control technology with vector control technology and direct torque control technology as the core makes a revolutionary product of low speed and high torque-permanent magnet direct drive motor system emerge as the times require. Compared with the traditional drive system, it removes the intermediate transmission transition link and realizes the direct connection between the permanent magnet direct drive motor and the load end.
