Permanent magnet synchronous direct drive motor integrates variable frequency vector, permanent magnet direct drive, micro-electronic control and other technologies to remove the traditional deceleration device, connect with the load rotation shaft, and directly drive the load, so that the transmission system structure is simplified, efficiency is improved, noise is reduced, easy installation, no manual daily maintenance and repair, thus saving a lot of manpower and material costs. It reduces the environmental pollution in the production process and effectively reduces carbon emissions.
