Intelligent permanent magnet direct drive system is a comprehensive solution for equipment drive and control technology. VFD synchronous motor takes permanent magnet direct drive technology as the core and adopts special frequency converter, permanent magnet synchronous frequency conversion motor, and water cooler to replace traditional mechanical drive devices such as asynchronous motor, reducer and hydraulic coupler. At present, VFD synchronous motor is widely used in mines, coal, ports, electric power, building materials, chemical industry, and other fields.

Features of the PM Motor with Integrated VFD
The VFD synchronous motor has the characteristics of high VFD motor efficiency, energy-saving, large starting torque, excellent performance, small maintenance, and intelligent drive.
High efficiency and energy saving
The intermediate transmission link of the vfd synchronous motor is omitted, and the load is directly driven.
No rotor excitation, no rotor copper loss, high rated efficiency.
The light load area has excellent efficiency and high operation efficiency of the motor with integrated VFD.
Even VFD synchronous motor is at 0 speed, there is a relatively large torque
Heavy-duty starting: starting torque up to 2 times rated torque.
Smooth start to reduce the mechanical impact on load equipment.
Automatic step-less speed regulation according to load, reducing power consumption and prolonging the service life of load equipment.
Motor with integrated VFD has a Small starting current, reducing the impact on the power grid and reducing power grid failures.
VFD for synchronous motor has less footprint.
With integrated VFD motor technology, you can install the equipment in the narrow space as shown in our drawing.
Qingdao CCS Electric Corporation is a professional power control equipment company, we provide electrical power transmission equipment, power control equipment and etc.
