3kv Permanent Magnet Synchronous Motor 60 Poles 400-15000kw

Permanent magnet synchronous motors (PMSMs) utilize permanent magnets to provide the magnetic field required for electromechanical energy conversion, eliminating the need for an excitation power supply. During synchronous operation, the rotor carries almost no current, resulting in negligible rotor copper losses and a significantly improved power factor compared to asynchronous motors.

Key advantages of our PMSM motors include:

• Synchronous operation eliminates speed fluctuations, preventing additional pipeline resistance losses when driving fan or pump loads
• High starting torque and overload capacity can be designed, addressing the issue of "oversized motors for light loads"
• Wide high-efficiency operating range: within a load range of 25%-120%, efficiency remains above 85% and power factor exceeds 0.9
• High power factor improves grid power quality, eliminating the need for reactive power compensation devices
• When paired with variable-frequency drive systems, PMSMs offer better dynamic response than asynchronous motors
• Higher power density: for the same power and speed, PMSMs can reduce the frame size by at least one level
• Diverse topological structures enable customized solutions for a wide range of applications
