WEPM series variable frequency speed-regulating permanent magnet synchronous motor are ultra-efficient permanent magnet motors. They are designed with rare earth permanent magnet materials and their efficiency conforms IE5 to IE4 grade.
It has higher efficiency and power density than the induction motor, and the frame size of the same power and torque output motor is smaller.
The series motors are featured by beautiful appearance, high efficiency, low noise, low vibration, safety and reliability, and easy maintenance. Widely used in pumps, fans, air compressors, machine tools, reducers, packaging machinery, mining machinery, construction machinery and other types of transmission machinery industry.
WEPM series variable frequency speed-regulating permanent magnet synchronous motors can be matched with multiple brands of universal frequency converters. After long-term experiment, it has the best performance when matched with WD100 series high performance vector inverter.
The motor adopts self-fan cooling design, can be driven in the frequency converter speed regulation operation without forced ventilation and cooling. It has low speed constant torque operation ability, wide speed range, high efficiency features with a full range. The mounting size of each frame is consistent with the induction motor, and in line with IEC and relevant national standards, convenient for customers to install and use.
Advantage of WE platform
Compared with the induction motor, WEPM motor significantly reduces the loss, so the cooling fan used is smaller, which significantly reduces the noise of the motor, and the noise reduction effect can be up to 15 dB(A).
Permanent magnet synchronous motor with IE4&IE5 efficiency,compared with the same power and speed induction motor (IE3), the volume is reduced by 1-2 frame size, not only improve the motor efficiency, but also reduce the motor weight and volume. WEPM motors have shafts and bearings that can withstand higher power and torque in a smaller housing size.
The motors can operate at constant torque over a wide range of rotational speeds, no need for forced ventilation. This feature makes it an ideal choice for applications that require variable speed and constant torque, even at low speeds, without the need for an encoder.
