Product Detail

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 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.
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 Wolong WD100 series high performance vector inverter.The motor supporting digital services, will be the motor and drive data
collection, uploaded to Shun Zhiyun (iMotorLinx) industrial Internet platform, to achieve remote control of the system, state
Monitoring and troubleshooting.

Motor technology advantages

Advantage of WE platform

• WEPM series motors inherit the innovative features of the WE induction motor series uniformly designed by Wolong, with simple and elegant appearance, outstanding texture, high recognition and perfect combination of appearance and function.
• The shape of the terminal box with hexagonal elements increases the internal space and makes the electrical safety performance more reliable.
• H180 and below frame size can provide top lifting ring or horizontal side lifting ring; H200 and above frame size adopts double lifting ring, with high safety coefficient and large lifting margin;
• Adopting the optimal design of the blade and chassis taper, the overall optimization and simulation design of the cooling air circuit composed of the wind cover to realize the optimization of the cooling effect;
• The machine is compact in design, IEC standard in size, high interchange ability and flexible in outlet;
Lower noise
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).
High power density advantage - Low volume and reduced weight
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.
Maintain constant torque in a wide range of speed regulation
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.
