The WEPM series is a permanent magnet product designed and developed by Wolong globally. The motor features a rotor with permanent magnets and has higher efficiency and power density than induction motors.

Description

The wolong brook brand WEPM series permanent magnet motor has a smaller frame size with the same power and torque output, and the energy efficiency level complies with IE4~IE5 efficiency. It has the ability to weaken the field and speed up, can run at overspeed, has a wide speed range, and has significant energy saving effects. . It has the characteristics of beautiful appearance, high efficiency, low noise, low vibration, safety and reliability, and easy maintenance. Suitable for applications with strict requirements on speed regulation, low-speed precise control, low noise and compact design. It can be widely used in water pumps, fans, air compressors, machine tools, reducers, etc.

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.
