Frequently Asked Questions
What are the main advantages of the WEPM series PMSM intermittent motor?
The WEPM series motor features a beautiful appearance, high efficiency (supporting IE4 and IE5 efficiency classes), low noise, low vibration, safety and reliability, easy maintenance, and excellent PMSM efficiency performance.
What applications are these PMSM motors suitable for?
They can be widely used in various transmission machinery industries such as water pumps, fans, air compressors, machine tools, reducers, packaging machinery, mining machinery, construction machinery, and PMSM motors for compressors.
What are the differences in frame sizes and power ratings between Cast Aluminum and Cast Iron models?
The Cast Aluminum model offers frame sizes from H56 to H160 with a rated power of 0.25 to 55kW. The Cast Iron model supports larger sizes from H132 to H315 with a rated power ranging from 7.5 to 315kW.
What insulation and protection ratings do these motors feature?
Both versions use Class F (△ T 80K) or Class H nano insulation. They feature a service factor of > 1.0 and offer high protection classes including IP55, IP56, IP65, and IP66.
What are the lubrication requirements for the bearings?
The Cast Aluminum motor uses maintenance-free bearings. For the Cast Iron motor, sizes H180 and below use maintenance-free bearings, while sizes H200 and above use open bearings equipped with an oil filling device.
