Permanent Magnets

The WMagnet utilises powerful permanent magnets made from a combination of neodymium, iron and boron (NdFeB), and commonly referred to as rare-earths magnets. These magnets are some eighteen times stronger than traditional Ferrite Magnets. In order to provide superior mechanical strength and corrosion resistance, the Neodymium/Iron/Boron magnets are covered with a protective epoxy coating.

Thermal Protection

WMagnet motors have PTC (Positive Temperature Coefficient) thermistors embedded in their windings which offer full protection against overheating produced by phase loss, overload and under or overvoltage.

Endshields / Lubrication

The WMagnet motors are equipped with bearings offering an L10 life of up to 100,000 hours. All motors feature open bearings and endshields with grease nipples which permit re-lubrication lubrication and consequently a reduction in stoppages for maintenance.

Bearings

As WMagnet motors are supplied with long-life bearings, the maximum permissible radial loads differ from those of general purpose induction motors, as shown in the following table. Axial loads are as per W22 general purpose induction motors on horizontal application. For vertical application, please consult WEG.
