Permanent magnet motors come of age
We're all well aware of the advantages of permanent magnet motors, but there's no getting away from the cost penalty in turning away from the standard 3-phase squirrel cage motor. But now a new design of PM motor from WEG promises to bring the benefits of PM motors into the mainstream.
The high efficiency WMagnet motors are designed for applications where constant torque, low vibration and low noise levels are required; typically elevators, compressors and conveyors. Because they can operate self-ventilated over a wide speed range, the motors are also ideal for use in applications where gearboxes need to be eliminated to save space.
The motors reduce size by up to 50%, weight by up to 36%, and deliver higher efficiencies (up to 97.5%) compared to equivalent size induction motors. In addition, they are, generally, at least one frame size or core length smaller.
