Variable flux permanent magnet machines represent a dynamic class of electrical machines in which the air-gap magnetic flux can be actively adjusted during operation. This flexibility permits improved ...

Since the boom of the NdFeB magnets industry, the usage and potential applications for permanent magnet machines have grown exponentially to the detriment of traditional induction systems. In special ...

The global price of energy is at an all-time high, with few signs of relief in sight, making consumers and businesses alike interested in energy conservation. Currently, the most common motor type in ...

The Ecoheart family of high-efficiency permanent-magnet motors and drives achieve 10% higher efficiency because internal power loss is reduced by 50%. The high-performance magnets and a new method for ...

The high-energy-product neodymium rare-earth permanent magnet (RE-PM) was discovered in the early 1980s. Later, dysprosium doping emerged to provide reasonable RE-PM magnetization life by sacrificing ...

With an outstanding track record for innovation and successful commercialisation the Electrical Machines and Drives group is known for its pioneering research on permanent magnet machines and drives ...
