    Permanent Magnet Machines


    Rare earth based PM machines are the present work horse in industry where high power density and/or efficiency are required. We have done our share of development in this area, and have a range of designs available. Our extensive experience with rare earth machines gives us the engineering depth to attempt even challenging designs and topologies.
