Abstract

The energy density and output power of the motor or generator are maximised with improved efficiency and linear speed-torque characteristics at either low or high frequencies of operation. The permanent magnet and core are separated from each other by a gap of predetermined size. The magnet, core and gap form a magnetic circuit in which the magnet is operated at predetermined magnetic flux and field intensities. The magnet has a predetermined max. energy product which occurs at a flux density lower than its predetermined remanent flux density. The size of the gap is selected to obtain corresp. predetermined flux and field intensities which maximise the energy product. The magnet is operated in the vicinity of the max. energy product during the relative motion. (Provisional Basic advised week 8405)
