    摘要: In the magnet retention channel arrangement for a high speed rotor described in the specification, a rotor has an array of radially projecting, angularly spaced pole pieces and a magnet retention channel member inserted between each adjacent pair of pole pieces. Each magnet retention channel member is made of nonmagnetic material and has opposed side walls and an integral end wall at one end of the side walls and integral dovetail feet at the opposite ends of side walls. The channels contain permanent magnets and the side walls of uniform thickness with nonmagnetic feet within the core member couple the magnetic flux from the magnets to the pole pieces with substantially no magnetic discontinuities while the presence of the nonmagnetic end wall avoids magnetic shorting.

    摘要: In the magnet retention channel arrangement for a high speed rotor described in the specification, a rotor has an array of radially projecting, angularly spaced pole pieces and a magnet retention channel arrangement inserted between each adjacent pair of pole pieces. Each magnet retention channel arrangement has ferromagnetic side walls and a nonmagnetic alloy cap and nonmagnetic alloy dovetail feet affixed to opposite edges of the ferromagnetic side walls by welding or by a hot isostatic pressed powder metallurgy technique. The channels contain permanent magnets and the ferromagnetic side walls couple the flux from the magnets to the pole pieces with substantially no magnetic discontinuities and the nonmagnetic alloy cap and nonmagnetic core avoids magnetic shorting.
