PCT No. PCT/CH84/00119 Sec. 371 Date Mar. 28, 1985 Sec. 102(e) Date Mar. 28, 1985 PCT Filed Jul. 30, 1984 PCT Pub. No. WO85/00705 PCT Pub. Date Feb. 14, 1985.A multiphase motor including a facially magnetized rotor having N/2 pairs of poles per face. The motor also includes a stator for each phase. Each stator has a first and second pair of polar pieces, each pair of polar pieces including internal and external substantially coplanar polar pieces interpositioned one within the other. The internal stator pieces of one phase of the motor are constructed with fractional stator poles, whereas all remaining stator poles are full. Each phase includes a core piece which has a first end connected to the internal polar pieces, and a second end connected to external polar pieces. Each core of each phase has a coil wound thereon. A motor constructed according to the invention prevents loss no magnetic flux from the magnetized rotor. This allows the motor to be highly energy efficient, and compact in size.
