摘要

The electromotor (10) has a stator, which generates by supplying a current for a coil of rotating magnetic field. Permanent magnets (30) are placed in the slots. The periphery slot segments have smaller width than the radial slot segments. The permanent magnets are placed only in the periphery of slot segment, in such way that same periphery slot segments contain permanent magnets in areas near the edges. A cylindrical rotor (14) rotates synchronously with the rotating magnetic field at many partial magnet paths (22), which are divided by several slots (20) into strips. The adjacent magnet poles are formed to interconnect in order to arrange magnet poles at the periphery of the rotor.
