摘要： A synchronized induction motor comprises a stator including a cylindrical armature core having an armature winding wound thereon for generating a rotating magnetic field, a cylindrical housing for housing the stator therein, end brackets mounted at opposite open ends of the housing and having a bearing mounted at a center portion thereof a rotor shaft concentrically arranged in the stator axially of the armature core and rotatably supported by bearings, a rotor core mounted concentrically with the rotor shaft on the rotor shaft and magnetically coupled to the armature core through an air gap, end plates mounted to sandwich the rotor core, starting secondary conductors arranged axially of the rotor shaft in the vicinity of an outer circumference of the rotor core and adapted to cooperate with the stator which is held by the end plate to form an induction motor, end rings for shorting the ends of the secondary conductors on the end plates, balance rings mounted on the rotor shaft in the vicinity of the bearings, sumarium-cobalt split-type permanent magnets arranged around the outer circumference of the rotor core axially of the rotor shaft, and an epoxy fiber impregnated glass fiber tape or stainless steel tape for holding the permanent magnets on the rotor core. The permanent magnets are magnetized after they have been mounted on the rotor core.
