STRUCTURE OF INSTALLING PERMANENT MAGNET IN MOTOR

摘要

PURPOSE: An installation structure for a permanent magnetic of a motor is provided to supply a high efficiency electric motor by accurately controlling the location of the inner wall of the permanent magnet. CONSTITUTION: A casing(110) is made of metal materials in the shape of a circular pipe. The casing includes a protrusion(111p). The protrusion is projected to the inner surface at intervals of the predetermined angle of circumference. Permanent magnets(120) are installed on the inner wall of the casing. A position fixing spacer(130) is made of a metal plate.
