BURIED PERMANENT MAGNET ROTATOR

摘要

PURPOSE: A buried permanent magnet rotator is provided to minimize a leakage magnetic flux and to maximize a valid gap flux contributing an output of a motor. CONSTITUTION: Upper and lower covers(31,34) are mode of a nonmagnetic body and are disposed at upper and lower parts. The upper and lower covers have the same shape and an opposite structure. A plurality of yoke blocks(32) have both ends supported at an outer part on the same circumference of the upper and lower covers. The yoke blocks correspond to magnetic poles, respectively. A plurality of disk-type permanent magnets(33) are inserted between the yoke blocks and correspond to magnetic poles supported by the yoke blocks and the lower and upper covers. A rotary shaft(35) is connected with a penetration hole which is formed at a center portion of the upper and lower covers.
