Abstract
PURPOSE: To prevent cocking and to expand the range of stable-rotation voltages by arranging a disc-shaped rotor so as to oppose face to face against the magnetic- pole teeth of a stator; and by providing an arc-shaped magnet, which has a length of three magnetic poles of the rotor and whose top and bottom are magnetized, at the location adjacent to the rotor.
CONSTITUTION: Multiple-magnetic-pole teeth 2 are formed on the top of a stator 1 which is bent in a U-shape so as to surround a stator coil 13 of a motor, and a disc- shaped permanent magnet rotor 3 is arranged so that it opposes face to face against the magnetic pole teeth 2. At an edge portion 17 of said stator 1, is provided an arc-shaped permanent magnet 10 which has a length corresponds to the three magnetic poles of said rotor 3 and is magnetized in the up-and-down direction. The permanent magnet 10 opposes the rotor 3, but is higher than the rotor 3 by 1mm or more. In this constitution, even though the mechanical loss of the shaft 8 is degraded especially in the case the length of the gap is long or in the high-temperature atmosphere, a magnetic brake can be actuated by the linkage of the magnetic fluxes of the arc-shaped magnet and the magnetic fluxes of the rotor, thereby the cocking can be prevented.
