Magnet protection mechanism for magnet body in rotor and magnet protection method
InactiveUS7784168B2Simple wayProtective AdhesionMagnetic circuit rotating partsManufacturing stator/rotor bodiesAlternatorProtection mechanism
A magnet covering member made of a soft steel plate covers an outer surface of a magnetized permanent magnet placed in a rotor core of a rotor. The magnet covering member is detached from the permanent magnet when the rotor is incorporated into a stator of an alternator during an alternator assembling process. Because of a soft magnetic characteristic of the magnet covering member, an outer magnetic field generated by the permanent magnet placed between adjacent claw poles of the rotor core makes a magnetic short-circuit, and a magnetic attracting phenomenon caused by such a magnetic field is thereby reduced. The soft magnetic characteristic of the magnet covering member also serves to support the rotor.
