ABSTRACT:
A permanent magnet electric motor comprises a body shell with a cylindrical inner face, permanent magnets lying against the inner face of the body shell, and connecting pieces, each of which has a body portion disposed between two adjacent permanent magnets. Each connecting piece also has two lugs axially adjacent to, and overlapping, end faces of the magnets. An end plate of the motor is fixed to its body shell facing towards these end faces of the magnets. The connecting pieces and the end plate are so arranged that part of the end plate faces towards the connecting pieces in the axial direction, and is adjacent to the latter. The invention is applicable in particular to motors for motor vehicles ventilating systems.
