Kind Code:

Abstract:
An end bracket for a motor comprising an inner wall and an outer wall. The inner wall is formed from a thin magnetic shielding material and the outer wall is formed from a non-magnetic material. The inner wall comprises: a larger-diameter cylindrical part having an outside diameter substantially equal to that of the stator core of a motor and further having an inner end in contact with said stator core; a smaller-diameter cylindrical part coaxial with the larger-diameter cylindrical part and having an outside diameter substantially equal to that of the rotor of the motor and further having an inner end facing said rotor across a gap; and an end disk part integrally connected to the outer ends of these cylindrical parts respectively. A plurality of small projections are formed on the end disk part of the magnetic shield to project in the opposite direction to the cylindrical parts so that the height of each of the small projections is substantially equal to the thickness of the outer wall of non-magnetic material, and the small projections are buried in said outer wall in order to connect the magnetic shield and the outer wall into a unitary end bracket.
