Abstract
A motor includes a holder having an annular plate shape with a plate thickness in an axial direction of a rotor housing, and including a flange section disposed so the rotor housing rotates at an inner side of the flange section, a center piece including a plate-shaped section opposing the flange section, and a heat sink including a heat dissipation section projecting from the plate-shaped section toward the flange section. The flange section integrates with a flow rectification section including a cooling air flow rectification face extending along a cooling air flow path between the flange section and the plate-shaped section. The heat dissipation section is disposed in the cooling air flow path. The cooling air flow rectification face closely opposes the top of the heat dissipation section. A bulk reduction section is between the cooling air flow rectification face and the flange section opposite of the plate-shaped section.
