Abstract
PURPOSE: To minimize the heat transmission to the bearing member and extend the life of the bearing by means of a cylindrical member provided between the stator core and the bearing member to increase the heat resistance thereof with respect to the cylindrical member.
CONSTITUTION: A supporting member 5 of an outer rotor motor which is adapted to guide the stator core 3 to the circumference of the cylindrical support member 5 and support the bearing 6 inside is made of an aluminum dicast while the bearing 6 is made of an ferrous oil-containing sintered alloy or the like with a larger heat resistance than aluminum. In addition, a radial groove section 15 is provided on the circumference of the bearing 6. With such an arrangement, less transmission of heat generated in the stator 1 increases the proportion of heat transmitted to the mount section 14 from the supporting member 5. As a result, it is possible to lessen the reduction in the lubricant of the bearing 6 thereby extending the life of the bearing 6.
