Abstract
A motor includes a support member having a bearing housing defining a bearing hole therein, a stator assembly mounted to an outer periphery of the support member, and a rotor assembly having a rotary shaft extending into the bearing hole and a permanent magnet confronting the stator assembly. A bearing pattern is formed on either of the bearing housing and the rotary shaft. The bearing pattern includes a number of first and second grooves arranged circumferentially in an alternate fashion. Each of the first grooves is in communication with one adjacent second groove at an edge of the bearing pattern. Lubricating oil is filled in the bearing pattern to establish dynamic pressure to separate the shaft and the bearing sleeve in radial direction when the shaft rotates.
