A bearing unit for a drive motor, which is installed between a motor housing and a rotating shaft, includes: a bearing having two or more support bumps formed on the outer circumferential surface of an outer ring, and installed between the front or rear of the rotating shaft and the motor housing so as to rotatably support the rotating shaft with respect to the motor housing; and a bearing cover assembled to the motor housing, having a circular stepped surface formed on one surface such that an outer ring of the bearing is fitted to the stepped surface and supported in an axial direction. In particular, a support portion is formed on the stepped surface and is in contact with the support bumps so as to fix the outer ring in a rotation direction.

Bearing unit for drive motor

Disclosed herein is a method and a system for controlling a generation output of a starter generator connected to an engine to transmit a rotary force in a hybrid electric vehicle. The method includes receiving, by a controller, vehicle state information for determining a driving mode of the vehicle after the vehicle starts, and determines the driving mode requiring an increase of the generation output from the vehicle state information; determining, by the controller, a need for the increase of the generation output to control a generation output variable for each driving mode; determining, by the controller, a torque command and a torque application time corresponding to a required output for each driving mode of the vehicle to control the generation output variable; and applying, by the controller, the determined torque command for the determined application time to control the generation output of the starter generator.
