PURPOSE: A motor unit of a driver board integrated type for a vacuum cleaner is provided to simplify structure and to improve cooling efficiency of a driver board by integrally forming the driver board on a main body. CONSTITUTION: A motor unit(100) of a driver board integrated type for a vacuum cleaner comprises a main housing(120), an impeller, a motor, a fan guide, an auxiliary cap(160), and a driver board(170). A main hole for radiating is formed to the upper surface of the main housing. The impeller is installed in the main housing to inhale air through an inlet hole of the main housing. The motor is installed inside the main housing to rotate the impeller. The fan guide is installed inside the main housing to guide the air flowing through the impeller into an inner space. The auxiliary cap is connected to an upper part of the main housing and a lower part facing the main hole for radiating is opened. A driver driving the motor inside the auxiliary cap is mounted on the driver board. |
