PURPOSE: An electric vehicle motor cooling apparatus is provided to have a control unit which drives an air suction fan according to the temperature of the housing of an electric vehicle motor, thereby efficiently cooling the electric vehicle motor. CONSTITUTION: An electric vehicle motor cooling apparatus includes a motor housing(10), an air inserting tube(12), an air discharging tube(14), and an air suction fan(16). The air inserting tube is connected to one side of a motor. The air discharging tube is connected to the other side of the motor to discharge air inserted into the housing to the outside. A control device applies a control signal to the air suction fan according to a temperature sensed by a sensor device(24). |
