<p>The present invention relates to a device for cooling a motor, which includes: a fan hood which has an air inlet for external air and a motor housing and an air injection hole to inject air to the outside of a motor housing; and a draft fan which supplies air to the air inlet of the fan hood and forcibly injects the air through the air inlet. The end of the injection hole of the fan hood is extended to the motor housing. Thereby, the speed of air supplied to the outside of the motor housing is increased to greatly reduce the surface temperature of the motor housing.</p> |
