Protection structure of motor for cooling-fan

Abstract

A protection structure of a motor for a cooling fan include a motor to which power source wire is connected for receiving electricity and a hub that is coupled to the motor and rotates. The hub includes: an outer portion along an outer peripheral surface of which blades are formed and on a center of which a center hole is formed; a center portion which is disposed at a middle of the center hole and to which is a rotations shaft of the motor is coupled; and a support member that couples the outer portion and the center portion. The support member is fractured physically to prevent overload to the motor and fire in advance. Furthermore, the power source wire is configured via the support member and thus is broken together when the support member is fractured to prevent unnecessary rotation of the motor.

Dependencies are inferred from the claim text.
