Hermetically outer rotor motor for outdoor unit of airconditioner

A sealed outer rotor type motor for an outdoor unit of an air conditioner is provided to improve the safety of an outer rotor type motor by preventing an external foreign substance from permeating into the inside. A sealed outer rotor type motor for an outdoor unit of an air conditioner includes a housing(10,20), a stator(30), a rotor(40), a rotation axis(50), and at least one heat block(61). The housing is installed inside an outdoor unit for an air conditioner, and has a sealed inner space. The stator is fixedly installed on the inner space of the housing. The rotor is rotatably arranged on the outer circumference plane of the stator, and is installed on the inner space of the housing. The rotation axis is coupled to a center of the rotor and transfers a rotation force. The heat block conducts a heat generated from the stator and discharges the heat to an external part of the housing. An outer circumference plane of the heat block is closely adhered to the inner circumference plane of the stator. A bottom plane of the heat block is closely adhered to the inner plane of the housing.
