Abstract: An integrated motor drive includes a frame assembly, a motor, a motor driver and a heat dissipation assembly. The frame assembly includes a first frame and a second frame. The motor is installed on the first frame. The motor driver is installed on the second frame. The heat dissipation assembly includes a motor heat exchange pipe, a motor driver heat exchange pipe, and a heat dissipation pipe. The motor heat exchange pipe is embedded in the first frame, and located at one side portion of the motor for performing heat exchange with the motor. The motor driver heat exchange pipe is embedded in the second frame for performing heat exchange with the motor driver. The heat dissipation pipe is located at an end portion of the motor, and communicated with the motor heat exchange pipe and the motor driver heat exchange pipe.

Abstract: A motor sleeve is applied to a motor housing and a motor driver housing. The motor sleeve includes a sleeve base, a second fixing structure, a second coupling structure, a plurality of base fins, a sleeve chassis, a plurality of chassis fins, and a third fixing structure. The second fixing structure is disposed on an inner surface of the sleeve base and correspondingly fixed to a first fixing structure of the motor housing. The sleeve base is installed on a lateral portion of the motor housing. The base fins are separately disposed on an outer surface of the sleeve base and corresponding to a first coupling structure of the motor driver housing. The motor driver housing is coupled to the sleeve base by the first and second coupling structures. The third fixing structure is correspondingly fixed to a fourth fixing structure of the motor housing.

Abstract: A hand dryer device cooperated with an airflow driver includes a first housing, a second housing, and an airflow driving unit. The first housing has a first body and a first extension portion. The second housing has a second body and a second extension portion. The second body is connected to the first body for defining an accommodating space, and the first and second extension portions together form a concave annular structure having an extension space. The airflow driving unit includes a sensor, a control module and an airflow guiding structure. The sensor is disposed on the outer surface of the first housing and/or the second housing. The sensor detects and outputs a sensing signal. The control module receives the sensing signal and outputs a control signal. The airflow guiding structure is disposed adjacent to an air outlet and extends to the extension space.
