Abstract
Official abstract text for this publication.
A brushless DC motor structure including a motor body, a controller, and a fan radiator. The fan radiator is mounted between the motor body and the controller to disperse heat from the motor body and the controller. The brushless DC motor structure increases air flow on the surface of the motor body and the controller by the fan radiator and speeds up heat dispersion, and meanwhile effectively controls the operating temperature of the motor body and the controller. Thus, the brushless DC motor structure has an excellent heat dispersion capability, and the failure rate thereof has been largely reduced.
