Abstract
Taught herein is a controller for a DC brushless motor comprising a control board () and a housing (); wherein the control board () is disposed in the housing (), and the housing () is made of metal materials with good thermal conductivity; a plurality of heat sinks () are disposed at the bottom of the housing (), thereby heat generated by the control board () will be dissipated fast, and the operating temperature and failure rates are reduced; an integrated power module chip () disposed at the bottom of the control board () transfers heat to the housing () via an insulating heat sink (), and in doing so prevents electric leakage; the purpose of a plurality of gaps () disposed at the top of the housing () is to provide ventilation, and to dissipate heat fast; all of these design characteristics make the invention simple in structure, and convenient for mass assembly.
