PURPOSE: A switching element integrated brushless motor is provided to prevent power waste due to heat loss by removing a power source cable and a three-phase connector between the controller and a motor main body. CONSTITUTION: A brushless motor(100) includes a controller(200). A switching element(110) is installed in the brushless motor in order to control motor driving by applying currents. The switching element directly receives a power source from the outside not through the controller. The switching element is controlled by the controller through data communications. The brushless motor includes a heat sink(120) to cool the switching element by air. The switching element comprises at least one of a transistor, a FET(field-effect transistor), a junction FET, an MOS(metaloxide semiconductor) FET, and an IGBT(insulated gate bipolar transistor). |
