摘要： In order to protect a brushless motor, heat generated at a switching device, in response to an abnormality, activates a protection device. The protection device includes a connecting line communicating between a source supply line and the switching device. The protection device is provided near the switching device such that it can sense heat at the switching device with a high degree of sensitivity. Thus, when excessive heat is generated at the switching device, the protection device reaches a specific temperature, whereby the source supply line becomes cut off from the switching device, thereby immediately stopping the operation of the brushless motor.

摘要： Provided is a driving motor that will meet the requests of making the length of a rotating axis of the driving motor to be shorter in the axial direction, and which will also have waterproof, vibration resistance, and soundproof characteristics. In this driving motor (3); a motor interior-space (35) is formed by a housing (21) that has a first and second opening and which is formed to be cylinder shaped, and a flange (22) that blocks the second opening of this housing (21); and a stator assembly (18), a rotor assembly (20), a lower-side end section of the rotating axis (12) that has been placed lower than the flange (22) up until now, and a control circuit-board (19) are all made to be contained in this motor interior-space (35). Furthermore, a ring-shaped elastic member (45) is made to interpose between the upper-side end section of the rotating axis (12) and the first opening of the housing (21); and the lower-side end section of the rotating axis (12), the stator assembly (18), and the rotor assembly (20) are made to be fixed to the flange (22) through a mounting elastic member (59).

摘要： A brushless motor which includes an arrangement to prevent dielectric breakdown of electronic parts mounted on a control board. The breakdown is caused by a heat sink which becomes electrostatically charged. The potential at the heat sink, which contacts switching devices (for instance, FETS) of the brushless motor, is equalized with the potential at one side of a source line for a drive circuit formed on the control board that includes the switching device. As a result, when the heat sink becomes electrostatically charged, the charge at the heat sink can be discharged to the source line, thereby eliminating the above problem.
