Abstract (en)

[origin: WO2018170906A1] A brushless motor (22) includes a casing (34) which at least partially accommodates a stator and a rotor, an end cap (40) located adjacent to an end of the brushless motor; and a circuit board (32) which contains a controller for the brushless motor. The circuit board is located outside of a region defined by the end cap and the casing. As the circuit board is placed outside of the casing and the end cap, there is no need to configure a separate heat-sink for the circuit board, but the end cap to which the circuit board is mounted becomes a large heat-sink for the circuit board. This provides improved heat dissipation efficiency for both the circuit board and the stator /rotor of the motor.
