An electric power device may include a casing, a motor disposed within the casing, a control unit, and an air channel. The motor may be configured to operate a working implement of the device and may include a motor housing having at least one outlet through which air cooling the motor exits the motor housing. The air channel may be configured to enclose the at least one outlet of the motor housing. The air channel may provide a passage for the air drawn from outside the casing and through the motor housing out of the casing via an exhaust outlet disposed in the casing at an end of the air channel. |
