Hand-held power tool e.g. drilling hammer, has power electronics unit with cooling unit partially arranged within main cooling air flow during operating condition, where cooling unit is arranged between pole shoe and motor case

摘要

The power tool has a fan unit (14) for providing main cooling air flow between an armature of an electromotor (10) and a motor case (12). A power electronics unit (20) has a cooling unit partially arranged within the main cooling air flow during an operating condition, where the cooling unit is arranged between a pole shoe and the motor case. The fan unit has a radial fan (16) coupled to the electromotor, and the power electronics unit is arranged on the motor case. A copper sheet is provided in the cooling unit.
