发明名称 Control device for an electric motor
摘要 The invention relates to a drive device (1) for an electric motor, in particular for a brushless DC motor in an electrical tool which is powered by a rechargeable battery. The drive device (1) has at least one power semiconductor (3), in particular for controllable application of an electrical voltage to the electric motor, a control circuit (4) for controlling the power semiconductor (3), and a mounting plate (2) which, for example, is in the form of a printed circuit board. At least one portion of the control circuit (4), in particular electrical and/or electronic components (5) as well as the conductor tracks (6) (which connect the electrical and/or electronic components (5)) of the control circuit (4), is arranged on the mounting plate (2). The power semiconductor (3) is arranged on the mounting plate (2) and/or on a mount element (7) which is mounted on the mounting plate (2).
