Summary:A method and device for electrodynamic braking of a universal motor. The method comprises the steps of continuously ascertaining a rotational speed of the universal motor, temporarily, periodically short-circuiting an armature of the universal motor with a semiconductor switch, and regulating firing angles of the semiconductor switch with a regulating device. The regulating device regulates firing angles of the semiconductor switch such that the rotational speed of the universal motor is adapted with minimal deviation to a rotational speed of a target rotational speed profile.
