Summary:A method and device for the electrodynamic braking of a universal motor. The method comprises continuously ascertaining a rotational speed of the universal motor, temporarily, periodically short-circuiting an armature of the universal motor with a semiconductor switch to brake the universal motor, and setting firing angles of the semiconductor switch according to an indexed mapping of firing angles to target rotational speeds of the universal motor. Each of the set firing angles is adapted to an ascertained rotational speed value.
