As an antilock system for a permanently excited electric motor drive, especially for a steering booster servo drive of a motor vehicle, in the event of a winding short-circuit, an interruption of at least one winding phase (MP1 or MP2 or MP3) of the winding affected by the short circuit is provided, by a separating means (T) triggered by an explosion directly or indirectly by the winding short-circuit. The antilock system advantageously has a separate neutral point connection part (MP) which is especially embodied as a sheet metal moulded part, is to be connected to the winding ends of the electric motor, and contains the winding phases (MP1; MP2; MP3) and the neutral point connection thereof as a single component. The antilock system is purposefully arranged on a front winding head of the electric motor and connected to the winding thereof.
