Device making possible in an interlock system, by positive clutch drive of two toothings, for a motor rotor for the purpose of reducing the consumption of current at the intake. The invention relates to a device for limiting the travel of the moving element of one of the toothings of a positive clutch drive interlock system installed on a motor. It consists of a screw 6 which locally keeps the moving part 3 close to the magnetic circuit of the exciter coil 1. In this way the releasing of the interlock requires less current in the coil 1. This device applies more particularly to systems for braking by positive clutch drive by means of motor-mounted toothings. <IMAGE>
