Abstract

The control and protection circuit, for the traction motor of a vehicle has the output of its current detector (5) coupled to an analog circuit (4) and to a 3-position regulator (2). An integrator (3) is connected to the output of the analogue circuit and feeds an analogue comparator (7) coupled to the analogue circuit output and to a voltage divider (9). The integrator is controlled by the speed monitor (6), by the analogue circuit and by an input circuit (1). The protection circuit (8) is connected to the outputs of the comparator and the analogue circuit.
