Failures of automotive starters make it impossible to reliably start internal combustion engines, which, under adverse circumstances, may cause a risk of road traffic accidents. A significant part of starter failures is associated with electrical faults in electric motors. The occurrence and development of failures causes a change in the torque produced by the starter. A mathematical model of the starter’s performance dependant from the magnitude of the electrical resistance of its windings was developed. Physical modeling of failures was carried out using an adjustable active resistance connected in series and parallel to the armature winding. Critical values of electrical resistance correspond to an open and short circuit of the armature winding of the starter electric motor, and, consequently, to starter failure. The results obtained are instrumental to the development of a diagnostics method for automotive starters without removing them from the motor.
