Abstract
When the tires interact with the road in contact, self-oscillations occur. The excitation of self-oscillating negatively affects the operation of the mechanical parts of the individual electric drive, leading to their breakdowns due to an increase in the dynamic components of the loads as a result of fluctuations in the values of rotational speeds and torques, including with a change in the sign of the moment. This paper presents the results of an experimental study of the occurrence of selfoscillations in the zone of interaction of the tire with the support base under operating conditions. The modes of occurrence of self-oscillations during partial and full sliding in the case of anti-lock and anti-slip systems are analyzed. Self-oscillations of the torque and wheel speed cause similar processes on the shaft of the electric motor, which is accompanied by fluctuations in the stator current. Keywords self-oscillation, wheel, sliding, electric motor, individual drive, experimental studies, stator current, operation
