Estimation of the Realization of Traction Force on the Adhesion of AC Electric Locomotives with an Asynchronous and Collector Drives
The article is devoted to the analysis of traction and power tests materials of 2ACS and 2AC7, new alternating current electric locomotives with an asynchronous drive, which claim that such electric locomotives have advantages over 3ACS, a domestic three-section electric locomotive with a collector drive. Merits and demerits of hard traction characteristics of the asynchronous drive as compared to soft traction characteristics of the collector drive on realization of traction force at the limit of adhesion and fast adhesion recovery after slipping emergence are assessed. The conclusion is drawn about impossibility of sustained locomotive operation at the limit of adhesion although locomotive operating mode regards slipping as operating traction mode. The impossibility is proved by statistics of malfunctions of traction motors.
