摘要

This paper shows the possibility and effectiveness of using an electric brake of motor railcar rolling stock with an asynchronous traction drive as an automatic brake. Since electric braking is unaffected by low temperatures and it can provide high efficiency protection from wheel slipping and skidding when integrated into a traction drive control system, as well as control braking torque with a high speed. Many motor axes and, hence, high power railcar rolling stock can provide less braking distance at electric braking than does pneumatic braking, which is especially important for emergency braking. However, an electric brake can be used as an automatic one only if it can be driven even in the case of loss of power from the catenary or diesel generator. The possibility in principle and the workability of using an electric brake as an automatic one are analyzed on the basis of mathematical simulations. The electromagnetic processes in an asynchronous traction drive under such conditions are considered, and the actuation time of an electric brake in the absence of supplied power is determined.
