Electronic slip regulation controller for rail locomotive - allows phase synchronised or independent regulation of motor currents for both half axes

摘要

The electronic slip regulation controller uses a phase regulator controlling the motor currents for the 3-phase drive motors for the 2 half axes of a lost wheel set. The 2 half axes can be coupled together, driven independently of one another, or the slip between the 2 half axes can be regulated. When the half axes are coupled the motor currents are phase synchronised, but during independent operation the motor currents are controlled independently. During the slip regulation the motor currents are controlled at different frequencies. Pref. during slip regulations the motor currents for the drive motors on the inside of the curve has an extended period and the motor currents for the drive motors on the outside of the curve has a shortened period. ADVANTAGE - Effective slip regulation on sharp curves.
