Abstract

Compared to eddy current braking pattern with single magnetic source exciting, hybrid excitation rail eddy current brakes has many advantages, such as controllable, energy saving and various-operating-modes. Aiming at large braking power consumption of high-speed train, a hybrid excitation rail eddy current brake system, which is based on the principle of electromagnetic field, is proposed to fulfill the needs of safety and reliability. Then the working processes of mechanical lifting system and electromagnetic system are demonstrated. With electromagnetic system analyzed using FEM, the factors such as speed, air gap, exciting current, which have influences on braking force and attractive force, are discussed.
