Description:
An accurate 3-D nonlinear transient finite-element model of an eddy current brake (ECB) has been developed, with consideration of the skin effect, eddy current distribution, nonlinear magnetization-saturation and rotation. Based on the analysis of the eddy current path (ECP) and penetration depth, the influence of principal parameters related to the braking process is analyzed. After analysis and comparison with the common round pole, a novel pole with sector shape has been developed, which brings about a significant increase of braking torque. An eight-pole ECB device with a peak torque of 4220 N · m under an excitation current of 88 A has been designed and tested for use in high-speed trains. The test results agree well with simulations.
