But there are the following problems for DC excitation High-Speed Eddy Braking technology at present：During train braking, the vortex on rail
Substantial amounts of heat is produced, the temperature of rail is increased, therefore the parameter such as its electrical conductivity and magnetic conductivity will all change.Eddy-current brake
Power is relevant with the resistivity and magnetic reluctance of rail, therefore rail temperature rise certainly will impact to eddy-current brake power.Meanwhile temperature rise
The mechanical property of rail is changed, rail is softened, the life-span of rail can be reduced.In addition, High-Speed Eddy Braking needs are outer
Amplify field power supply, need to consume electric energy during braking, the danger of brake fade when power-off and electric energy deficiency be present, and low speed
When, brake force is small, is applicable train speed narrow range.
