摘要
Abstract
Most tractors used two motors to control, and led to high energy consumption, large heat release and complex control.Due to these problems, an electropermanent magnet sucker was designed to provide enough normal forces between wheels and the pipe walls.So, the tractor might be drived by only one motor.The finite element method was used to simulate the electropermanent magnet suckers, which analyzed the impacts of various size parameters on the magnetization and demagnetization performances.Based on the simulation results, agroup of reasonable size parameters was selected.The errors between the actual values and the simulated values are less than 15％by the experiments of the electropermanent magnet sucker, and the well tractor with electropermanent magnet sucker may drag over 3 000 N.关键词
