The electromechanical braking principle of mine hoist is described,and the detailed parameters and braking performance of the electromechanical brake are given.In addition,a large-load,high-response electromechanical brake test platform was designed and developed.The test results show that the braking error of the designed electromechanical brake is less than 9%,and the braking gap elimination time is less than 0.1 s.The motor current input is linearly related to the brake positive pressure output,with a slope of 4.11 and an intercept of 0.58,which meets the requirements of positive pressure of the mine hoist.The screw displacement output and brake pressure output are in a cubic relationship with a small zero error.
