Abstract: The permanent magnetic direct drive electromagnetic brake has problems of big braking force, large volume and serious heating,so the paper solves the electromagnetic force in a simple way through the method of field-circuit combination, and uses the Ansys finite element software to make field analysis of electromagnetic brakes. Then, the paper analyzes the influence of parameters such as size, air gap,winding turns, high voltage suction time and low voltage holding voltage on the performance of electromagnetic brake, and designs a 220 kN electromagnetic brake. Finally, the prototype test verifies the correctness of calculation and analysis.
Key words: electromagnetic brake; permanent magnet direct drive; electromagnetic suction force
