Patent number: 11387751Abstract: A device for speed-dependent braking torque control for electrical machines excited by permanent magnets includes a switching device deliberately short-circuits the electrical machine. The switching device is controlled as a function of an induced voltage generated by the electrical machine. If the induced voltage falls below a defined value, the switching device reverses the short-circuited state of the electrical machine to cause the braking torque to reduce to zero and the speed to increase again. The speed can thus be controlled within a range by alternately opening and closing the switching device.Type: GrantFiled: June 24, 2019Date of Patent: July 12, 2022Assignee: KNORR-BREMSE Systeme fuer Nutzfahrzeuge GmbHInventor: Sebastian Schaller
