Eddy current machine brake control device

摘要

According to the invention, the eddy current machine load control device comprises a comparator having a first input for the supply of voltage of a predetermined magnitude and a second input connected to an output of an electrical machine load transducer which is an actual value transducer intended to convert mechanical stresses to electric signals. The device further includes a threshold element, a diode and a proportional-integral-derivative voltage regulator having its input connected to an output of the comparator, whereas an output of said PID voltage regulator is coupled via the diode to a controlled input of a controlled power source of the electrical machine.
