Abstract

PURPOSE: To operate a control at a constant braking force in accordance with a braking force command by utilizing an output of speed generator, when operating a dynamic braking by separate-excitation controlling a field current.
CONSTITUTION: For a main motor rotational speed N detected by a speed generator 5 and for a braking force command value Bp given by a braking force command device 7, a braking current pattern generator 6 will output IP, LP=K1(Bp×N)1/2 (where K1 is a constant). A braking current IM of the main motor 1, with said braking current pattern IP detected by a current detector 8, is compared and amplified in a comparator 9, and a field winding 2 will be automatically adjusted so as to obtain a relation of LM=IP. In this way, a braking force B will be obtained proportional to the braking command value Bp
