PURPOSE:To obtain a device capable of decreasing numbers of high-pressure resistive parts and simplifying construction as well as making adjustment or parts interchanging easy by applying a voltage signal for a main motor to a magnetic amplifier through a differentiating circuit after insulating by a D.C. transformer. CONSTITUTION:Voltage for motors M1,M2 are applied to D.C. convertors DCPT1, DCPT2 through resistors R01, R02 respectively. Differentiating circuits R'1.C1, R'2.C2 are connected to the output sides of the D.C. convertors and the outputs thereof are applied to control coils NC1, NC2 for a magnetic amplifier MA. When idling is caused in any one of wheels W1, W2, the voltage of the motor M1, M2 are varied and the variations are transmitted to the control coils NC1, NC2, and thereby, the magnetic amplifier MA which operates a brake B is responsed. |
