G-2372 C-4166 BI-MODAL DC MOTOR CONTROL FOR A MOTOR DRIVEN ANTI-LOCK BRAKE SYSTEM Abstract of the Disclosure Differential performance characteristics are achieved in a motor-driven anti-lock braking system with a DC motor having a first brush which is employed for both forward and reverse motor rotation, a second brush which is employed in connection with the first brush when forward motor rotation is desired, and a third brush which is employed in connection with the first brush when reverse motor rotation is desired. The second and third brushes are displaced along the circumference of the motor commutator such that the first and second brushes encompass more turns of the rotor winding than the first and third brushes. As a result, more of the winding turns are active in the forward direction, and the motor torque is maximized for developing the required brake pressure. On the other hand, fewer of the winding turns are active in the reverse direction, and the motor speed is maximized to relatively quickly retract the armature within the valve bore to relieve the brake pressure.
