US 23539205 A description as shown in fig1 a the disclosed low force level detection system and method is embodied in an electromechanical brake system generally designated 10 brake system 10 may include a housing 12 a motor 14 e g an electric motor a processor 15 a sensor 17 an actuator 16 two brake pads 18 20 a rotor 22 the motor 14 may include a ball screw assembly and a gear train not shown that may translate the rotational force of the motor 14 into distal advancement of the actuator 16 thereby urging the actuator 16 linearly into engagement with the brake pads 18 20 as the actuator 16 engages the brake pads 18 20 the brake pads 18 20 clamp the rotor 22 and supply a braking force to the rotor 22 as shown in fig1 b as shown in fig2 as the actuator 16 moves from its initial position p i see also fig1 a to the clamping position p c see also fig1 b the motor 14 may be generally in a no load state i e there is no clamping force exerted by the motor 14 in the no load state the no load motor speed u03c9 nl motor speed is not shown in fig2 and the no load motor current i nl may remain relatively constant when a constant voltage is applied across the motor 14 however as the actuator 16 contacts the brake pads 18 20 and.
