New brake-force sensors support electromechanical braking in EVs
Sensata Technologies has announced that its brake-force sensors are being used in electromechanical braking (EMB) systems in production electric vehicles (EVs). The sensors measure clamping force directly within the brake caliper, providing real-time feedback for closed-loop braking control at each wheel. Unlike conventional hydraulic braking systems, which use fluid pressure to actuate the brakes, EMB…

The cell incorporates dry-printed anode and cathode layers with a carbon fiber veil and a conductive…
What causes bearing currents in EV motors and how engineers prevent them
An electric vehicle (EV) traction inverter can drive unwanted current through the motor bearings. Its switching creates voltage on the motor shaft, even without a direct electrical connection between the windings and rotor. If the voltage across a bearing exceeds the insulating capability of its lubricant film, a brief electrical discharge pits the bearing surfaces.…
