Investigation on the Output Signal of Rotational Speed Sensor for Different Flux Surfaces between Gear Wheel and Sensor

Abstract:

Rotational Speed Sensors are typically used to measure rotational speed in automotive application such as ABS (Anti-lock Braking System), ASR (Anti Slip Regulation) or Gear Box. In terms of application area, rotational speed sensors transmit very important signal from gear wheel to ECU (Electronic Control Units). The output signal of rotational speed sensor (RSS) may not provide exact solution in high speed situation because RSS is a kind of inductive sensor which has discharge and charge time. Thus, response time of RSS may lead a problem for exact speed measurement while the output signal is settling. In this study to evaluate different flux surfaces, both low speed @0.8RPM and high speed @3992 RPM, 6 experiments were performed for normal, convex and concave teeth setups. It has been seen that the output signal form of convex teeth setup is more appropriate than normal teeth setup and concave teeth setup for sinus signal.
