What is a PAS( Pedal Assist Sensor)? What functions does it have? What is the difference for different number magnetic? The PAS is a sensor installed on the electric bike central axle. Its function is to convert the pedaling action into a pulse signal that can be recognized by the controller. The sensor is divided into two parts, the disk, and the sensor. The disk rotates with the shaft when you step on it. The sensor is fixed. There is magnetics on the disk, each magnetic will trigger the kiln element in the sensor to act once when passing through the sensor. The more magnetics, the faster of the triggered signal frequency. For example, if the five magnets rotate one cycle, there are five pulse signals, eight magnets-eight pulse signals. The PAS is to give a signal, no control function. It needs the controller to identify these signals, then output control according to the frequency of the pulse. So the effect of the PAS: good or bad, fast or slow, is a matter of the controller’s processing effect. It is not about the quantity of the PAS. The more magnetics PAS has, the smoother the output signal, and the pedaling speed is more accurate. So more magnetics is the better when the controller can recognize the signals. What is the difference between single Hall and double Hall? A single Hall Pedal Assist Sensor has a built-in Hall in the head of the sensor when inductive a magnetic signal it will emit a signal. Such a sensor is greatly affected by the installation environment and has poor stability. Moreover, both forward and reverse will have an output signal, which requires the controller to recognize the forward or reverse. Dual Hall has two built-in Hall and signals conversion circuits to improve the stability of the output signal. In addition, it can also identify the polarity of the magnetic and can control the forward rotation with signal output and the reverse without signal output. Perform signal recognition control. The dual-Hall performance is better when the controller is compatible. […]
