On the multiturn side, the multiturn counting is enabled utilizing energy harvesting technology. When the shaft is rotating, the magnet mounted on the shaft moves in tandem. The energy-harvesting coil module cuts the moving magnet field, and generates energy as a result. The beauty of the energyharvesting effect is that the same amount of energy is generated independently of the rotation speed. The generated energy is suffi cient to power up the revolution tracking circuitry. Therefore, no miscounts occur even in the absence of external power supply. It can replace traditional gear technology due to absence of wear (no contact technology).
