Latest Patents
Haffray holds a patent for a position detection device of active magnetic bearings. This device is designed to maintain the position of a rotating shaft and includes two sensing inductance coils. The system features a programmable digital component that generates a 25 KHz square waveform signal. A current amplifier receives this signal and injects identical control currents into the two sensing inductance coils. Additionally, a differential amplifier amplifies the voltage difference between the resulting voltages in the coils. Depending on the displacement of the rotating shaft, an analog to digital (A/D) converter delivers a position value derived from the voltage difference. Haffray's innovative approach has led to the development of a device that significantly improves the functionality of AMBs.
