摘要: A position transducer for a rotary member such as the rotor of motor has rotating encoder disc and flat, disc-shaped elements interacting with to produce dependent signals. The at least one active element metal surfaces configured so that signals from several portions or sectors system are not transferred another portion sector, thus permitting be split into detectors can operate independently each other without having detector affecting detectors. cover individual circular concentric rings e.g. based on sensing capacitive coupling between transmitter sensor electrodes located opposite sides disc. components assembled substantial air gaps them made materials easily destroyed by corrosion contaminants like dust particles, water, oil lubricant grease. also permits detecting multiturn rotation additional mechanical components.
