Technical Examples

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