Abstract
The invention concerns an inductive transmitter comprising two coils (1, 2), each with one core (3, 4). The two cores (3, 4) are capable of being moved relative to each other. Two systems are integrated in the transmitter that make it possible to simultaneously transmit data and/or energy, as well as the position of the two cores (3, 4) relative to each other. Finally, the transmission of data and/or energy takes place by means of induction, and the determination of the position of the two cores (3, 4) relative to each other takes place via a measurement of the magnetic field that exists between the two coils (1, 2).
Claims14
Inductive transmitter comprising two coils (1, 2), each with one core (3, 4), having the following features:
- the two cores (3, 4) are capable of being moved relative to each other,
- two systems are integrated in the transmitter that make it possible to simultaneously transmit data and/or energy, as well as the position of the two cores (3, 4) relative to each other, and
- the transmission of data and/or energy takes place by means of induction, and the determination of the position of the two cores (3, 4) relative to each other takes place via a measurement of the magnetic field that exists between the two coils (1, 2).
Inductive transmitter according to one of the preceding claims, whereby the contour (5) is designed as an incline.
Inductive transmitter according to one of the preceding claims, whereby a magnetic field-sensitive sensor (6) is provided.
Inductive transmitter according to one of the preceding claims, whereby the sensor (6) and the contour (5) are situated opposite to each other.
Inductive transmitter according to one of the preceding claims, whereby the sensor (6) is located in the air gap (7) between the two cores (3, 4).
Inductive transmitter according to one of the preceding claims, whereby the sensor (6) is located on one core (3, 4), and the contour (5) is located on the other core (3, 4).
Inductive transmitter according to one of the preceding claims, whereby the sensor (6) and the contour (5) are located on the same core (3, 4).
Inductive transmitter according to one of the preceding claims, whereby the motion of the two cores (3, 4) relative to each other is a rotary motion.
Inductive transmitter according to one of the preceding claims, whereby the motion of the two cores (3, 4) relative to each other is a linear motion.
Inductive transmitter according to one of the preceding claims, whereby the cross-section of the cores (3, 4) is designed in the shape of an “L”, and the contour (5) is formed on an arm of the “L”.
Inductive transmitter according to one of the preceding claims, whereby the cross-section of the cores (3, 4) is designed in the shape of a “U”, and the contour (5) is formed on at least one exposed arm of the “U”.
