摘要： A rotary position sensor having a transmitter coil energized by a high frequency current source. A first receiver coil includes an even number N of loops wherein adjacent loops of the first receiver coil are oppositely wound. A second receiver coil also includes N loops where adjacent loops are oppositely wound. Furthermore, the second receiver coil is angularly offset from the first receiver coil by 180/N degrees. A noncircular coupler constructed of an electrically conductive material is rotatably mounted relative to the coils so that the coupler element overlies at least a portion of the first and second receiver coils. A circuit processes the output signals from the first and second receiver coils and generates an output signal representative of the rotational position of the coupler.

摘要： A linear position sensor having a transmitter coil which generates electromagnetic radiation when excited by a source of electrical energy and wound in a first direction. A receiver coil is contained within the transmitter coil and the receiver coil includes both a first loop wound in a first direction and a second loop wound in the opposite direction. A coupler element linearly moves along a first direction relative to the transmitter coil which varies the inductive coupling between the transmitter coil and the receiver coil as a function of the linear position of the coupler element to thereby vary the electrical output signal from the receiver coil when excited by the transmitter coil. The first and second loops of the receiver coil are linearly aligned with each other along the first direction.

摘要： A rotary position sensor having a transmitter coil excited by a high frequency signal source. A first and second receiver coil, each having at least two oppositely wound loops, are rotatably positioned electrically 90 degrees relative to each other. The receiver coils are positioned so as to be inductively coupled with the transmitter coil while a coupler constructed of an electrically conductive material is rotatably positioned over and inductively coupled with the first and second receiver coils. The outputs from the first and second receiver coils are coupled through a high pass filter and a low pass filter, respectively, thus creating a 90° phase shift in the resultant signals. These signals are summed together and coupled as an input signal to a PWM circuit together with a signal from the transmitter coil.

摘要： A sensor circuit for use with a shaft assembly rotatably mounted in a housing and having an input shaft, an output shaft and a torsion bar which connects the input and output shafts together. A CR coil mounted to the housing around the shaft assembly is energized and generates an electromagnetic field. An RX coil is mounted to and rotates with the shaft assembly and has an output connected to a power circuit to generate electrical energy when excited by the electromagnetic field from the first coil. The power circuit powers an angle sensor which transmits a signal back to the first coil representative of the angle between the input and output shafts.
