摘要： A rotation sensor assembly includes a rotated component rotatably coupled with a base. The rotation sensor assembly includes a transmitter and a receiver. The transmitter is coupled with the base or the rotated component. The transmitter generates a magnetic field including a sinusoidally time-varying dipole near-field corresponding to an excitation signal having a first phase value. The receiver is coupled with the other of the rotated component or the base. The receiver detects the magnetic field and generates a reception signal based on the magnetic field with a second phase value corresponding to a rotation angle of the rotated component relative to the base. The receiver is mechanically isolated from the transmitter. A rotation angle module is coupled with the transmitter. The rotation angle module, for instance a phase detector, measures the rotation angle of the rotated component based on the phase difference in the first and second phase values.
