The invention discloses a PCB coil and an angle measuring method for an
electromagnetic induction type angle sensor apparatus. The PCB coil and the angle measuring method for the
electromagnetic induction type angle sensor apparatus comprise a receiving coil for receiving a
signal sent by a rotor reflection coil, an excitation
magnetic field rotor reflection coil for receiving
stator transmitting coil, and the
stator reflection coil for sending an
excitation signal to the rotor reflection coil; the receiving coil and the
stator transmitting coil are connected and fixed to a stationary rotation shaft, the rotor reflection coil is arranged on a sensor rotor, the three coils are coaxially and fixedly arranged in parallel, the rotor reflection coil comprises an annular coil portion and a
copper portion, and the annular coil portion and the
copper portion are fan-shaped. The PCB coil and the angle measuring method for the
electromagnetic induction type angle sensor apparatus can implement non-
contact angle measurement, has the advantages of high accuracy, low cost, installation convenience, maintenance and management easiness and low environmental requirements, can accurately, stably and quickly complete tasks and solves many problems such as reliability, accuracy and cost of angle measurement methods.
