Rotating shaft angle position sensing device and sensing system
ActiveCN104180752APrevent axial displacementAvoid vibrationUsing electrical meansElectric signalMagnet device
The invention provides a sensor for sensing an angle position of a rotating shaft and a sensing system, wherein a magnet conductive block is fixedly arranged on the rotating shaft and can rotate along with rotation of the rotating shaft. The sensor comprises a magnet device and a Hall effect sensing component. The Hall effect sensing component is used for sensing the angle position of the rotating shaft. When the magnet conductive block rotates along with the rotating shaft, a magnetic field which is generated by the magnet device is changed. The Hall effect sensing component generates an electric signal along with magnetic field change. The electric signal indicates the angle position of the rotating shaft. Because built-in U-shaped back magnet technology is adopted for the sensor of the invention, sensing precision of the sensor is greatly improved. Therefore a precision requirement for measuring the angle position of the rotating shaft can be satisfied through using a single IC chip which is provided with one Hall effect sensing component.
