How hall sensors work in a motor

Hall sensors are linear transducers. Such sensors require a linear circuit for processing the sensor output signal. This circuit provides the drive voltage for the sensor and is used to amplify the output signal. In some cases, the linear circuit may cancel the offset voltage of Hall sensors. Moreover, AC modulation of the driving current may also reduce the influence of this offset voltage. WebA Hall effect sensor varies its output voltage based on the strength of the applied magnetic field. A PMSM consists of three Hall sensors located electrically 120 degrees apart. A PMSM with this setup can provide six valid combinations of binary states (for example, 001,010,011,100,101, and 110).
