WebHall ef fect sensors are economical and because of the permanent magnets inside a BLDC motor are easy to install inside the motor . The motor in this application note comes with the Hall ef fect sensors pre-installed. Because of the six-step control scheme, there is no need for a high resolution output from the sensor . The BLDC Motor Control ... 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.
