This component is the same as the Brushless DC machine, except that it has additional Hall Sensor and back-EMF-voltage outputs available.
The following depicts the hall sensor signals with respect to the electrical angle and the phase-to-phase back-EMF voltages.
θe = electrical angle
θm = mechanical angle
P = number of rotor pole pairs
|Ha||Hall sensor A signal.|
|Hb||Hall sensor B signal.|
|Hc||Hall sensor C signal.|
|Ea, Eb, Ec||Measurement pins for the back-EMF voltages. These are values of voltage sources Va, Vb, and Vc in the figure above.|
