The block is used in BDCM simulation and allows you to determine the electrical angle of the rotor with an accuracy of 60°. The rotor position sensor has three channels. Each channel generates a pulse corresponding to half of the period for one period of the electric angle, while the pulses of the channels are shifted by a third of the period (120 electric degrees).
The trapezoidal shape of phase EMF depending on the electric angle of the rotor is shown in the figure (Figure 1):
Рисунок 1. Trapezoidal shape of phase EMF
The matching of the signals in the channels to the electric angle is explained by the following table (Figure 2):
