WebThe FOC algorithm requires rotor position feedback, which is obtained by a Hall sensor. For details about FOC, see Field-Oriented Control (FOC). This example uses the Hall sensor to measure the rotor position. A Hall effect sensor varies its output voltage based on the strength of the applied magnetic field. WebThe linear eccentricity (focal distance) is c = \sqrt {a^ {2} - b^ {2}} = \sqrt {5} c = a2 − b2 = 5. The eccentricity is e = \frac {c} {a} = \frac {\sqrt {5}} {3} e = ac = 35. The first focus is \left (h - c, k\right) = \left (- \sqrt {5}, 0\right) (h − c,k) = (− 5,0).

By its basic definition, FOC simply means controlling the orientation of a motor’s field(s) to achieve a desired result. From that definition, all motors do field-oriented control in one form or another.
