摘要
Device of dynamic measurement of the torque ci of a self-synchronous motor, a polyphase 1, 2, 3). / p & & p & it comprises a sensor 4 of the electrical angle a between one of the phases i1 and the axis perpendicular to the magnetic moment apmm, the circuits 38 to 40 of the calculation of the cosine of the angles a, a - 120degre (s), a + 120degre (s) between each phase and the apmm, the current sensors 31, 32, 33 on each phase, and means 47 to 49, 56 to 63 for calculating the torque c by applying the formula: c = k [i1.cos a + i2.cos (a - 120degre (s)) + i3.cos (is + 120degre (s))] ≦ / p
