WebCopy Command. This example implements the field-oriented control (FOC) technique to control the torque and speed of a three-phase permanent magnet synchronous motor (PMSM). The FOC algorithm requires rotor position feedback, which is obtained by a quadrature encoder sensor. For details about FOC, see Field-Oriented Control (FOC). WebApr 28, 2024 · The expression for power developed by the synchronous motor in terms of α, θ, V, E b, and Z s are as follows. Let, V = Supply voltage. E b = Back emf per phase. α = Load angle. θ = Internal or Impedance angle = Tan -1 (X r per Z s ). I a = Armature current per phase = E r per Z s. Z s = R a + J X s = Synchronous impedance.
