FOC BLDC Dashboard

Field-oriented control of a PMSM: current loops, SVPWM limits and operating envelope.

FOC BLDC Interactive Dashboard

Simulates dq current-loop dynamics with PI control and constant electrical speed. Models based on standard PMSM/BLDC FOC equations.

Currents i_d, i_q

Torque & Voltages

Voltage vector is saturated to |v| ≤ Vdc/√3 for SVPWM linear region.

Equations Used

dq dynamics: v_d = R_s i_d + L_d di_d/dt − ω_e L_q i_q; v_q = R_s i_q + L_q di_q/dt + ω_e (L_d i_d + λ_f)
Torque: T_e = 1.5·p·(λ_f i_q + (L_d − L_q) i_d i_q); for SPMSM L_d≈L_q ⇒ T_e≈1.5·p·λ_f·i_q
Electrical speed: ω_e = p·ω_m; with ω_m = 2π·rpm/60
SVPWM voltage limit (linear): |v| ≤ V_dc/√3
Clarke/Park transforms underpin dq modeling (not explicitly simulated here).
