// 1. Measure electrical frequency
F_elec  = RPM × pole_pairs ÷ 60

// 2. Find Fibonacci multiplier — zero residual guaranteed
FIB[]   = {1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377...}
FOR n = 0 TO 16:
  F_sw = F_elec × FIB[n]
  IF 8000 ≤ F_sw ≤ 40000: BREAK    // residual = 0 by definition

// 3. Amplitude tracks load — iron loss ∝ V²
V_opt   = V_bus × √(load_kW ÷ peak_kW)

Coverage proof: band ratio 40000÷8000 = 5.0 > φ² = 2.618 → always one Fib in range. No gaps.
