📖 What Does It Do?

Motor permanent magnet flux linkage. Physical motor constant for FOC control.

🎯 Recommended Values

Default value: 90

Valid range: 0 to 1000

Tuning Strategy

Start with the default value and adjust in small increments. Monitor vehicle behavior after each change before making further adjustments.

💡 Tuning Tips

Used in MTPA algorithm to calculate optimal Id/Iq split. Higher = stronger magnets = more torque but less top speed.

TYPICAL VALUES:

  • Default: 90 (generic)
  • Nissan Leaf EM57: 73 mWb (measured)
  • Toyota Prius MG2: ~50-60

    • This is a PHYSICAL CONSTANT of your motor — not a free tuning parameter. Use known values or measure back-EMF.

    🔗 Related Parameters

    Other parameters in the Motor Control category that work together with fluxlinkage:

    fmax

    Hz

    Maximum motor frequency. RPM = fmax × 60 / polepairs.

    boost

    dig

    Voltage at 0 RPM — controls starting torque. Higher = stronger launch.

    fweak

    Hz

    Field weakening start frequency. Above this, motor enters constant-power region.

    numimp

    ppr

    Speed sensor pulses per revolution.

    polepairs

    Motor pole pairs. CRITICAL — set this correctly for your motor.

    fslipmax

    Hz

    Maximum slip frequency (induction motors). Sets full-throttle torque.

    snsm

    enum

    Motor temperature sensor type. Must match your motor's actual sensor.

    fslipmin

    Hz

    Minimum slip frequency (induction motors). Sets creep torque.

    encmode

    enum

    Encoder/position sensor type. This is your motor's 'eyes' — it tells the inverter where the rotor is.

    dirchrpm

    rpm

    RPM below which direction change is allowed.
