InstaSPIN-FOC Flux

Gets the flux value in Volts per Hertz (V/Hz).

The estimator continuously calculates the flux linkage between the rotor and stator, which is the portion of the flux that produces torque. This function returns the flux linkage, ignoring the number of turns, between the rotor and stator coils, in Volts per Hertz, or V/Hz. This functions returns a precise value only after the motor has been identified, which can be checked by the following code example:

 if(EST_isMotorIdentified(handle))
   {
     // once the motor has been identified, get the flux
     float32_t Flux_VpHz = EST_getFlux_VpHz(handle);
   }

Parameters:

[in]

handle

The estimator (EST) handle

Returns:

The flux value, V/Hz, in floating point
