WebThe example determines the best possible initial estimation for the rotor position using open-loop PHF injection, which it uses further for running closed-loop PHF. It executes closed-loop PHF by injecting a high frequency signal into the estimated rotor position to determine the actual rotor position, without spinning the motor. WebFeb 25, 2015 · Okay, so I'd like to be able to inject a really simple signal on top of the 60Hz AC Mains. It doesn't have to contain any data per se, just a simple signal to trigger a receiver on the same subcircuit.. I'm imagining the simplest way to do this is to create a high frequency pulse on the line that the receiver could detect with a simple bandpass filter.
