Bob Pease had a special love for voltage-to-frequency converter circuitry. I did a vamp on his writing in an article of my own. If you want to measure a voltage in a remote location, it might be ...
Abstract: High-frequency signal injection method is a common control strategy for interior permanent magnet synchronous motor (IPMSM) drives at zero and low speeds. A reasonable demodulation method is ...
Abstract: This paper proposes a sensorless speed control method for brushed dc motors that extends the usable speed estimation range by combining current-ripple analysis with high-frequency signal ...
