| Abstract |
This paper describes various methods aimed at estimating the rotor position for an AC 3-phase induction motor without a shaft sensor using specially designed asymmetric rotors. A High Frequency (HF) signal needs to be injected so as to detect the rotor position. As is common knowledge, saturation causes estimation problems when using HF injection, this effect and ways to overcome this problem are discussed. The methods considered assume a saturated induction motor having an engineered cage saliency spanning one pole pitch. The performance of these methods is investigated at all loads at low speed. |
