| Abstract |
In this paper, the test voltage injection coupled
with tracking of magnetic saliencies created by saturation
and rotor slotting was used for shaft sensorless speed
control of induction motor drives at zero and low speed.
Method does not require additional wire connections and is
usable for star or delta machine connection. The paper is
proposing low memory method of elimination saturation
effect from position signals, which are obtained from
sensors of line current derivations. Experimental results are
presented shoving tracking of rotor speed and position,
signal processing with proposed method and shaft sensorless
speed control as well. |
