摘要
An envelope of a voltage may be extracted using an operator to calculate a position and speed of a rotor. A position and speed sensing method may include supplying voltage to a stator, coupling the voltage into a rotor, extracting an envelope of the voltage using an operator, and calculating a rotor angular position based on the extracted envelope. A position and speed sensing apparatus may include a stator, a rotor and a controller to extract an envelope of a voltage coupled through the rotor into the stator using an operator and to calculate a rotor angular position based on the extracted envelope.
