The measured VSI dc-link current is fed to a space-vector-based lookup table, which reconstructs the motor line currents. Three Luenberger-style observers are used to filter out the reconstructed ...

A FULL discussion is given in this book of the practical theory of the induction motor and of several of the main types of alternating current motors. The author also gives a historical account of ...

Direct current, or DC, is a type of electrical current that only flows in one direction. In contrast to alternating current, or AC, which, depending on the supply's frequency, switches direction ...

Abstract: For the calculation of torque in brushless (BL) alternating current motors a local method is proposed, based on the Maxwell stress theory and the filtered contributions due to the harmonics ...
