A Coupled Vector-scalar Potential Method For Permanent Magnet Modeling in Large-scale 3d-Fe Magnetic Field Computations

Alhamadi, M.A.; Demerdash, N.A. ( IEEE , 1993 , Conference Paper)

This paper introduces a magnetic scalar potential (MSP) formulation of permanent magnet (PM) modeling. This formulation is suited for use in coupled (combined) vector-scalar magnetic potential (CMVP-MSP) 3D-FE algorithms ...

Speed control of induction motor without rotational transducers

Ben-Brahim, Lazhar; Tadakuma, Susumu; Akdag, Alper ( IEEE , 1999 , Article)

This paper describes a newly developed speed sensorless drive based on neural networks. A backpropagation neural network is used to provide real-time adaptive identification of the motor speed. The estimation objective is ...
