A microscopic investigation of force generation in a permanent magnetic synchronous machine
Keywords and Phrases
Maxwell Stress Tensor
"Traditional analysis of permanent magnet synchronous machines has focused upon establishing a relationship between the q- and d-axis stator current (or voltage) and the tangential component of electromagnetic force (torque), which is created to yield rotor rotation. Although useful, traditional analysis fails to consider the vector component-nature of force generation, i.e. that both radial and tangential components of force are created. The research described herein documents the effort to characterize the behavior of both radial and tangential components of force. Specifically, using a combination of analytical and numerical techniques, the influence of q- and d-axis stator current on both the radial and tangential component of airgap flux density is first evaluated. A Maxwell Stress Tensor approach is then used to evaluate the radial and tangential component of force...one can conclude that the magnetic fields established create a significant component of force in a direction that does not produce rotor rotation"--Abstract, leaf iii.
