Cogging torque, permanent-magnet, finite-element method.
Cogging torque is perhaps the most annoying parasitic
element in a permanent magnet machine design because it
represents an undesirable output. As a result, techniques
to reduce cogging torque play a prominent role in
machine design. In this paper, two different methods that
can be used to reduce cogging torque are discussed, both
theoretically (using finite element method FEM), and
empirically (measuring it in several prototypes).
