- 11.1: Introduction
- Virtually all electric machines, and all practical electric machines employ some form of rotating or alternating field/current system to produce torque.
- 11.2: Permanent Magnets in Electric Machines
- Of all changes in materials technology over the last several years, advances in permanent magnets have had the largest impact on electric machines.
- 11.3: Simple Permanent Magnet Machine Structures- Commutator Machines
- Figure 17 is a cartoon picture of a cross section of the geometry of a two-pole commutator machine using permanent magnets.
