Abstract:
Electromagnetic devices and near field plates for three-dimensional magnetic field manipulation are disclosed. In one embodiment, an electromagnetic device includes a rotor, a stator, and a magnetic field focusing device. The rotor may include a rotor body and a plurality of radially extending rotor poles. The stator may include a plurality of stator poles radially extending inwardly from a stator body toward the rotor body. Each stator pole may have a magnetic flux generating device and a stator pole tip, wherein an air gap may be located between each stator pole tip and each corresponding rotor pole. The magnetic field focusing device is coupled to at least one stator pole tip and produces a magnetic field profile having at least one concentrated magnetic flux region proximate the stator pole tip. The magnetic field focusing device twists the magnetic field profile by an angle α.
