Abstract
An electrical machine has a permanent magnet component and a winding armature. The permanent magnet component is spaced apart for the winding armature. The winding armature includes a field excitation winding operative connected to the permanent magnet component. The field excitation winding is configured to selectively intensify and de-intensify the magnetic field of the permanent magnet for control of magnetic flux in the electrical machine.
Claims12
An electrical machine comprising:
- a permanent magnet component radially spaced apart from a winding armature;
- and
- a field excitation winding operatively connected to the permanent magnet component to selectively intensify and de-intensify a magnetic field of the permanent magnet component for control of magnetic flux in the electrical machine.
An electrical machine comprising:
- a permanent magnet component radially spaced apart from a winding armature, wherein the permanent magnet component includes a plurality of magnetic poles each with a respective embedded permanent magnet;
- and
- a plurality of field excitation windings, wherein a respective field excitation winding is housed in a respective pole shoe slot of the permanent magnet component to selectively intensify and de-intensify a magnetic field of the permanent magnets for control of magnetic flux in the electrical machine.
