Source sentences:
text: The rotor magnetic field may be produced by permanent magnets, reluctance saliency, or DC or AC electrical windings.
text: When a current passes through a coil, the coil becomes magnetized, and if it's attached to a shaft and suspended in the field generated by a permanent magnet, the opposing magnetic forces create enough force to turn the shaft.
text: The armature windings interact with the magnetic field (magnetic flux) in the air-gap; the magnetic field is generated either by permanent magnets, or electromagnets formed by a conducting coil.
text: This field may be generated by either a permanent magnet or a field coil.
text: In an ideal brushless drive, the strength of the magnetic field produced by the permanent magnets would be adjustable.
text: Also, the magnetic field produced by the permanent magnets isn’t adjustable.
