homopolar generator [¦hä·mǝ`pō·lǝr `jen·ǝ´rād·ǝr] ELECTRONICS A direct-current generator in which the poles presented to the armature are all of the same polarity, so that the voltage generated in active conductors has the same polarity at all times; a pure direct current is thus produced, without commutation. Also known as acyclic machine; homopolar machine; unipolar machine. |
