Low cost electric disc rotor machine - has rectangular stator windings arranged on sides of disc rotor to increase output without increasing size

摘要

The machine has a stator with rectangular windings. The windings are formed such that the winding heads on the axis side are completely eliminated. In a preferred four pole machine, two north or two south magnetic poles are surrounded by a coil. Thus, both flexes are added to provide about 170 percent of the flux of a single pole with only about a 30 percent increase in length. The invention can be similarly applied to a two pole machine. A single-phase winding can be provided each side of the disc and these can be rotated relative to each other by 90 deg in the coil axis direction so that together they provide a two-phase system. USE/ADVANTAGE - For miniature electric machines. Simple and inexpensive to mfr.
