Abstract
The coil of this self-starting synchronous motor is parallel to its permanent magnet multiple pole rotor. The stator pole pieces are horizontal cheeks fastened to the core of the coil. The rotor is pivoted between these cheeks and encircled by stator poles formed by stampings from the cheeks bent at right-angles. A magnetic short-circuit is formed by a stator pole piece (13) touching the opposing pole face. The stator poles are of varying length. This forms a motor that has economic coil size, a magnetic shunt to improve flux distribution when adjacent to reduction gears and unequal pole lengths to cause the rotor to provide its own lateral thrust.
