CONTACTLESS SYNCHRONOUS GENERATOR Russian patent published in 2004 - IPC

FIELD: electrical machines; contactless synchronous generators with built-in rectifier mainly for automotive engineering.

SUBSTANCE: novelty is that contactless synchronous generator incorporating front and rear end plates, stator in the form of stack carrying running winding, rotor with set of claw-shaped poles, built-in rectifier, and shaft-mounted rotor field winding whose leads run to slip rings has its shaft made in the form of hollow structure with radial holes, one of shaft extensions being provided with plug, and other one communicates with cooling system port; in addition slits are made at bends of claw-shaped poles and radial holes are provided in front and rear end plates.

EFFECT: enhanced performance characteristics due to reduced input power, reduced mass, improved thermal characteristics.
