초록

The invention relates to a starter-generator machine (10) for starting turbine type aircraft engines. The machine combines an induction motor with a synchronous samarium cobalt generator. In the machine, a rotor-shaped stator (22) is fixed and positioned inside a squirrel-cage induction rotor (18) which has an array of samarium-cobalt magnets (24) attached on the outer diameter thereof. The compound dual machine operates as a starter by using the induction rotor to accelerate the permanent magnet rotor, and thus the aircraft engine via a drive pinion (34...
