Generator-Equipped Engine and Method For Assembling Same

Abstract

An engine (10) equipped with a generator (20) is provided. The stator (24) fixed to the crankcase (12) includes a plurality of iron cores (32a to 321) arranged in the circumferential direction about the crankshaft (16), and coils (33) that are wrapped around the plurality of iron cores (32a to 321). The rotor (42) includes a flywheel (25) that is fastened to the crankshaft (16) by a fixing mechanism (28), and a plurality of permanent magnets (26a to 26f) fixed to the flywheel. The fixing mechanism (28) mounts the flywheel (25) on the crankshaft (16) in a position in which the center of one permanent magnet (26a) among the plurality of permanent magnets ¢26) coincides with the center point between two mutually adjacent irori cores (32a and 32b) among the plurality of iron cores (32a to 321) when the piston is at the top-dead-center or the bottom-dead-center.
