Document Type and Number:
WIPO Patent Application WO/1998/033263
Kind Code:
A1
Abstract:
A stator (1) which faces the outer surface of a rotor (6) through a gap is made of die-casting aluminum and is provided, in its circular inner face, with a plurality of slots (3) to install windings for leading out the generated output with notches (2) being formed from the bottoms of the slots (3) to the outer surface of the stator (1), and a yoke (4) which, being formed of magnetic material, abuts against the outer surface of the stator (1) and surrounds it. The rotor (6) is made of die-casting aluminum on the outer surface of a rotary shaft (5) and is provided with permanent magnets (7) which are fixedly mounted to the outer surface of the rotor (6) and are let to face the inner surface of the stator (1) through a small gap. This generator is further provided with a means for linearly developing the stator (1) and rotor (6) and a means for holding the rotor (6) as a movable member (1a), keeping it while reciprocating in the stator (1) through a gap.
