FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering, specifically to devices for energy conversion. Energy conversion device includes permanent magnets (1), holder (2) of magnets, cover (3), pinion (4) and housing (5), wheel (6), roller element (7) and coil (8). Plurality of permanent magnets (1) are placed in annular holder (2). Cover (3) in a ring shape whose width is greater than width of annular holder is secured to upper surface of annular holder (2) and has a magnet extending portion which is supported by a plurality of wheels (6). Wheels (6) are in contact with extension portion of cover (3) and bottom surface of hollow annular body (5), which is placed around coil. Gear wheel (4) in form of a ring is attached to cover (3) and annular holder (2). Between inner surface of housing (5) and gear (4) has rolling elements (7). External gear teeth (4) are engaged with external gear. Annular holder (2) of magnets can rotate easily even when number of permanent magnets (1) increases.
EFFECT: thus, energy conversion device can produce more power and thereby increase output power.
