Crank-shaft electrical power generator e.g. for automobile combustion engine, uses permanent magnet as counter-weight for reducing crank-shaft vibrations

摘要

A crank-shaft generator has at least one permanent magnet (16) and at least one conductor loop, in which the permanent magnet is arranged on a rotary crank-shaft and the conductor loop is fixed in the immediate vicinity of the crank-shaft. At least one permanent magnet (16) partly forms counter-weight (20) in order to reduce vibrations of the crank-shaft (10).
