Rotor for a magnetic generator

摘要

A rotor is proposed for magnetic generators, especially for flywheel magnetos of internal-combustion engines, in which a pole ring (14) having magnetic poles which alternate in the circumferential direction is inserted into a rotor bell (11). The inner outline surface (13) of the rotor bell (11) has a larger diameter in the front region, located towards the open end (11b), than the rear region, located towards the base (11a). The pole ring (14) is in this case pressed axially into the rotor bell (11) as far as the rear region (Figure). <IMAGE>
