An alternating current dynamo for a vehicle |
摘要 |
<p>According to the invention a copper loss of a stator winding (106) which is the largest loss of an alternating current dynamo for a vehicle is reduced by optimizing a balance of a ratio of a rotor outside diameter to a stator outside diameter, so that efficiency may be improved. Permanent magnets (112) are arranged between claws of an alternating current dynamo for a vehicle having a claw-shaped magnetic pole structure. A ratio of the rotor outside diameter to the stator outside diameter is set at less than 0.73. <IMAGE></p> |
