Abstract
In a motor that includes bus bars each of which has an intermediate electrical path portion, end electrical path portions, and a main electrical path portion, the width of a portion of the intermediate electrical path portion at which the multiple end electrical path portions are formed between the main electrical path portion and an end portion of the intermediate electrical path portion is decreased from the portion at which the main electrical path portion is formed toward the end portion of the intermediate electrical path portion in such a manner that the width is decreased immediately after each intervening end electrical path portion by a unit width 'w' that is equal to the width of the end electrical path portion. Thus, it is possible to prevent the current density in the intermediate electrical path portion from being excessive so that the current density is maintained substantially constant, and to attain lighter bus bars, and, consequently, to attain a lighter motor.
