    摘要： A motor assembly having improved flux density includes a field assembly and an armature assembly rotatably received by the field assembly. The field assembly includes a plurality of like laminations stacked upon each other wherein each field lamination comprises a pair of substantially parallel bracket sides, and a pair of substantially parallel yoke sides which are substantially perpendicular to the pair of bracket sides. Corner pieces connect the yoke sides to the bracket sides wherein the corner pieces are angularly directed between about 40° to about 50° with respect to the yoke sides and the bracket sides. A yoke extends inwardly from each yoke side to form an armature opening therebetween for rotatably receiving the armature assembly. The bracket sides, the yoke sides and the corner pieces forming airflow areas therein, and the bracket sides, the yoke sides, (except at the yokes) and the corners all have substantially the same width dimension, such that the yoke sides, the bracket sides and the corners have substantially equivalent average field flux density ratios.
