摘要： A fan end bracket for a motorized fan assembly has a plurality of curvilinear tapered air passages. Each air passage includes a flow port, such that air being moved by a rotating fan assembly is directed through the air passages and the flow ports. A skeletal motor assembly is affixed to one side of the end bracket such that the motor shaft is disposed through a shaft aperture in the end bracket. A rotating fan member is affixed to the motor shaft adjacent to the other side of the end bracket. A shroud member is provided to shroud the rotating fan member so as to cause the flow of air to be directed through the air passages. A baffle plate is interposed between the rotating fan member and the end bracket. The baffle plate includes a plurality of curvilinear scallops which correspond to the air passages in the end bracket. An effective flow port is created between the scallops of the baffle plate and the tapered ramp surfaces of the end brackets so the size of the effective flow port may be adjusted by merely changing the baffle plate so as to optimize the flow and pressure parameters of the fan for a particular motor size.

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.

摘要： A motor assembly having improved flux properties comprises a rotor lamination rotatably disposed within a field lamination. The field lamination comprises a constant cross-sectional dimension, and is configured to provide a pair of opposed, tapered yokes that provide constant impedance to the rotor lamination. The rotor lamination includes a plurality of spaced teeth that are dimensioned so that taper of the yokes changes by a factor of the width of one of the teeth, thereby reducing the material needed to adequately carry the magnetic flux of the rotor lamination.
