Abstract
A dynamoelectric machine in the preferred form of a permanent magnet motor has an integral blade assembly associated with the rotor for the motor. The motor includes an enclosure with which the blade assembly mates. The blade structure/housing combination provides a labyrinth moving seal to protect the motor and associated motor control. The blade assembly and enclosure preferably are constructed from nonconductive material and provide a fully electrically insulated motor-fan assembly, which eliminates the need for certain grounding requirements. Blade construction is optimized easily to reduce audible sound in operation use. A method of assembly for a motor provides an integral blade assembly housing arrangement.
