Abstract
A rotor drive motor includes permanently magnetized blades with the opposite poles spaced apart along a radial direction. Two or more stators have a U-shaped core and coil winding, the legs extending radially inwardly and against a housing shroud. Each of the stators are energized in alternately reversed polarities to cause the blades to be rotated continuously. The housing may include a conduit sealed thereto isolating the stators and power circuit components from hazardous materials.
