A novel design and manufacturing of light-weight high-strength composite impellers with integrated motor and bearing is introduced. It is based on winding or weaving endless fiber material on a commercially available winder. This concept may be applied for compressors, pumps, turbines, propellers, or jet propulsion devices (Fig. 1). By interweaving electrical motor components, constructions without a shaft, or shaft sealing are possible. Also, the active motor elements can be positioned outside of the fluid stream. Besides the low cost of construction, one of the main advantages to this design is the integration of electrical motors in the turbo-wheels. This allows for the easy implementation of multiple counter-rotating turbomachinery stages in not only axial configurations, but also mixed flow configurations as well. The integrated motors are typically variable speed motors.
