Abstract

An electric motor 100 includes a motor housing 10 and a hollow rotor 20 configured to rotate within and be driven by a stator 30 contained within the motor housing 10. The motor housing is characterized by a largest cross-sectional area of the motor housing 10 and the hollow rotor 20 defines a flow channel characterized by a smallest cross-sectional area of the flow channel, where the smallest cross-sectional area of the flow channel is at least 25% of the largest cross-sectional area of the motor housing 10. The hollow rotor 20 has a first end portion defining a fluid inlet 27, and a second end portion defining a fluid outlet 29 where the fluid inlet 27, the flow channel 25 and the fluid outlet 29 is configured to allow passage of a fluid from the fluid inlet to the fluid outlet via the flow channel 25. Also claimed is a machine for electric power generation including a generator having the same fluid flow channel and relative cross sectional areas as described for the electric motor (fig 9).
