The goal is to create a feasibility study! Contents of this study are 9 work packages, in which it is clarified whether the direct installation of one of 4 propulsion generator systems into a water wheel for the production of electrical energy, is technically possible and brings an increase in yield as well as a cost optimization. What's new here is the ability to integrate a high-poled segmented machine into a waterwheel with very low but constant speeds and high torques. Possible technical and economic advantages compared to conventional systems on the market are examined in the feasibility study. In the case of positive results, the immediate benefit to the customer is the cost advantage and the increased efficiency of the new system. Further advantages for the customer arise in the following areas: The construction of a machine room is no longer necessary due to the system integration in the water wheel. The low-noise drive system, lower lubricating oil volumes, short water drainage distances, good water-tightness of the water wheel for microorganisms and fish due to the low rotational speeds, as well as the water wheel, which is a scenic sight for the public, in which the new system is installed, also bring advantages in the approval process with himself. The feasibility study evaluates the following system solutions: Type A) A high-pole, permanently excited, direct-drive machine. Type B) A high-pole permanent-magnet machine with reduced transmission in 3 design variants (B1, B2, B3), which differ in the ratios and thus in the dimensioning of the electrical machine and the gearbox. The maximum output of the drive-generator system integrated in a water wheel is approx. 50 kilowatts. Waterwheels in general are efficient engines, but can handle only a limited amount of water, making it useful in many decentralized locations. At drop heights below 6 m, they are an interesting alternative to conventional turbines, since the acquisition costs, among other advantages, are considerably lower. Potential customers can self-utilize the recovered electrical energy, feed into the grid at the applicable green electricity tariff, or lease the site.
