A Czech inventor offers novel, patented solution of the steam-powered rotary motor with a high torque under licence agreement.

There have been multiple attempts to design and construct practical steam powered motors so far, but the attempts ended up with serious challenges. The motor on offer overcomes the challenges, some of which are indicated below. It has been designed by a mechanical engineer with a vast practical experience and knowledge in mechanical engineering. Currently, he disposes of many technical calculations and drawings and also carried out tests with several prototypes. Existing steam motors (motors with crankshaft) have disadvantage of relatively high energy losses and thus low efficiency. On the other hand, it is much easier to manufacture them than turbines. Turbines have much better efficiency but high production costs. In addition, their operation is economical with higher outputs. Generally speaking, the inventor´s general focus is on the markets with motors where turbines are not competitive because of their production costs. The motor is ecological and operates on steam produced by a boiler that uses various fuels like economical light heating oils (TOEL), biogas, natural gas, recycled oils and/or wood waste. Its modular concept allows to add more rotors, the inventor envisages motor with 6 rotors as the most efficient in terms of its performance. Existing issues of the steam motors - Loses of energy during its reversible movement - working cycle starts on the shortest arm of the power - dynamic balance of the crankshaft is difficult - relatively high size of the motor In comparison, the novelty can be characterized as follows: - rotating piston together with cogwheel - working cycle starts on the longest arm of the power - summation of the rotational and sliding powers - increase of the torque during transmission on the central axis of the motor - double acting operation and synchronous work of both rotors - absolute dynamic counterbalance - small size of the motor - low center of gravity Selected applications of the novelty a) electric vehicles´ charging infrastructure: steam powered charging points – eliminate problems associated with electricity production and transmission to various distances. Waste heat can be utilized for heating of adjacent properties as a system is closed so the condensed steam returns back to the system. b) Electricity generators c) Smaller autonomous electricity production systems d) Standby power supplies to bridge electricity failures and where is no immediate need to restore functioning (hospitals, etc.) e) Novel drive substituting combustion engines in smaller river or coastal boats where need of high torque during low speed is desirable. No starter, no clutch, no gearbox are needed. Current status Currently, the inventor has constructed new, functional prototype that is potentially ready to be used in concrete products. The motor is in stainless steel version with two elliptic rotors 120/80 mm width 58 mm with bronze sliding surface. It will be tested, but only with one rotor in order to identify impact of the heat dilatations on its movement, consumption of the steam per one rotor related to specific revolutions. Then, it will be possible to identify needed wattage per one rotor. For purpose of demonstration, the motor will be available with two rotors. The inventor seeks partners capable to utilize the invention and convert it into concrete commercial applications. License agreement will be provided.
