Abstract

Aluminum alloy ring shaped rotor with inlaid radial and lateral permanent magnets turns concentric to a three piece complementary ring shaped stator having one radial and-two lateral electromagnet windings to provide a brush less variable speed electric motor-generator designed for a particular power rating and to provide a virtual electromagnetic bearing in the "ON" mode of operation. Two radially and laterally supporting roller bearings interfacing the rotor and stator aluminum alloy castings to provide support of the rotor in the "OFF"
mode of operation. A "U" ring shaped molded tow part casting with reinforcing heat sink like struts is press fitted over the ring shaped motor-generator assembly, which has two lateral phalanges to provide an air and watertight assembly specifically adapted to the particular application. Two sealing ring cavities in the inner walls of the outer casting on each side and the ring shaped rotor are interfaced by a lubricated compression sealing ring. Inward pointing propeller blades are optionally an integral part of the rotor's molding process, or by separate and bolted-on to the inner surface of the rotor's rim. A watertight junction box for external electric connections is assembled over the shielding cover. Inline-pipeline electric motor-generator propellers can be specifically adapted to numerous applications for propulsion or the harnessing of energy including: air, water, oil and gas pipelines, the powering of vessels and the harnessing of ducted air, steam, river rapids, tidal, wave power and the like directly to electricity.

Description

TITLE: INLINE-PIPELINE ELECTRIC MOTOR-GENERATOR PROPELLER
MODULE
FIELD OF THE INVENTION
The present invention is directed to an inline-pipeline electric motor-generator propeller module specifically adaptable for propulsion and renewable energy harnessing directly to electricity, particularly adaptable to pipeline applications.
BACKGROUND OF THE INVENTION
Pipelines are costly to install and operate but a popular means of transporting fluids and gas throughout the world. The flow rate of air, water, oil and gas in - 15 pipelines particularly over long distances, is substantially reduced by friction losses. However this problem can be mostly overcome by adding propulsion modules at convenient locations along the way to maximize the volume while reducing pipe high pressure stress and installation costs. A very simple means to achieve this consists in inserting variable speed inline-pipeline electric motor-generator propellers modules interfaced to the pipeline at convenient intervals to achieve higher flow rates and.improved economics.
Another important feature of the inline-pipeline electric motor-generator is its inherent ability to function as propeller driven electric generator with immense areas of application for renewable energy harnessing. The harnessing of rivers, ocean currents, tidal power and ocean waves are distinct applications in which their energy can be channeled to the inward driven propeller. Potentially, the power output of river and ocean currents, tidal and wave power can be W tegrated into electricity and hydrogen fuel.
The basic operation principles of the inline-pipeline electric motor-generator propeller module have been described in the inventions applied for patent in CA: ROBOTIC TRANSPORTER, CA SN 2,342,430 - ROBOTIC

MOBILE, CA SN-2,342,431 - OCEAN CURRENTS SPACE STATION
CA SN-2,342,379 - HYDROGEN ROTARY GENERATOR CA SN
2,345,508 - ELECTROMAGNETIC WHEEL, CA SN 2,347,281. The present invention is yet another embodiment specifically adapted to provide important advantages to the mentioned industrial processes. As can be appreciated the propeller has been re-invented and its application potential and utility immensely expanded with embodiments of the inventions described by these invention disclosures.
SUMMARY OF THE INVENTION
An object according to a preferred embodiment of the inline-pipeline electric motor-generator propeller module of the present invention is to provide a reciprocal pipeline-interfacing module having inward facing propeller blades with the ability for propulsion and for the harnessing of energy.
Another object is to provide a motor-generator rotor in which the propeller blades may optionally be molded into a single casting.
Another object is to provide a motor-generator rotor in which the single molded casting propeller blades are adapted with shield covers for specific applications.
Another object is to adapt propeller blades of specific materials and designs according to the specific applications bolted down to the inner face of the ring shaped rotor.
Another object is to adapt two lateral interfacing phalanges to provide a match to the pipeline interfacing and protect the inline-pipeline electric motor-generator assembly from externally exerted forces.
Another object is to provide the invention in - numerous module formats and power ratings to suit the numerous areas of applications requiring different - 35 propeller blades, interfacing and stand designs.
The inline-pipeline electric motor-generator propeller module according to a preferred embodiment of the invention forms an electric powered propeller, which is adapted inline with the particular pipeline application by means of a phalange having sealing rings and compressed by either clamp rings or bolts to ensure a proper sealed fitting. A molded cover casting having a plurality of reinforcing struts interfacing the two lateral phalanges; which are rated to provide firm support of the external forces. Depending on the specifics of the application and power ratings, the need for a stand for the motor-generator propeller may be an adaptable option to suit the particular application.
Water oil and gas pipelines, are in addition to the harnessing of river currents and the powering of vessels among the numerous major areas of application for the embodiments of the present invention. The variable speed and power ratings that can be achieved with these modules provide very important technical and economic advantages over conventional methods.
From a technologic viewpoint, the electric motor-generator propeller rotor operates within a self contained electromagnetic field that forms a virtual electromagnetic bearing to provide long life and highly efficient operation. The "OFF" mode of operation suppo~~ting roller bearings and self-lubricating rotor air and watertight seals, are likely to provide for many years of maintenance free operation. The propeller blades design is specifically adapted to the particular application to achieve the best overall efficiency of -operation. The choice of materials and power ratings are other criteria to be chosen according to power, scale and specific applications. The variable speed of the brush less motor-generator and its ability to operate within self-contained electromagnetic fields in the power ON
mode are very important features for these applications.
