My friends say I'm just one goat away from never getting married.I make goat soap like a pro, channeling my inner "Little House on the Prairie" on Friday nights. Okay, I see their point . . .But small towns aren't exactly a dating paradise, and eligible bachelors under forty? About as rare as a unicorn sighting.

Magnetic gears and magnetic geared permanent magnet (PM) machines have recently been emerging as a new class of future electromechanical machines which can address problems of low-speed power generators. A magnetic geared generator integrates a magnetic gear with a low torque, high-speed PM generator to produce a compact low-speed,high torque machine with the advantages of a direct drive PM machine and magnetic gear.

In 1892 Charles Heisler received a patent for a new kind of geared locomotive. Equipped with twin canted cylinders, the engine utilized a drive shaft to power outboard axles and connecting rods to power the inboard axles. As a result of this 'vee-twin' arrangement, the Heisler was one of the fastest geared steam locomotives, providing more power with lower operating costs. Over 600 Heislers were produced from the 1890's until 1941, when the Heisler Locomotive Works closed its doors.

Analysis of the gear system as rotors is a very challenging problem because the system is a composite rotor; therefore possesses very complicated dynamic behavior. For example, the whirling motion and critical speed of the system has to be found by considering all the rotors in the system as well as interactions between them, which makes the solution process as well as proper interpretation of the solution extremely complicated.
