. The first topic is steady-state three-phase inductionmotor theory. The presented motor theory is based on the equivalent circuit model.5 Thismodel requires rotor and stator resistances, rotor and stator leakage reactance, and the motormagnetization reactance parameters. Locked-rotor and no-load tests find these parameters.Solving the equivalent circuit model gives the rotor and stator currents as a function of motorslip, s. After rotor current is obtained, the rotor developed power and motors losses can be foundfor any operating point. The tutorial introduces the motor developed torque equation anddemonstrates how to plot the motor torque-speed curve from the developed power found fromthe equivalent circuit.Machine load factor and efficiency

generation, transmission and deliveryare the focus of this paper.Electric energy has been used since the1890’s when the world entered the Age of Electricity.Since then the world has moved through a series of these ages: 1890’s – The “Age of Electricity” begins with the lighting of the Chicago World’s Fair in 1893, and completion of the first long distance transmission line moving hydro-electric power from the mighty Niagara Falls to Buffalo in November of 1896. 1930’s – The “Industrial Age” begins with electricity, power tools, and automation in factories, at the end of the Depression. Industrial productivity, measured in terms of output per unit of labor, makes major gains during this period. This results

overarching goals: engage students inlearning and facilitate the transition to college life. In the College of Engineering, we seek toprovide a small class experience that provides them with a meaningful and interestingintroduction into some aspect of engineering practice. Class size is limited to 20 students andnearly all FYS’s are taught by regular faculty members. There are over sixty different seminartopics in engineering; for more information consult the web site at www.engr.psu.edy/fys.The Solar Racers FYS evolved from projects used in a three-credit technical elective on solarenergy taught by the author at Penn State Harrisburg since the 1980’s.

tried toproduce a FC that could convert coal or carbon to electricity directly. These attempts failedbecause not enough was known about materials or electricity. In 1932, Francis Bacon developedthe first successful fuel cell. He used hydrogen, oxygen, an alkaline electrolyte, and nickelelectrodes. In 1952, Bacon and a co-worker produced a 5-kW fuel cell system. The large boost inFC technology comes from NASA. In the late 1950’s NASA needed a compact way to generateelectricity for space missions. Nuclear was too dangerous, batteries too heavy, and solar panelstoo cumbersome. The answer was fuel cells. NASA went on to fund over 200 research contractsfor fuel cell technology. Both the alkaline and polymer electrolyte fuel cells have

The design team used Bloom’s Taxonomy7 as a guideline in this, and similar goalshave been set for other middle school engineering modules8. Kits developed to date include HeatTransfer, Chemical Energy, Electrical Energy, Solar Power, and Wind and Water Power.Instruction Manual: The instruction manual consists of a guide sheet, lesson plans, handouts,and assessment forms. The contents of the Instruction Manuals are available online so teacherscan browse and decide which kit(s) to use
