1.Just like in a transformer, the three main sources of loss in an electric motor are: 1-Conduction losses (aka joule losses, or I²R losses) from the windings 2- Hysteresis losses in the steel 3- Eddy current losses in the steel core, as well as in any other metals in the rotating field In motor controls, a major source of research (both in industry and academia) is finding ways to reduce those losses in an existing motor just by changing the...

ADVANCE STUDY ASSIGNMENT: COULOMB'S LAW PURPOSE of tl of this exercise is to become familiar with the force between electric point charges which is descrbed by Coulomb's law. In particular, we will investigate the force's inverse-square dependence on separation distance between charges. DISCUSSION A basic characteristic of electric charge is that charges exert forces on each other, like charges positive-positive and negative-negative) repel each other while opposite charges (positive- and constitute a Newton's third-law pair; that is, they are equal...

Tethers are long dangling wires that use the velocity of a spacecraft through the Earth's magnetic field to generate electrical power. Alternatively, electrical currents pushed through the tether might be used to change the spacecraft velocity for either propulsion or for braking and reentry. Several 'space tether experiments have been flown to investigate the possible use if Faraday's law for power generation and/or propulsion. Examples are the 1996 joint US/Italy effort to deploy a 20 km tether from one of...
