Motors
Motor EffectA current in a field has a palm pushAmpere's lawDC Motors have constant switched force, Maximum torque at max distance flat to fieldComutators make Coil always the wrong way
aGenerators
Faraday Effect: Motor Effect separate + from -Moving conductor in a field is a Battery Lenz's Law - eddy currents maintain field and applies a drag force
aLenz's Law
Power
DC Generator is reverse DC motorAC Generator has windings on outside3 phase has constant torquePowerline insulation and lightening wires
aTransformers
Electricity > Mag Field > ElectricityTransformers - An electrically powered electricity generatorMore turns more voltsLaminations to hold field but stop current
aAC Motors
Universal - all coils - with core opposing outerInduction - Outer field drives eddy current in core rather than from slip rings
