Applications of the Motor Effect (HSC SSCE Physics): Flashcards

Kinetic energy into electrical energy

Slip rings

$\varepsilon_{\text{max}} = 2\pi fnBA$

$\varepsilon_{\text{rms}} = \frac{\varepsilon_{\text{max}}}{\sqrt{2}}$

Commutator

Converts alternating EMF to pulsed DC output

Stator (stationary) and rotor (rotating)

Electromagnetic induction with no direct current to rotor

No commutator or brushes, low maintenance

$\Phi = nBA\sin(2\pi ft)$
