VCE Physics — Unit 3 AOS 3

DC Motor — Flashcards & Quiz

A DC motor converts electrical energy into mechanical rotation by using the motor effect — a current-carrying conductor in a magnetic field experiences a force F = BIL sinθ. VCE Physics Unit 3 AOS 3 expects you to explain the role of the split-ring commutator and describe how torque varies as the coil rotates.
