This section is part of the HSC Physic syllabus Module 6: Electromagnetism under Applications of the Motor Effect.
Motors are the core of how so many mechanical systems work in today’s world. So let’s learn a little more about how a DC motor works. We’re going to cover the following information about a DC motor:
- Back EMF in a DC motor
Back EMF in a DC motor
Back EMF comes from the conservation of energy. BackEMF is a force created to oppose a change in flux. This usually happens when a motor starts up.
