The DC Motor
- The motor effect can be used to create a simple d.c electric motor
- The simple d.c. motor consists of a coil of wire (which is free to rotate) positioned in a uniform magnetic field:
Structure of a Simple D.C. Motor
A simple D.C. electric motor consists of a coil that rotates in a magnetic field, a split ring commutator and brushes
- This causes the coil to rotate since it experiences a turning effect
- The turning effect is increased by increasing:
- The number of turns on the coil
- The current
- The strength of the magnetic field
