The general working mechanism is the same for all motors:
Figure: Basic Principle of how Electric Motors Work. |
- An electric current in a magnetic field will experience a force.
- If the current carrying wire is bent into a loop, then the two sides of the loop, which are at right angle to the magnetic field, will experience forces in opposite directions.
- The pair of forces creates a turning torque to rotate the coil.
- Practical motors have several loops on an armature to provide a more uniform torque and the magnetic field is produced by electromagnet arrangement called the field coils.
