Parts of a Electric Motor
- Insulated Copper wire: A rectangular coil of wire ABCD
- Magnet Poles: A magnet as placed above ie North Pole and South Pole. This creates a magnetic field as shown above.
- Split Rings: Two disjoint C-shaped rings P and Q. It acts as a commutator (which can reverse the direction of current)
- Axle: The split rings are placed on the axle which can rotate freely.
- Brushes: The outside of the split rings are connected to conducting brushes X and Y.
- Source Battery: To source current.
Working
When the current begins to flow, current flows through brush X, then A to B, B to C, C to D and then to brush Y and into the battery.
Now applying Fleming's Left Hand Rule to wire AB, Current is along AB, Magnetic Field is as shown (North-> South), the motion of the wire is downwards.
Now applying Fleming's Left Hand Rule to wire CD, Current is along CD, Magnetic Field is as shown (North-> South), the motion of the wire is upwards.
