Difference between Electronic Commutator and Mechanical Commutator:
The difference between Electronic Commutator and Mechanical Commutator is given in table below
| Sl no | Electronic Commutator | Mechanical Commutator |
| 1 | Power electronic switching devices are used in the electronic commutator. | The commutator is made up of commutator segments and mica insulation with carbon or graphite brushes. |
| 2 | Commutator arrangement is located in the stator. | Commutator arrangement is located in the rotor. |
| 3 | Number of switching devices is limited to 6. | The number of commutator segments are very high. |
| 4 | No sparking. | Sparking takes places. |
| 5 | Voltage can be controlled by PWM techniques. | Difficulty to control the voltage avaibale across tappings. |
