75 Segments Commutator Mechanical Commutator For Various Motors
The functions of the commutator is given below:
Mechanical Commutator Vs Electronic Commutator:
Mechanical Commutator | Electronic Commutator |
It is made up of commutator segments and mica insulation. Brushes are made up of carbon or graphite. | Power Electronic switching devices are used in the commutator. |
Commutator arrangement is located in the rotor. | Commutator arrangement is located in the stator. |
Shaft position sensing is inherent in the arrangement. | It requires a separate rotor position sensor. |
Number of commutator segments are very high. | Number of switching devices is limited to 6. |
Sliding contact between commutator and brushes. | No sliding contacts. |
Sparking takes place. | There is no sparking. |
It requires a regular maintenance. | It requires less maintenance. |
Difficult to control the voltage available across tappings. | Voltage available across armature tappings can be controlled by PWM techniques. |
Highly reliable. | Reliability can be improved by specially designed devices and protecting circuits. |
