Product Description
75 Segments Commutator Mechanical Commutator For Various Motors
The functions of the commutator is given below:
- To facilitate the collection of current from the armature conductors.
- To convert internally developed alternating EMF to unidirectional EMF
- To produce unidirectional torque in case of motors.
- The commutator is of cylindrical shape.
- It is made up of wedge-shaped copper segments of high conductivity.
- They are insulated from each other by a thin sheet of mica.
- Each segment is connected to armature conductors by means of a copper strip( which is known as riser).
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. |
