75 Segments Commutator Mechanical Commutator For Various Motors


The functions of the commutator is given below:

  1. To facilitate the collection of current from the armature conductors.
  2. To convert internally developed alternating EMF to unidirectional EMF
  3. 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 CommutatorElectronic 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.
