Origin of 'commutator'
Main points about word origin
- The term originates from Latin, where 'commutare' means 'to interchange', relating to its function of switching currents.
- The word 'commutator' has been in use in English since the late 19th century, primarily in electrical engineering contexts.
- It is related to other words such as 'commute', meaning to exchange or switch places.
The term 'commutator' originated in the early 19th century from the Latin word 'commutare,' meaning 'to change completely.' The concept of the commutator was first introduced by William Sturgeon in 1832, enhancing the efficiency of electric motors.
