The commutator of two elements g and h of a group G is the element [g h] = g−1h−1gh This element is equal to the group&#39s identity if and only if g and h commute (from the definition gh = hg [g h] being [g h] equal to the identity if and only if gh = hg ) The set of all commutators of a group is not in general closed under the.

1 Komutator berfungsi sebagai kontak geser antara carbon brush dengan jangkar (armature) yang berputar untuk memberi atau mengambil arus listrik ke mesin elektrik 2 Komutator berfungsi sebagai saklar pembalik (reversing switch) Ketika ujung akhir armature melewati carbon brush Komutator akan mengaturnya dari satu sirkit ke sirkit yang lain.

The commutator of two group elements and is and two elements and are said to commute when their commutator is the identity element When the group is a Lie group the Lie bracket in its Lie algebra is an infinitesimal version of the group commutator For instance let and be square matrices and let and be paths in the Lie group of.

Commutator from Wolfram MathWorld

A commutator is a rotary electrical switch in certain types of electric motors and electrical generators that periodically reverses the current direction between the rotor and the external circuit It consists of a cylinder composed of multiple metal contact segments on the rotating armature of the machine.
