What is a Commutator? - BYJU'S
What is a Commutator? Commutators are used in DC machines (DC motors and DC generators) universal motors. In a motor, a commutator applies an electric current to the windings. A …
What is the function of commutator? Physics Q&A - BYJU'S
The function of a commutator. The commutator ring of an electric motor reverses the direction of current flowing through the coil every time the coil barely reaches the vertical position during a …
What is a commutator - Mathematics Stack Exchange
The second way is to look at the commutator subgroup as a measure of how noncommutative a group is. A group is commutative if it has a trivial commutator subgroup (and highly …

Why is the commutator defined differently for groups and rings?
Jun 30, 2015 · The commutator of a group and a commutator of a ring, though similar, are fundamentally different, as you say. In each case, however, the commutator measures the …
How to show that the commutator subgroup is a normal subgroup
The commutator subgroup is generated by commutators. Show that the property of "being a commutator" is invariant under conjuation (in fact it is invariant under all automorphisms).
What is a DC Motor? - BYJU'S
Commutator and Brushes Commutator The commutator of a DC motor is a cylindrical structure that is made of copper segments stacked together but insulated from each other using mica. …
Commutators in $SL (2,\mathbb {Z})$ - Mathematics Stack Exchange
Jul 2, 2024 · For elements $g\in G'$ one defines its commutator length $cl (g)$ as the smallest number $N$ such that $g$ is the product of $N$ commutators of elements of $G$.
What is an AC Generator? - BYJU'S
A split-ring commutator is used for the conversion of the AC generator into the DC generator. When a slipt-ring commutator is used, it makes the current change its direction after every …
Understanding the commutator subgroup of the dihedral group
@NizarHalloun: Terminology issue: A "commutator" is an element of a group. You are talking about the "commutator subgroup," which is the subgroup generated by commutators.
