  • What is a Commutator? - BYJUS
    The commutator segments and brushes should maintain a continuous moving contact for the better transformation of the current More than one coil is used in DC machines to avail larger output values Now, let us consider a DC motor in which the width of the commutator bars is equal to the width of the brushes
  • 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 noncommutative if the commutator subgroup is the entire group) But we can then ask if the commutator subgroup is abelian And if not, if it's commutator subgroup is abelian
  • What is the function of commutator? Physics Q A - BYJUS
    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 rotation Commutators and brushes are employed in all DC generators and DC motors
  • How to show that the commutator subgroup is a normal subgroup
    $\begingroup$ Ted's argument is from L Myers, "Normality of the Commutator Subgroup" Math Mag 68 (1995), p 49 The same slick method shows any subgroup containing the commutator subgroup is a normal subgroup $\endgroup$ –
  • The commutator of two matrices - Mathematics Stack Exchange
    The commutator [X, Y] of two matrices is defined by the equation $$\begin{align} [X, Y] = XY − YX \end
  • What is commutator? Physics Q A - BYJUS
    A commutator is a piece of equipment linked to the armature of such a motor as well as a dynamo that makes an electrical linkage as well as guarantees the amount of current flowing via direct current Function of commutator
  • Commutator of $x$ and $p^2$ - Mathematics Stack Exchange
    Stack Exchange Network Stack Exchange network consists of 183 Q A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers
  • Why is the commutator defined differently for groups and rings?
    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 "extent" to which two elements fail to commute
  • What are operators, commutators and anti commutators algebra?
    What are commutator and anti commutator of two operator $\hat A$ and $\hat {\vphantom{A}B}$? operator-theory;
