  1. commutatornoun

    switch for reversing the direction of an electric current

GCIDE

  1. Commutatornoun

    A piece of apparatus used for reversing the direction of an electrical current; an attachment to certain electrical machines, by means of which alternating currents are made to be continuous or to have the same direction. It may be attached to the end of the spindle of an electric motor, where a brush is in contact sequentially with the parts of the spindle that conduct current to the different windings of the motor.

Wiktionary

  3. commutatornoun

    (of a ring) an element of the form ab-ba, where a and b are elements of the ring, it is identical to the ring's zero element if and only if a and b commute

  1. commutator

    A commutator refers to either of two mathematical concepts, one in group theory and one in vector analysis. 1) In group theory, a commutator is an element of a group generated when calculating the product of two elements in a specified order and multiplying the result by the inverse of the order. Specifically, if 'a' and 'b' are elements of a group, the commutator is usually expressed as [a,b] = a*b*(a^-1)*(b^-1). 2) In vector analysis, a commutator is an operation on two vector fields that results in another vector field, commonly used in the study of differentiable manifolds. In physics and electrical engineering, a commutator is a rotary electrical switch in certain types of electric motors or electrical generators that periodically reverses the current direction between the rotor and the external circuit.
