   Commutator
   Definition (advanced level) The commutator of two elements a and b of a group G is written [a,b] and is defined by: [ a , b ] = a . b . a - 1 b - 1 . <br /> In Quantum mechanics, if A and B are operators, then the commutator [A,B] of A and B is AB-BA.

    commutator
    an assembly of conducting members insulated from one another and from their supports, against which the brushes are maintained, enabling current to flow between a rotating winding and a generally stationary part of a circuit by sliding contact and also enabling commutation between the particular coils of the rotating winding

12. 
    Commutator
    The part of a DC motor armature that causes the electrical current to be switched to various armature windings. Properly sequenced switching creates the motor torque. The commutator also provides the means to transmit the electrical current to the moving armature through the brushes that ride on the commutator.

    commutator
    commutator, device used in an electric generator to convert the alternating current produced in the generator into direct current before the current is sent into an external circuit; it is basically a rotary switching device synchronized with the frequency of the alternating current. Commutators are...
