commutators, plural;
  1. An attachment, connected to the armature of a motor or generator, through which electrical connection is made and which ensures that the current flows as direct current

  2. A device for reversing the direction of flow of electric current

  1. (commutator) switch for reversing the direction of an electric current
  2. In mathematics, the commutator gives an indication of the extent to which a certain binary operation fails to be commutative. There are different definitions used in group theory and ring theory.
  3. (Commutator (cryptology)) A plugboard, or control panel (the term used depended on the application area), is an array of jacks, or hubs, into which patch cords can be inserted to complete an electrical circuit. Control panels were used to direct the operation of some unit record equipment. ...
  4. (Commutator) The slotted copper segments at the end of the armature on an electric motor, which transfers the current from the brushes to the coils wound on the armature.
  5. (Commutator) A cylindrical device mounted on the armature shaft and consisting of a number of wedge-shaped copper segments arranged around the shaft (insulated from it and each other). ...
  6. (Commutator) Sliding electrical connection between motor windings and brushes.
  7. (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. ...
  8. (Commutator) The rotating part of a DC generator.
  9. (Commutator) The section of a DC motor which receives electricity from the brushes and sends it to a coil in the motor which acts to to provide a turning force via a magnetic force. ...

  11. (Commutator) an instrument used the measure the degree of the ships list.
  12. (Commutator) is also known as 'com' for short. It is the part of the rotor (the part inside which turns) which has three copper contacts for the brushes to run on. Keep clean and skim regularly for optimal efficiency and motor life.
  13. (Commutator) mechanical device in a brushed DC motor that passes current from the brushes to the windings.
  14. Algorithms of the form XYX'Y'. Link: Ryan Heise's Method Step 3, Jaap's Puzzle Page Theory
  15. are an intermediate concept. Commutators work sort of like algorithms, but they are much more versatile, and can generally be applied to many different situations, as opposed to an algorithm which is specific to only one case. ...
