commutator definition

  • noun:
    • A cylindrical arrangement of insulated metal bars attached to the coils of a direct-current electric engine or generator, offering a unidirectional present from generator or a reversal of existing in to the coils of the motor.
    • Mathematics In a commutative or noncommutative team, an element of the shape ghg-1h-1 in which g and h tend to be aspects of the team. If g and h drive, the commutator could be the identity element.
    • a power switch, in a generator or engine, that occasionally reverses the direction of an electrical present
    • (of an organization) an element of the shape ghg−1h−1 in which g and h tend to be components of the group; it really is corresponding to the team's identity if and just if g and h drive
    • (of a ring) some the shape ab-ba, in which a and b are components of the band, its exactly the same as the band's zero factor if and just if a and b drive
    • A piece of equipment useful for reversing the path of a power current; an attachment to particular electrical devices, through which alternating currents are made to be constant or even have a similar course. It may possibly be connected to the end regarding the spindle of an electric engine, in which a brush is in contact sequentially with all the parts of the spindle that conduct present towards different windings of this motor.
    • An apparatus utilized in experience of many electric instruments for reversing the currents through the battery pack without changing the arrangement associated with the conductors from the poles: since, Bertin's commutator.
    • A contrivance for different the effectiveness of an electric up-to-date by bringing either a percentage or perhaps the entire regarding the voltaic cells in a battery to the circuit.
    • In electricity, that section of a continuous-current dynamo-electric machine which, by revolving touching the brushes, turns or directs the electric actions within the armature coils associated with machine so as to make the current while the current when you look at the additional circuit constant.
    • In photography, a tool for immediately effecting the publicity of a number of photographic plates at various predetermined instants during a complete eclipse of sunshine.
    • switch for reversing the path of an electric current
    • A cylindrical arrangement of insulated material pubs attached to the coils of a direct-current electric engine or generator, providing a unidirectional existing through the generator or a reversal of existing to the coils for the engine.
    • Mathematics In a commutative or noncommutative group, an element of the proper execution ghg-1h-1 in which g and h tend to be aspects of the team. If g and h travel, the commutator could be the identification factor.
    • a power switch, in a generator or engine, that periodically reverses the course of an electrical current
    • (of a bunch) some the proper execution ghg−1h−1 where g and h are elements of the group; its equal to the group's identification if and just if g and h travel
    • (of a ring) some the shape ab-ba, where a and b are components of the band, its identical to the band's zero element if and only if a and b commute
    • an item of apparatus useful for reversing the direction of an electrical current; an attachment to certain electrical machines, through which alternating currents are made to be continuous or even have the same path. It may be connected to the end of this spindle of an electric engine, in which a brush is in contact sequentially using the areas of the spindle that conduct present into different windings of the motor.
    • An apparatus utilized in connection with numerous electrical tools for reversing the currents from the battery pack without altering the arrangement regarding the conductors from the poles: because, Bertin's commutator.
    • A contrivance for different the effectiveness of an electric up-to-date by bringing either a portion or perhaps the entire regarding the voltaic cells in a battery into the circuit.
    • In electrical energy, that element of a continuous-current dynamo-electric device which, by revolving in contact with the brushes, transforms or directs the electric activities when you look at the armature coils regarding the device to be able to make the present as well as the current when you look at the outside circuit constant.
    • In photography, a device for automatically effecting the visibility of several photographic dishes at various predetermined instants during an overall total eclipse of this sunlight.
    • switch for reversing the path of an electric present
