- In mathematics, the
commutator gives an
indication of the
extent to
which a
certain binary operation fails to be commutative.
There are
different definitions...
- A
commutator is a
rotary electrical switch in
certain types of
electric motors and
electrical generators that
periodically reverses the
current direction...
- algebra, the
commutator subgroup or
derived subgroup of a
group is the
subgroup generated by all the
commutators of the group. The
commutator subgroup is...
-
material like
carbon press against the
commutator. The
brushes make
sliding contact with
successive commutator segments as the
rotator turns, supplying...
-
dynamo is an
electrical generator that
creates direct current using a
commutator.
Dynamos were the
first electrical generators capable of
delivering power...
-
speed and
torque of the motor. It is an
improvement on the
mechanical commutator (brushes) used in many
conventional electric motors. The construction...
- mathematics, the
commutator collecting process is a
method for
writing an
element of a
group as a
product of
generators and
their higher commutators arranged...
