commutator

First, let us see why this is called a commutator.

However, we needed only a little for the commutator bars.

Now you'll never get a true surface with a commutator stone.

She indicated the commutator with a jerk of her head.

The above definition of the commutator is used by some group theorists.

The commutator must become larger and more robust as the current increases.

A direct current can be taken from the commutator.

However, the product of two or more commutators need not be a commutator.

The negative aspect is the maintenance and short life problems caused by the commutator.

A commutator is a common feature of direct current rotating machines.

As the name implies, the machine had three brushes in contact with the commutator.

But the notion of the commutator is very powerful for finding useful simple processes.

The brushes are spring loaded contacts pressing against the commutator.

Unlike a dynamo, there is no commutator and so they cannot produce direct current.

In general, the commutator of any two derivations and is again a derivation.

The different brush types make contact with the commutator in different ways.

Typically the brush is wide enough to span 2.5 commutator segments.

Commutator identities are an important tool in group theory.

To make this work, the cord is attached to a rotating contact called a commutator block.

I aimed a fine D-beam at the 4 leads on the commutator and cut through them.

Without coils or commutator, the motor began to turn.

Motors which have a commutator can suffer from sparking at the brushes.

The commutator of the motor creates sparks which in turn produce ozone.

You can see that the commutator is simply a pair of plates attached to the axle.

To change the direction of the electric current, he constructed a commutator of his own.
