Brushes transfer electricity to the commutator which is connected to the winding on the armature. The brushes and commutator form a electrical connection that is good when the brushes are stationary and the commutator is spinning. The commutator on a DC motor is sectioned to power different windings at different times, creating moving field necessairy to pull the armature off a direct current.

What allows the current to enter the electronromagnet in an electric motor?
The resistor allows current to enter the electromagnet in an electric motor. The resistor regulates the amount of current that enters the electric motor.
Electric motor parts?
Electric motor parts are pieces of electric motors. Some examples of electric motor parts are: bearings, carbon brushes, gasket materials, pumps, soft starters, and terminal boxes.
Why you use brushes for single phase induction motors?
There no brushes in an induction motor. The rotor is independent and is a short-circuited cage of parallel bars.
What does the brushes and commentator in a D C motor do?
i have never heard of a commentator in a motor, think you may be mistaking that word. inside an electric motor you have a stator and windings, as polarity changes it spins the stator and the brushes transfer the charge to the device being used.. I think they meant commutator. If you break an electric motor down to 2 parts, you have a commutator and an armature. the armature being the shaft that basically floats on bearings, and the commutator being the hull where the stator is. (and there is such thing as a brushless electric motor.) the stator does not spin. that is the term used for the magnets that pull the electric field supplied by the brushes. To make even more simple, imagine a shaft floating on bearings with 2 magnets on it, one positive and one negative ( the armature) and this shaft is inside of a ring of electricity the is flowing in one direction, its going to pull the negative and push the positive (the commutator) and cause the armature to spin.
What is the difference between a two brush and a four brush starter motor?
the reason for brushes is to makethe motor revolve. The more brushes probably make a more powerful starter motor
Can you harm an electric rotory tool by using the wrong brushes?
Yes, If you use brushes of the wrong hardness. Harder carbon brushes eat into the commutator of a motor ultimately ruining it.
In an electric motor where is the location where the current enters the electromagnet?
The commutator and brushes...

What household items have motors?
umm well there is a bagle that has a motor in it and there is a car and there is electric tooth brushes
What are the parts of an electric motor?
Armature Commutator Brushes Axle Field Magnet DC power supply
What are the parts of an electric engine?
Actually an electric motor is a simple device. It contains a housing, wiring, brushes, electrical connections, and an electrical coil.
What are two reasons for motor failure?
Assuming you mean electric motors, the causes for failure include seized bearings and worn brushes. If the bearings or bushings are seized, the motor may fail. Most electric fans have thermal fuses, so if the motor seizes and overheats, the fuse blows. If the brushes are worn, then the motor is no receiving electricity and thus cannot turn.
What electric motor does an electric car use?
A electric car uses either a DC or AC motor. Typically they use DC motors.
Why you use brushes for single phase induction motors?
There no brushes in an induction motor. The rotor is independent and is a short-circuited cage of parallel bars.
What are brushes with reference to DC motors?
Bushes, with reference to DC motors is a brushed DC motor which is a motor that designed to run from a direct current (DC) power source. This type of motor is an internally committed electric motor.
What motor is use in portable fan?
An electric motor.
