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.
Which circuit contain the brushes?
The circuit that contains the brushes is typically found in electric motors, particularly in brushed DC motors. Brushes are used to conduct electrical current between stationary and rotating parts of the motor, connecting the power supply to the rotor. They press against the commutator, allowing for the conversion of electrical energy into mechanical energy. In this setup, the brushes play a crucial role in maintaining the flow of electricity to the motor's windings.
Why does the armature-brushes arc excessively on an electric motor?
Excessive arcing between the armature and brushes in an electric motor can occur due to several reasons, including improper brush alignment, worn brushes, or low brush pressure. Poor electrical contact can lead to increased resistance, generating heat and causing arcing. Additionally, excessive armature current or voltage spikes can exacerbate the problem, leading to premature wear and potential damage to the motor components. Proper maintenance and ensuring compatible brush and commutator materials can help mitigate this issue.
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...

If you connected the test leads of an ohmmeter to the brushes of a DC electric motor what reading would you read?
If you connect the test leads to the brushes of a DC electric motor, you would typically measure the resistance across the armature circuit. This reading can help you determine the condition of the armature winding, the brushes, and the connections.
How do you Change electric motor brushes on Yamaha golf cart?
To change the electric motor brushes on a Yamaha golf cart, first disconnect the battery to ensure safety. Remove the motor from the cart and access the brush holder by unscrewing the cover. Carefully take out the old brushes and replace them with new ones, ensuring they are properly seated. Reassemble the motor, reattach it to the cart, and reconnect the battery.
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.
