What else can I help you with?
What part of a DC motor on the armature is responsible for connecting brushes to a coil?
commutator
How do you locate the neutral brush position in a dc motor?
leave the brushes of the motor at the position where the induced voltage is zero
Is the dc shunt motor does not have any brushes?
No. A d.c. 'shunt' motor is one whose stator's field windings are connected in parallel with its rotor windings ('shunt' is simply an archic term for 'parallel'); it does not mean that the rotor can function without brushes.
What is the main composition of the brushes of a dc motor?
Carbon Brush yang terbuat dari campuran tembaga dan Zinc atau lainnya.
Does a ac generator have a brush?
AC generators (alternators) usually have a dc supply to the rotor coils, supplied through slip-rings with carbon brushes. Because the slip-rings can be made very smooth the life of the brushes is greatly extended when compared with brushes on the commutator of a dc motor or an ac commutator motor. Cars generate electrical power with a three-phase AC alternator, connected directly to the battery through rectifier diodes. The alternator voltage is controlled by the voltage regulator, which works by controlling the dc supply to the rotor.
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 is the function of pole shoes of dc motor?
To overcome the sparking at brushes.
What are the Difference between dc motor and dc generator?
a motor Will do work by consuming power a generator is just the opposite
What is commutation in DC machines?
It is the process of conversion of generated ac voltage into the armature of a dc generator to dc voltage at the terminal of the dc generator by use of pair of brushes and commutator. OR It is the process of conversion of given dc voltage at the terminal of the dc motor to ac voltage in the armature windings in a dc motor by use of pair of brushes and commutator.
What part of a DC motor should be inspected most frequently?
Commutator and brushes.
What part of a DC motor on the armature is responsible for connecting brushes to a coil?
commutator
Why are the brushes of DC motor motor made of carbon rather than copper?
Carbon is much stronger and because the motor commuter is spinning copper brushes will wear off quickly.
How do you locate the neutral brush position in a dc motor?
leave the brushes of the motor at the position where the induced voltage is zero
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.
Explain how to locate the neutral brush position in a dc motor?
leave the brushes of the motor at the position where the induced voltage is zero
What are the parts of motor?
Armature Commutator Brushes Axle Field Magnet DC power supply
What are the parts of an electric motor?
