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
Why are brushes staggered in dc motor?
To avoid sparking they need to be placed at zero point
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 are Interpol winding's in a dc motor?
Interpol winding in a DC motor refers to the additional winding placed between the main field windings to improve magnetic field distribution and enhance performance. These windings help reduce armature reaction and provide better commutation, thereby minimizing sparking at the brushes. Interpol windings contribute to a more uniform torque production and improved efficiency of the motor.
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.
What is the basic difference between carbon brush of AC slip ring motor and carbon brush of Direct current commutator motor?
The main difference is in how the carbon brushes are used. In an AC slip ring motor, the brushes transfer power to the rotor through slip rings, whereas in a DC commutator motor, the brushes switch the current direction on the rotating armature to maintain torque and rotation. Additionally, the design and composition of the brushes may vary to accommodate the specific requirements of each motor type.
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
Why are brushes staggered in dc motor?
To avoid sparking they need to be placed at zero point
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
