What are the materials used to make brushes in Electrical Generator?
Carbon, due to it's high melting point.
In a DC generator if the brushes are given a small amount of forward shift the effect of armature is?
is fully diamagnetise
In a dc generator brushes are placed in which side to avoid armature reaction?
along the M.N.A axis along the M.N.A axis
Name the essential parts of the motor and generator?
Engine Alternator Cooling and exhaust systems fuel tank voltage regulator control panel
What is the probable cause for no voltage generated in a DC compound generator?
In any DC generator the causes to fail to produce voltage is loss of residual flux in the field or fields , poor brush contact in the commutator(clean the brushes and commutator) , check all the terminals of the generator and voltmeter may not be functioningand lastly check the coupling and the prime mover is rotating.
How do you change the brushes on a 1971 vw camper?
By brushes, do you refer to the windshield wiper motor brushes, or the generator brushes? If generator...just replace the generator, or ramp up to an alternator. It is cheaper and a lot less hassle. If windshield wiper...well...that one is possible, but dreadfully difficult. Best to look for a replacement motor. I don't think they make the replacement brushes any longer.
Why is the generator light on in your 1971 type II VW bus?
your generator isn't charging. try replacing the brushes. if not then try thesamba.com and look for another generator.
Short note on metadyne and amplidyne?
an amplidyne is usually an ac motor driving a dc generator with modifications to increase the power gain available. a small electrical signal can control the position of a large motor using this approach. an amplidyne is a special type of motor-generator, which uses regeneration to increase its gain. energy comes from the motor, and the power output is controlled by changing the field current of the generator. in a typical generator, the load brushes are positioned perpendicular to the magnetic field flux. to convert a generator to an amplidyne, we need to connect, what would be the load brushes together and take the output from another set of brushes that are parallel with the field. the perpendicular brushes are now called the quadrature brushes. this simple change can increase the gain by a factor of 10000 or more.
How does the generator terminal voltage rise and the motor speed fall when the brushes are given a backward shift in a generator or forward shift in a motor?
A generator is a back up of power. A generator can only give so much voltage.
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 are the materials used to make brushes in Electrical Generator?

In a DC generator if the brushes are given a small amount of forward shift the effect of armature is?
is fully diamagnetise
What is brushes and bearings?
Brushes and bearings are component parts of a generator. The brushes are used to deliver the field voltage to the revolving rotor. The bearings are needed to allow the rotor to revolve. The bearings also maintain alignment to prevent the rotor from dragging on the stator.
Why is brushes placed at MNA in a dc generator?
to avoid sparking ,since their is no e.m.f induced in magnetic neutral axis.
Why is my Yamaha 1980 650 special not charging the battery?
probably worn brushes in the generator, ez to replace about 15.00$
In a dc generator brushes are placed in which side to avoid armature reaction?
along the M.N.A axis along the M.N.A axis
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.
