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.

The part of the armature that the brushes ride on is called the?
Motor brushes ride one the commutator.
Why are the brushes of a dc machine always placed at the neutral points?
The function of brush is to collect current from rotating commutator and supplies the current to external stationary load. The brushes of a DC machine are placed at neutral points because the current in the rotating part drops to zero at the neutral point. If brushes are placed in location other than the neutral points, then the current may be switched off and it causes magnetic field and it may also create voltage spikes and arc at brushes.
Why carbon brushes are used in DC machines?
Carbon brushes used in DC machines because carbon is soft material and it does not generate spikes when contact with commutator
Do generators have brushes?
Most do, but not all. Some have a separate exciter winding.
What is staggering of brushes in dc machines?
Staggering of brushes is nothing but displaying the positive brush sets in one direction and negative brush sets in the other direction. This ensures uniform wearing of commutator segments or surface (and avoids steps like between brush sets).
What are the components in an alternator?
Stator, armature, rectifier, bearings, brushes,
What is brushed bearing?
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.
Can sand wreck an alternator?
certainly, sand is very abrasive and can ruin the bearings, windings, and brushes.
How do you replace the starter motor brushes in a 1997 Toyota Camry v6 conquest xv20 series?
Its not worth replacing the starter motor brushes on any car. By the time the brushes are worn, there is probably other wear and tear to the bearings, the commutator, and the windings. Better to just replace the starter. Same deal with the brushes in an alternator.
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 is the main part of ac motor?
shaft, windings, ball bearings, armature, stator, commutator, brushes, terminals, case.
What can you do if a 1996 Jeep Cherokee AC blows cold air but the pressure of the air is not constant?
The blower motor is beginning to fail. Bearings, bushings, or brushes are probably worn.
What are the parts and its function of electric motor?
1. Armature coil 2. Field magnets 3. Split or Slip rings 4. Carbon or metallic brushes
What are the possible losses for a dc generator?
Friction in the bearings and in the commutator, and windage loss. Electrical resistance of the armature and field windings and the brushes.
What are the signs of a alternator going bad in a 1997 Mazda Protege 1.8?
alternators go 'bad' in various ways; bearings = noise diodes = no charge, insufficient charge or discharge. brushes = no charge
I have a western uni mount snowplow and it raises slow and dims all lights?
check the brushes and bearings in your motor make sure you have a good ground and the connections are clean but most likely the motor is shot
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.
