Excessive sparking at the brushes in a DC motor can be caused by several factors, including improper alignment of the brushes, worn or damaged brushes, and uneven commutator surfaces. Additionally, excessive load on the motor, incorrect brush material, or insufficient brush pressure can also lead to increased sparking. In some cases, electrical issues such as arcing due to high voltage or a short circuit can exacerbate the problem. Addressing these issues typically involves inspecting and maintaining the brushes and commutator.
the reason for brushes is to makethe motor revolve. The more brushes probably make a more powerful starter motor
"Induction" motors imply AC power Most AC motors do not have brushes or commutator If your motor does have brushes, a lot of sparking where the brushes meet the comutator is a good indication that it needs to be cleaned and/or "cutdown". If your motor does not have brushes, then you have more serious trouble. Need more details
yes
There no brushes in an induction motor. The rotor is independent and is a short-circuited cage of parallel bars.
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.
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.
the brushes in the motor are worn. If you are handy, some auto parts stores sell brushes that will fit the motor. You may have to grind them down just a bit to get them to fit, as well as solder the wires in place. A new motor was $130 for my 2001 Chryslet Town and country. I had an old drill I sacrificed and removed the brushes and did it for the cost of an obsolete drill.

They work independent of each other in this situation. Your blower motor may be worn,(brushes worn). I would take a test light to the hot lead at the fan motor to see if there is power to it ;if there is, that tells you the motor is shot.Get yourself a new blower motor if that is the case.
The blower motor is beginning to fail. Bearings, bushings, or brushes are probably worn.
In a 1997 Toyota Prado starter, the brushes are located inside the starter motor assembly, specifically within the starter's end housing. To access them, you typically need to remove the starter from the vehicle and disassemble it by removing the end cover. The brushes make contact with the armature and are crucial for the motor's operation. If they are worn out, they can cause starting issues and may need replacement.
Motor brushes ride one the commutator.
Carbon
The normal number of brushes is 2.

Carbon is much stronger and because the motor commuter is spinning copper brushes will wear off quickly.
