Brushes rub against rotor and, functioning as electrical connections, they usually make sparks. So, they unavoidably wear out.

Why do door motors get burned?

All motors are made up of 2 basic parts, a coil or coils of wire, and two or more magnets. the motors found in cars and car windows contain dc motors that use a pair of brushes to make contact with the coils that in turn drive the magnet. as u continually use the motor, the brushes are worn away due to friction, once the brushs no longer make contact with the commutator (the copper plates where the brushes come in contact with the coils) the door motor with stop working as no current is able to pass through the motor. you either have to get the brushes replaced, or replace the motor entirely

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.

1999 Grand Cherokee turning on the fan control has stopped working but comes on for short periods sometime?

There are a few problems for your symptom. One problem that happens to the Automatic Zone Control (AZC) systems is the blower motor connector that connects to the control module, it overheats. Mopar has a connector harness repair for this problem. The blower motor resistor and the blower motor controller are a couple more problems that could occur. Of course it could be the blow motor itself, along with many more things. If you are going to do the repair yourself, you should start by purchasing a repair manual and following the blow motor diagnosing procedure.
