What generates more noise ac motor or dc motor?
dc motors generate more noise.
There are two methods of doing it Ac motor to DC generator coupling Rectifiers You couple the axis of a AC motor with the axis of DC generator. So the AC motor generates torque and rotates the axis of DC generator which generates DC power. The other method is use of rectifiers. There are two types of rectifiers half wave and full wave. Full wave rectifiers are more effecient but you cant control the output…
Why is your car making a grinding noise when you have the AC or heat on and you brake to slow the car and or give it gas?
It depends on the construction of the motor. If the field winding is connected in series with the armaturewinding, the motor is like a universal motor and will probably operate normally. If the field winding is connected in parallel with the armature, the motor will not run, but will draw current, make noise and get hot.

Look at your AC pump, and start your motor and turn on your AC. Listen for the clicking coming from the pump. That is you clutch cycling on and off for the AC. If that is the noise you are hearing then your good to go. If not then you will have to look else where, BUT BE CAREFUL when the engine is running.
if you power an ac motor with dc or a dc motor with ac you will likely start smelling smoke and the motor will be damaged. If the motor is marked "3-phase", "shaded pole", or "induction" it is an ac motor! BTW, there are ac/dc motors that will run on both, they are wound very much like dc motors but a bit differently.
