Your belt going to the alternator is probably very loose and the motion of the turning alternator is continuing after you turn off the vehicle. Get the belt tightened right away.
The theory to " spin" the alternator is the same as spinning an air compressor. The ac motor, whether a single plase or industrial three phase motor, to turn the belt or chain driven item,alternator or air compressor pump. the schematic for an air compressor would give you this answer for the a.c.app.
the motor is 2
It causes the motor to spin.
if it doesn't spin at all, yes it is broken if it doesn't spin at all, yes it is broken
the starter
they spin when the motor reach a temperature, ussualy is on a 1/4 of temperature
In order for an electric motor to spin freely you will have to make sure you have one thing. You have to have the electric current for the motor to run freely.
The bearings on the alternator could be going bad. Remove the belt from the alternator then spin the alternator by hand to listen for grinding.
A 60Hz synchronous motor spins at synchronous speed - if it's a two pole motor it will spin at exactly 1800 rpms. An asynchronous motor will spin at a speed lower than the power supply frequency - a symilar asynchronous motor may spin at 1700 rpms.
depends on the applied load
When the batter supplies 12volts of electricity to thw atarting motor and the motor then bwgins to spin which eventually activate the alternator and other appliance on the engine all of this is mechanical so then the alternator will convert this energy when its shaft spins into electrical engery thus supplying energy to other parts of the vehicle. I'm a current student in automotive so if there is any problem with my answer please help I would be very greateful
Clockwise.
