In this way to make a alternator as AC Motor is needed. Generally AC Motors are classified into two main categories. They are,
Now we are going to just replace rotor with permanent magnet bars. In this case we need some permanat magnet ( Bar Magnet). The size of the magnet should be same as the already replaced rotor.
Permanent Magnet:
The permanent magnet used to make a alternator should be strong. So that it have a strong magnetis field to produce more electron flow in the coil. The permanent magnet can be neodymium type of magnet.
Number Of Magnets to be used:
To determine the number of magnet to be used can be calculated by the total number of coils. For Example,
In the rotor remote the shaft alone. Then a cylindrical wooden piece and put an hole in center of it. Fix the shaft into that hole. Around the cylindrical wooden piece fix the required number of magnets on it by using resins. After pasting all the magnets leave it for sometime. Make sure that the fixed magnet should be separated with non magnetic materials.
Now check the connections of the coils in the field(stator). If all the coils in the stator is connected series, then will produce high voltage and low current. If the coil is connected parallel, then it will produce low voltage and high current. After checking and making the connections correcting, replace the newly made rotor into the motor. Now the motor becomes permanent magnet alternator.
Working:
When the shaft is rotated, the magnetic field produced by the permanent magnet is induced in the stator core and there by create a magnetic flux. The flux will makes the electron flow in the coil. Hence there is a current flow and the output voltage can be measured by using a voltmeter.

To determine the number of magnet to be used can be calculated by the total number of coils. For Example,
- 2 Coils = 4 Magnets
- 4 Coils = 6 Magnets
