Not a induction motor. This is a series wound motor. It could have been simply rewired for reverse by reversing the field wiring with the commutator ( brushes).
you do know that when you put a load on the alternator it takes horse power to spin it,,,you sure that little PVC pipe pulse motor is going to spin it??? NOT!
PART 1_ Well you don't really need to use magnets... Just let some current flow through the rotor thus making it a magnet (more current=more magnetic flux), then spin it mechanically and take the output of the Stator fields.
PART 2_ Or you can do the opposite... apply current to the stator making IT a magnet then spin the rotor mechanically then you have the output of the rotor's cabling. Perm magnets are made using energy anyway... wanna help, although i don't believe in free energy the way you mean it... i believe in renewable sources and better efficiency.
Hi i took an old induction motor and drilled 4 small magnets 10mm north south into the shaft did not uncoil it and got 13volts the amps "if i tryed to pull amps from it just slowed it down" but got 600mil amps of it
Don't waste the prefab shaft... Just use the stator and spin a new shaft with 4+ magnets on it. If you really want to get crazy spin the magnets outside the stator coils, as the further from the axis the faster the relative speed per rpm.
you probably got help already but here is my two cents. I wouldn't tear up a good motor. different shaft would be the direction i would go. but if just chef not engineer or english teacher. ha
you could even get some steel rod the same diameter of the one from the motor and other parts to make a blank shaft. then add the magnets, start with only 2 magnets that way you wont have a huge magnetic field to overcome when you hook it up. if you find out that you have enouph torque than bump it up too 4 magnets. get magnets that are the same length as the inside of the coil housing.
Agree with REG45401; Get steel rod (Home Depot) with same diameter as this rotor. Cut shaft to length, then buy two or four neodymium magnets (ebay) to fix to the shaft. You can also get ferrite field magnets from discarded PM motor. Place the bearings on new shaft (sanding may be required). If you need 60Hz output here's simple formula: 7200 / number of poles = rpm required (also 7200 / rpm = number of poles required). There will be some cog, but once it's rotating won't be too bad. Good luck..
Hmmm. . .well I am looking at trying to make something like this and was looking forward to reading all the comments you got . . .but now i done that im still non the wiser as some say remove some say dont so many different answers. So im no further forward just 10 mins life down lol hope you decide which answer is right or better. Many Thanks keep it up
Im gona say get the magnets out of a 12v drill that has perm mags,and make a roter,just set the roter that was in the moter a side,numan moter ,window moter ,theese work well.can be made brushless,
an relay can be made to + - power,brushess can handel more power...you need to add a set oof winds to get more back emf ...
You need to try your axial flux alternator again...
It is best for low speed apps...
Go to Otherpower dot com and they can tell you everything you need to know about all kinds of stuff...including how to convert your motor you have there to an alternator.
BTW I am building a 3kw Axial flux and plan to drive it with a pulse motor using the bifilar coils...
The Axial Flux Alternator is best suited for the low speed app.
I am using #14 wire with 3/4x1.5x3 neo's for the 48volt system.
Way to heavy! Wrong dimensions. We took shopping cart wheels, and kids plastic bike wheels & directly screwed in ring Neobium magnets. Place coil about 1/2" outside magnet ring. This way the magnets serve as a fly-wheel as they get reversed polarity from the coil through either a power transistor or 555 timer. See Nastrand 2000, also Robicop for working examples.
Just hook up the stator and rotor to separate power supplies and it'll spin in both directions if you reverse one of the supplies, or replace the stator windigs with permanent magnets.
just get an old magnet generator out of an old tractor-they already have permanent magnets on the rotor.Also the old wind up telephone generator,and dynamite blasting plunger box.
befor jumping onto this big motor, could you try something? Pulse a 9 volt(reed and darlington transistor) to a small dc motor. when its on you use power when its off you generate power. with the rite gearing of dc motor and weight (for centrificul force) the motor runs for free. Days of a turning wheel/fan/whatever with a regular 99cent 9volt.
Pulling the center of this motor and replace it with some neodymium magnets, preferably wide magnets that will replace the width of the coil on the axle. You can than turn your shaft into a commutator on the outside, and take the coil wires hooked up in series, than take one side coil to positive battery, and another side of coil to the shaft or bearings. Than take negative side of battery and time this on the commutator half firing. Than reverse coil sides with another battery same time.
have you thought about putting the magnets on the stator part and using the armature for the inductance then it should run like your typical little d/c motor like wise should produce electric current when cranked over the problem is that when the leads are put on a load it will cause friction and heat on the armature the method that you were told before will produce the same affect though with the friction that is try a battery powered drill motor assembly with the gear reduction system
I am pulling apart a motor just like that from a mixer. Getting all that copper out without messing up the rest of it will be a pain. All that glue holding the wireing down is giving me fits. All I want is the commutator and the shaft so I'm going to cut the rest off with a dremel tool cutting wheel. Hopefully I can to it without destroying the shaft. Good luck.
don't cut the wires on the rotor

Your better off just finding a pm generator. If you do all that it might not be efficient .

I agree, the windings on the rotor have to go...
unless you want to convert to slip rings instead
of a commutator and make those center poles electromagnets :D
Provided you can properly separate the windings.
