First Induction conversion Done

[coldspot]

I've gotten my first conversion finished

Magnetek

Ser. 38DB 67318P

Mod. CA2D021N" 31-058327-03

115. V 60Hz
     
3. A 800/1550 RPM
   
   

.07HP A.O.

Class B INS MAX AMB 40`C

Thats All the Tag Info

I cut down the armature

Glued Neo grade 50 1/2"x1/16"

Two Deep by two wide, (length wise, going inline with arm)

Giving me 8 per pole, using 4 sets of this setup

Stock wires,. 4 coils of #22 & #27, (.025-.027 & .014)

I hooked up the stock three wires to a couple of

Bridge Rec.'s

(salvaged from computer power supply's)

And am waiting to test with a cordless drill

I don't have a half inch chuck one so I must

go to a friends shop to use his.

Cogging is a bit strong but, can still be turned with fingers.

This motor is a bushing not bearing so if it gives good output

I'll be searching for some bearings when I get some cash to play with

Local bearing shop should have something I could adapt to fit.

This motor also has three funky legs pointed towards shaft out end

and I might drill out the rear end and swap arm around to make better

use of these legs as a mounting system later if power is there.

test results posting later today.

tested with hand drill

Gen unloaded

400. RPM = 11.59VDC
     
1600. RPM = 49VDC
      
      

Update on magnets, after running out of first box

I opened an other box an this one has a N35 NOT N50.

Before I go much farther with these little

induction convesions-

Anybody have a plan to help me get up to

charging voltage with less RPM's??

Or should I just plan on unhooking the wires

and reconfiguring to a seperate coils state and

work from there?

I liked the 40+ volts DC but at 1600 RPM, I

dought I'll ever get a blade to spin it.

For testing this little gen conversion,

All I did was lathe down armature and add magnets,

then rectify the stock three wires.

Not sure if this counts for a 2 speed motor.

Is it 0.07 HP?

The 3 wires. Red, Black & White?

Try only red and white, with black disconnected.

Then only black and white, with red disconnected.

There are 2 sets of coils. Red set and black set.

The white goes to both sets.

Rectifing it as a 3-ph, not sure what would happen, but I would expect some kind of troubles.

If that helps, follow the white wire to its end, cut one of the 2 coil wires, add a blue wire to the one just cut.  Makes 4 wires and 2 single phases. Put a bridge on each pair, parallel the bridge outputs to the battery.

THANKS ghurd-

I'll look into that

Yes it's a 0.07HP

The rotor will fit into a boxfan one

(was a bit wider but smaller around for easy mag placement)

Also, on a different one-

"AOSmith electric motor"

Mod 324P122

HP 1/4, Rot REV,  Ser 3E88

RPM 1075,   Type FLL

Volts 208-230,   PH 1

Amps  1.5(1.9 Max),   Hz 60

INS    B*  AMB 60`C   Air Over Duty

Code   E46993

Thermally Protected

MFD 5/370V         LR 5072

FS1026S

  Thats ALL tag info

With this

Connection Diagram-

Brown

Brown/w

These to "SEP.CAP."

Yellow

Black

These to "Line"

Also smaller black n white, (two sets each)

to a reverisble plug for rotation  

This motor has 6 coils in two seperate sets

inner and outer sets

All are of # 22 wire size, (0.025)

36 slots

This conversion has been done for a few weeks,

(magnets glued to turned down rotor, two deep

two wide and two tall, for a total of eight per pole

4 poles) This fills coil center.  

Have a few more mini bridge's out of old computer

power supplies, (most of these tend to be a 600V-800V

4 Amp)

(Did find one 5 leg unit that the AllDataSheet

stated was a 500V, 5 Amp Voltage Doubler, need to figure this one out)

Anyway, any thoughts on this one's wires?

PS: have a Great Day

[ghurd]

Sould be the same???

Best guess...

The yellow and black line wires are the same as black and white?

One of the browns is same as the red?

The other brown is just connected to the yellow inside the motor?

The 0.07 motor should make a dandy (low efficiency) trickle charger with a fan blade, but will take some trial and error before a good blade is found.

Look for a wide slow blade, like a 20" box fan. Expect 12V cut in in a very slow wind.

Thanks ghurd

someday

I'll finish the boxfan one

I don't like the wire size and have salvaged

some # 18 to use in it.

Also your 4 instead of 6 magnets seems to help the

conversions turn better.
