2pole 20hp and My 10 hp motor water jacket
« on: April 20, 2014, 01:59:34 PM »
 :Up>:

I have been winding the 2 pole 20 hp (winding it 4 pole) motor and my 10 hp with the water jacket.

This  2 pole 20 HP has a lot of back iron a smaller stator and rotor (length wise).
wound it  36 slots 3 coils per-pole (big slots ) at 16 inhand 18 gauge two turns. (each phase was 55 feet of wire)

My motor 36 slots  3 coils per pole the 10 HP is 12 inhand two turns.
(I just hope I can beat the torque of the ac-50, or I won't be happy :O):)

Miz and I are going to compare his 20 HP and this new 20 HP motor on the dyno.

Here is a video on doing the connections. ..   :mE>:

Got the winding done on the 20hp,  did 2/0 leads coming out of the motor, BIG connections.  :Ah#:
2/0 welding cable and 32 18gauge wires for each delta connection, luckily had lots of head room in this motor.

 :sf<:
Now just pour varnish and bake in the BBQ.

That is pretty! Have you covered the varnish and bake? I know you covered the burn out and such.

The BBQ has a cover, bake at 325-350F for two hours, only put the cover on a burn out because it is standing on end it keeps the heat in.

             Ok, got both motors wound and back together, leads on and ready to run on the Dyno.

    Just need to get together with Miz   :Ll>:   to gather the numbers on the dyno.

 :<bs:  Well a thought I would put my ten hp motor (water jacket) on the dyno today,
and to my surprise it is doing twice what the ac-50 will do on torque.

225 foot lbs of torque out of a 10hp motor

It is finally going into my truck.  :>ba:

I don't have the computer connected to the controller but thought I would post a small video running my 10HP water jacket motor on the dyno. I am getting twice the torque of the ac-50.

Twice the torque, but out to what rpm?

About 5600 RPM  225 foot lbs torque  the motor has hit 6000 rpm.   :el>:

Congratulations on the good results, at what voltage were these numbers taken?
Looking forward to the results from Miz's motor.

We are winding for  ONLY the curtis controllers.

What voltage?  the controller in a 1238-8501  96volt the motors a wound for (around 50-60 volts)

 :Up>:

Got some new numbers (locked rotor torque) locked down the rotor and full throttle.

After running the optimization on my 10hp motor yesterday the controller set the slip gain
at 5.90 then I did the locked rotor test and got 65 foot lbs of torque.

I changed the slip to different numbers,  set it at 3.30 and was able to get 107 foot lbs of torque.

I am pretty impressed.

Edit::  I did not have the amps maxed out changed controller setting and I am getting 225 foot lbs of torque (locked rotor)

What I ment was, what's the voltage that fas fed to the controller?
Impressive results, I hope all the rewindings of this motor have finally paid off :D

I have  16  6 volt batteries feeding the controller. right about 100 volts..
