Hi Wood,Is that 5min rating going to matter much?
That is a fairly common bar count for these fork motors of that size.i have another GE 11.5" 15.5" long motor, and it has 65 comm bars! isnt that alot???
Hard to say.does this mean i can feed it high voltage like 200v?
Difference between pump and traction motor design.the odd thing is though that the 8.5" motor has huge brushes for its size, and the 11.5" acctually has its brushes a little smaller...
I can't list everything for you here. Read thru http://www.diyelectriccar.com/forums/showthread.php/using-forklift-motor-and-choosing-good-7598.html Like I told woodsmith, it looks like a good well built motor in decent shape. Whether it is right for your intended application is a different question. And I usually don't answer that particular question. Too many variables. You do best by reviewing what has worked for others with similar applications as yours.so what are the basic reasons why that motor would be good major?
Hi Dunc,Hi Guys
Voltages in series DC motors
- the way I understand it 10 - 20 volts will drive 1000amps through one of these
But you need your 10 - 20 v + the back EMF caused by the motor spinning
So for a given speed and current the motor voltage is going to be Back EMF + 10-20
If you don't increase the speed you can't increase the motor voltage
Therefore your battery voltage is irrelevant - except that a higher voltage will result in a lower battery current
Therefore you should use the highest voltage your controller can handle
Brush advance is also related to speed so the same thing
Have I got this right Major?
