The link to that ADC 9.1 comes in at $1,923, maybe the price just jumped? but the wrap 9 is 1,680 and is rated at 28 hp for 1 hour at 89 volts that looks like the best option.
Well, for one downshifting is tricky without a clutch. But it does depend alot on your transmission and size of motor. Bigger motors have more armature mass, so clutchless upshifting is slower then with a smaller motor. And some trannies work better then others without a clutch.Whats the advantage for having a clutch? Im going to build a 63 bug. Im a new bee. Thanks.
I asked a similar question here http://www.diyelectriccar.com/forums/showthread.php?t=13630I'm trying to decide which motor to put in my 1991 Nissan NX1600.
The stock curb weight is 2350 Lbs. I'm planning to remove the clutch and connect the motor output shaft directly to the transmission.
ADC #203-06-4001 8" 72-144VDC 17.5HP Single Shaft - $1450.00
ADC #FB1-4001A 9.1" 72-144VDC 19HP Double Shaft - $1735.00
My needs are 15 miles range, 45MPH top speed.
Using a 120V pack, will I notice much performance difference? Will the larger motor have to work less and run cooler?
If there is not a huge performance difference, am I better off spending the $300 on a better controller?
It seems that "more is always better and too much is not enough" is the default answer.I asked a similar question here http://www.diyelectriccar.com/forums/showthread.php?t=13630
Never really got a suitable answer to it either.
Just a motor size change ? No controller , voltage , amperage or battery change ? Also check range , watt hrs or what ever info you can collect , before and after . I believe that a bigger motor will have some bad effects too at lower voltages . J.W.However.. I'm about to test something. Right now I have a 6.7" motor and it is not really giving me the power I want, so I'm about to upgrade to an 8" motor. We'll see if clutchless works as well.
