Default 60 HP ...830lbs AC Motor...will it work???

I am considering a baldor premium efficient 60 hp electric motor a friend has access to...but it weighs 830lbs! here are the basic specs:

60HP
230/460 V
FL Amps 135/67.8

My question is, if I put this into an old FJ-40 w/ a 4 speed manual transmission and 4 wheel drive (similar to a jeep body style)...w/ a curb weight 3200 lbs (4000lbs w/ the motor), will it have enough power to handle the hilly terrain i live in and modest highway speeds? how will it be on batteries?

please give me some feedback if this is a good motor for my project...THANKS IN ADVANCE!!

You would need a sh** load of batteries prob.. 15K plus dollars..

Check out this truck and motor, I went for a ride in this truck
and it runs like it has a v8 in it.

This is the link for the full size pickup..

I am building, rewinding a baldor for my truck. Want a
little bit bigger than a ac50 motor..

i checked it out! thanks...actually, i saw another post somewhere that you referred to it and i looked it up earlier ...but, that motor is 50 HP (ok, close enough) but it has 362 amps and 72 Volts, so I don't know how those differences will compare to my motor (not to mention mine weighs 340 lbs more!!!) ...so what will happen in my case with those differences????

What does " a friend has access too" exactly mean? Are you buying it? if so how much? is it free?

If its free I would take it and sell it and use the money to get another motor that is better suited for an EV.

As others have said you still need to take into account the 5-800lbs of lithium you will need...

He has a new $7,500 (retail) high efficiency motor that he can sell me for $2000

This vehicle you shared would still weigh more than mine even with my motor weighing in at 350 lbs more. Would mine draw a lot more current? Be less powerful up hills? What exactly would be the problem with this motor other than added weight?

well find out how much you can make by selling it for him, be a good friend, and split the profits, and use your share to buy EV parts, not industrial parts.

My goal is to find something that will work on the cheap. Even if i tried to resell etc, i am going to fork over much more cash to buy something ideal. I'm wondering if this motor could still manage hilly terrain, highway speeds with reasonable battery usage.

Otherwise i agree. (but my pocketbook doesn't)

Ok going to try and keep this basic. You really need to figure out what voltage you are going to run (motor and controller) The higher the voltage the more batteries you will need, and lith. batts. are not cheap... So with that in mind, that is why i choose to go with the Curtis 1238 controller.. I am only gone to run 30-32 200amp hour lith batts.. You allso need to look at motors, not just the hp and amp, but the continuous rating. Like Kevins motor is 50hp CONTINUOUS unlike the ac50 says 67-70 hp, sounds good, but it is only 20hp continuous.. Big difference.. I was originaly planning on using the ac50, but i live in Tucson AZ, it is 108 today, I feel that motor would not push my extended, loaded 1999 sonoma pickup. I am buildin a little bigger motor and building a water jacket for the housing. So since i am using the 1238 curtis controller with a output 70 rms volts, I need to rewind the motor for 70 volts..I hope this helps a bit more.

Just installed the trans and motor in the truck today. Need to build the water housing and rewind stator..

My extended van uses a 30 HP 3 phase induction motor, hooked right to the driveshaft. No problems.

Yes you need 600 volts DC or more to operate the required industrial inverter.

The motor you mention would certainly work, but it is quite heavy. I'd say no more than 30 HP induction motor is actually required.

the 60 HP motor you mention with a 300 kW inverter would be a great performer though
