Mods, please move if there is a better spot.

My team builds prototype machines...this particular application is giving me a headache. Any help would be GREATLY appreciated!

Looking for:

Variable Speed Electric Motor and Controller
24V
Minimum 3.5 kW (~5 hp)
Must be able to go up to 2000 rpm (would prefer maximum rpm of 3500-4000)

That's a pretty tough spec which is probably why it's giving you a headache. Usually for something like that, you like higher voltage like 240v because those motors last longer than 120v. Let us know if you find it.

Try looking at military surplus motors that run hydraulics or other associated devices.

5HP from 24V is crazy. 3.6KW at 24V is like 150 amps. That's starter motor territory.

There are many in off-highway equipment...the tricky part is the "variable" part.
Can you drive ANY 24V DC motor as variable with a PWM? I have one in hand that is being driven on/off, but I don't know if I can drive it variably.

I am also looking into golf cart motors...many of them are much more powerful than I need...but start at 36V-48V
If I have a 48V golf cart motor, can I drive it with a variable 24V source? I've found a variable golf cart motor that is rated for 10hp at 48V - can I expect to get 5hp driving it at 24V? My simple DC equations I do remember tell me I can...?

Out of all the classes from engineering school, this is the one I remember the least about.

The tech exists for home HVAC - PSC/ECM motors work on that same principle but using AC and at line voltage. Almost like the motors inside of a Prius.

All the stuff I'm seeing via Google are 48V DC motors from China that can put out that power. What the heck are you building?

Yes you can drive any brush-type motor with PWM to slow it down. The PWM controller is a generic item you'd select based on volts and amps.

Running a motor on less than rated voltage the hp is likely to drop by at least voltage squared, i.e. 1/4 the power for 1/2 the voltage.

Sadly I can't share that right now.

If it’s something classified or proprietary, you presumably have better resources at your disposal than BITOG... right?

Another idea would be using a DC controller to control an AC motor, which are much more plentiful.

you will want a GM BAS+ (eAssist) Motor Generator from one of those mild hybrid

it's 20HP 44ft lb torque it will need to be water cooled though

36 volts

With that much information given its pretty hard to find anything that would be remotely helpful to you.

I do...but I have been surprised at some of the knowledge on this forum. It often surpasses some of the "experts" I interact with.
