Hello, am looking for a motor that can carry 500lbs go kart on grass/muddy with 10incli uphill, speed around 20mph. I was thinking about putting the 1000w in parallel and would use either 1 or 2 controllers with reverse. Would that work?
If that would work I would also need brakes and sprocket for 3/4 shaft and keys also
Hello again...i know you guys are doing your best to answer all questions and sometimes its also difficult but am completly lost with the torque and weight thing. If the above is possible without stressing the motor too much I would like to buy it and other parts that I need.
In your previous reply you mentioned 8mm how about #35?
Two 1000 Watt motors should be able to handle the gear ratio shown above with a 500 pound kart in grassy/muddy conditions and 10 degree inclines. Our grade power calculator shows that the two 1000 Watt motors would slow down to around 11 MPH when going up a 10 degree incline which is within specifications for the motors as they would be running at 1600 RPM at this speed so they would not be lugging. Here is the calculation.
I know that #35 axle sprockets and adapters are easy to find for go karts so it would be a good size to use. Although we cannot get #35 sprockets for our motors, our 1000 Watt motors do have 12mm shafts which a #35 sprocket with a smaller bore could be drilled out to so it fits the motor. We carry a 10 tooth #35 sprocket with a 3/8" bore that could be drilled out to 12mm to fit the motor.

As far as controllers and reverse relays go two 1000 Watt controllers and two reverse relays could be used with the two motors. We could make a kit out of all these parts that had one power switch and one reverse switch to control everything.
We still need to figure out runtime and the battery pack size. Our 1000 Watt motors are available in 36 and 48 Volt versions. There is no difference in power between the versions the only difference would be the number of batteries in the battery pack. Here are some calculations showing the 36 Volt battery pack sizes needed for certain ride times. These calculations are based on full throttle riding conditions with some hills. If the go-kart was used on flat ground or at less than full throttle some of the time then the ride times would be longer than these estimates. Here they are.
Are you leaning more towards a three battery 36 Volt system or a four battery 48 Volt system?
How many minutes of runtime do you want the go-kart to have on a single charge?
thanks again for the reply. Can you make a kit please? for the battery i am probably going with 36v 35Ah but i havent decided yet.
i am going with one motor actually since its going to be offroad on uneven terrain which might be a problem with 2 parallel motor..
Please have a look at this kit and let us know what you think. We can make any changes that you would like to the kit such as different size batteries, different throttle, remove the Voltmeter, etc.
Please let us know if you have any questions.
