I work on a farm and our gas powerd ATV's are high in maintenance.
I thought it would be a good idea to convert one of our old suzuki ozark into a all electric vehicle.
I was thinking of using a me1003 motor, directly connected to the differential drive line. (I already have the motor so it makes sense to use it) a alltrax SR-48400 controller and a 10s2p nissan leaf battery pack( 36v 120amp )
So my question for all the experts out there is, would i need a transmission or gear reducer? Would my set up produce enough torque to "get up and go"(top speed it's a issues. 10mph is perfectly fine)
It's also worth noting that the differential is a 3:1 ratio and it has 22" tires. And we only need about 2hrs of of battery charge. It will be charged at lunch and at the end of each day.
Thanks for your help and advice!
Howdy & welcome,
You say, "I was thinking of using a me1003 motor, directly connected to the differential drive line."
...directly connected to the differential drive line?
What do you mean?
...with a chain?
3:1 ratio is a bit stiff & 22" tires have a lot of rolling resistance
...but, 10 mph should be doable
I put a motor like that on a Dingo go cart with bigger tires, a few years back
I ran it @ 36V also, it moved right along
the biggest drawback was the weight of the batteries
...I used (3) 12V 35AH SLA batteries (~20 lbs. ea.)
...it was so heavy In the back that the steering was more like a suggestion than a command
That motor, controller & battery pack is now on El Moto my electric motorcycle conversion
...a much better combination IMHO
When I ran it
[email protected] 36V the top speed was ~25mph
...now @ 48V, top speed seems to be ~35 mph
It has a 5.4:1 ratio (10 tooth drive gear & a 54 tooth driven gear)
