We have completely de-ICEed the car. Also we recently acquired three electric forklift motors, amp
le (ha) power cabling, and a control system from an old forklift for FREE!
We're gearing up to start adapting the drive motor of the forklift (other two are hydraulics) to the transmission and machining the coupler.
Additionally, due to monetary/time reasons, we have downgraded our expectations. New requirements: 30-35 mph, 12 mile range.
We'd like to use some used golf cart batteries at a low cost and I hope this will get us to our goals. However, I still have a few concerns - the motor is only rated to 24v and is 7" in diameter. It is an extremely light car, but I hope the motor will be enough. It was hard to beat the price...
I've seen 24v motors used in a few conversions, how safe is it to overvolt them? And thoughts on voltage or other battery pack specs (lead acid for cost) for the aforementioned goals? Also, is there anything we need to do before we bolt together the motor and tranny to still use the OEM spedomoter and tachometer?
Keep in mind we are high school kids with small albeit expendable incomes from summer jobs - we are trying to do a "rat rod" conversion that will get us to school and back.
We also decided to go clutchless in the interest of time and money - I can already shift (up and down) comfortably in an ICE car without the clutch.
Thanks! Any advice/comments/critiques are much appreciated!
Also, here are some pics!
