Re: Goldenmotor VEC500. Insides + mod help

Actually these fans are with ball bearings and I think they will last long enough. I''m not driving every day. One-two day a week max and then like 3h max.

Re: Goldenmotor VEC500. Insides + mod help

Hey I think the controller is universal, they just preprogram the values and sell it as separate models 48, 72, 96 in case you do not buy the programming cable. But are you sure that 48V motor can handle 72V. In my knowledge it is 100kv motor and max rpm is 6000. So 6000rpm / 100kv = 60V. In that ca...

Hey Do you know how well the cooling is done? I have the same VEC500 and it seems it overheated with constant 200A current. It blinked led 14 times and I could drive if it cooled off. And My plan is to install 5cm thick aluminium radiator with fins behind it 20x20cm. And then cool it with fans. But ...
