I've been working with a senior design team this past year, we are developing a three wheel small solar car. See attached file for design.
Anyway, we purchased a LiFEPO4 24V,20Ah battery, developed a solar array, and found a converter able to charge the batteries. Here's where it gets hairy for us.
I purchased a 24V, 40A KBS kelly controller, and a 24V, 500W Conhis Front Wheel Hub motor. I went through all 36 connections, tested the hall sensors, check for shorts, checked conductance, checked voltages, current draw and double checked all the controller connections to no avail, the motor just would not spin. The motor would not even spin with a physical test, by just holding the mounts, it would grind against the casing. So...
I need help in determining a sufficient motor/controller combo for a 24V system. The battery's max current can go to 120A for 15secs, and we've tested it under different loading conditions, it works well.
I found a motor made by Golden Motors thats has a built in controller, that could be programmed for 24V. I would personally not buy a Cohnis again. Through all my tests I can't say that the problem is not with the controller, it has to be the motor.
Can anyone suggest a motor that we should purchase? Or does anyone have a suggestions of a motor/controller combo we should look into?
We need a motor that is rated above 250W and below 1KW
Thanks in advance
