Hello - Glad to find this forum!

I helped to build an EV back in 1996 using a Saturn and Nickel–metal hydride batteries.

Fast forward to 2020 - I bought my first EV for $500. A 1970 VW bug with a Hyper 9 DC Brush Motor, Curtis Controller, and 32 LiFePO4 cells.

The batteries were shot so I am going to use Tesla cells with the same motor/controller.

Welcome, Woody!

That would presumably be a WarP 9 brushed DC series-wound motor, since the HyPer 9 is a new permanent magnet AC synchronous motor.

Im thinking that maybe the 9" motors were called Hyper 9 in the early days of Warfield Motors. I'll ask them.

Thanks Brian! Yes you are likely correct. Actually I know I am wrong. I know its an Impulse DC due to the sticker on it. From what I have read it was a popular motor choice for a while. I am hoping that I will be happy with the results once I get the Tesla modules.
