    I'm wondering how OEM VCUs communicate with their motor controllers and switch electronics during start-up of an EV. Besides the electrical start-up procedure with contactors and pre-charging, VCUs send a bunch of signals to the controller during the starting sequence (via CAN bus). Some of...

    I am working on a electric kart project. I'm slowly piecing together stuff. I'd like to use a Chargery BMS and contactor with a Alltrax SR controller. But struggling with the contactor coil wiring. The Alltrax seems to want everything to go through a footswitch to initially "turn on" the...

    Hi new to this forum so forgive me if I'm asking old questions. 1, what is the lowest voltage that the leaf motor works at? 2, Has anyone successfully used a Curtis controller on the Leaf motor? I'm not to bothered about running for a long distance, I just dont have much room for batteries.

    Hello, so after years of kicking around the idea I'm finally taking the plunge into converting my '72 Triumph Gt6 over to electric. I've managed to gain most of the basics from forums like this but I still had a couple questions. The motor im using to begin with is a 96v 200amp dc motor...

    Hello all, I'm looking to convert my 65' Corvair, but I'm having a hard time choosing between an AC or DC system. Does anyone have any "lessons learned" or "wish you would haves" using either of these systems?

    I'm on the brink of buying a 72v 7.5kW EV conversion kit from SHINEGLE New Energy Technologies Co., Ltd. I found it on Alibaba. I've been corresponding with the sales guy for over a month. And everything seems to be real. Before I take the final decision I thought I'd ask here to see if anyone...

    Hi all, When pressing the brake lever on my ebike the bldc motor controller (aka ebike controller) 'cuts power' to the motor until the brake lever is released again/sensor is deactivated. I would love to know how that works/what happens. I am wondering what causes the power to be 'cut...

    Is there any brain trust left on DCP Raptor 600 controllers? Mine is from a build done in 2007. It was an original DCP that was sent to Black Sheep Technologies for their wizardry. I have no idea what that means except that throttle changed from an inductive unit to a pot. All that was before I...

    My 10 year old Zilla based conversion is having a problem. The tach has been working for years, but recently the needle started to stick, then the Zilla starts to cut out. I figured out it was the Stall Detect and turned it off. That allowed me to continue to drive it, but not long after, the...

    Hey everyone, I've been working on my EV conversion, and if you want to see my current progress, here's a link to my latest video on it (https://youtu.be/V86oAZzfwRE). I'm working on wiring it all together and getting the motor to react to the throttle pedal. After trying for a bit, I came to...

    Hello everyone! I've found an industrial 15kW three-phase AC induction motor, and I'm in the market for a VFD to run this thing. It's a Baldor GDM2515T rated at 20HP, 230/460V, & 48/24A ("Full load amps"). It's weight is great for it's power and I like the fact that it's AC. I've found a...

    Hi folks. In this thread I'm going to present an all hardware DIY (Tesla) ACIM ASIC controller that does not need uC, DSP and programming. It is a spin-off of this thread about a similar controller for a DC series motor. Most of "can it be done?" stuff (simulations, breadboarding) is in the DC...
