  1. Electric Motors
    hi all noob here I am converting a Nissan Z31 to electric, and I am using a design that utilizes 2 brushless motors connected to each other in series to drive the transmission shaft through the stock powertrain. I was originally going to use controllers that had a feature that synced the 2...
  2. Electric Bikes
    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...

    I've been riding motos since i was 10 and I love to wheelie and was wondering if how much power must a motor produce to wheelie? (relatively low speed start) I'm starting with a supermoto setup that was about 260lbs before removing ice junk, large sticky tires on pavement for good grip. I have...
  4. All EV Conversions and Builds
    Hello, i am considering starting an EV conversion project for the taxi vehicles in my city and would like to know if this is at all doable. The proposed donor cars weigh from 1000 kg to 1500 kg (without passengers). The cars in question are WV Passat, WV Golf 3 and 4, Reno Megane, Opel Astra...

    Hey everyone, I'm currently an EE student and part of a SAE Supermileage team. I've been researching motors over the past week or so. Our team needs two new motors to drive our electric car. We currently have a set-up of 24V system, and about a 3200rpm gearbox. We're looking for a motor that...
  6. Technical Discussion
    Hi everyone, We recently got hold of a nice HVH250 (without the casing, and that's a PITA, but it's another story...) and we're planning to power it with a nice 400V/400A controller. Except... that the controller only accepts hall-sensors and not cos/sine resolvers like the one that is mounted...

    Hi everyone, I've been lurking here for the better part of 2 or 3 years and want to integrate into the community a little bit more. I'm not as much of an expert as I'd like to be but I've got project ideas that could use a few tips. I like brush-less motors and am reasonably familiar with 3...

    I have for sale a slightly used BLDC controller with a program interface. I've built my EV with GoldenMotor BLDC 10kW motor. The motor appears to be not powerful enough for my can so I've decided to switch to ACIM system. The motor is already sold but I stile have a controller and a programming...

    First post around here so go easy on me. Sorry about the blocks of text ill try to organize it. Intro Hello I am a member of a team that is assisting in the development of an student designed electric racecar. More specifically we are assisting in the design and prototyping of the motor control...

    Good Day to You all I Have a little problem;I was planing to build my own bl-dc motor for my Ev But Due to the high cost of thr Indudtrial BLDC i plained to make my own bldc from an Ac Motor Stator. Key features of the motor are -High initial torque -Great efficiency(so I am...
  11. Controllers
    Hi I am searching for a special kind of controller for 3 phase motors. The difference between my request and normal BLDC-controller is that I do not need the PWM and sensing. I have tried to google a hex-program that do not have the PWM included, but all is using PWM to regulate the speed of...

    Hey guys, I'm new to this site, and am a university student studying Electrical and Electronics engineering. I just completed a design project controlling a BLDC motor (pretty low powered at 60V, and giving output rpm of about 6000rpm). Now I had an idea where instead of using a single BLDCM...

    Has any one had any experience doing business with Chris at Lowcarbon-idea. They have a BLDC system that looks interesting. I have not seen any examples of conversions using BLDC, but the efficiency makes that look like a good choice.
