    Low Speed Throttle Control w/ High Torque

    Thanks Scianiac. You're correct, I have only a basic understanding of the controller hardware and software. When it comes to code and chipsets, I'm outside my knowledge zone. Sounds like using "PID controller" interchangeably with "speed controller" is inaccurate. I guess PID is used anytime...

    Low Speed Throttle Control w/ High Torque

    Thanks Nixunen. I visited their website and unfortunately the size that I would need (6F) is on indefinite pre-order and there's no indication of pricing. Seems like it could be a future consideration but is still not ready for mainstream. Please let me know if you have additional information.

    Low Speed Throttle Control w/ High Torque

    Thanks again scianiac. I have a Flipsky ordered and will start to build my experience with VESC. By my understanding, the critical difference here is that VESC will allow you to control the current/torque of the motor whereas all the other common controllers are PID architecture and therefore...

    Low Speed Throttle Control w/ High Torque

    Thank you both for your feedback. It sounds like VESC would be worth exploring. I would need to source from a decent mass-production factory as a opposed to fancy units retailed by folks like Trampa and Tronic. Have you come across any discussions regarding suppliers with strong reputations?

    Low Speed Throttle Control w/ High Torque

    Haha, I know what you mean. Just to be clear it's 300Nm at the rear hub which is enough to pull you up a 50% grade with cargo but a long way from 300Nm at the motor shaft or gearbox output. Like I said above, I own a Gogoro which has similar levels of wheel torque and does a nice job of...

    Low Speed Throttle Control w/ High Torque

    Correct. I'm using a CA as a display with an Analogger for data collection at the moment. Because a CA won't be part of a production vehicle, there's minimal value in developing a solution that's dependent on it. I'm trying not to develop custom hardware solutions under the assumption that...

    Low Speed Throttle Control w/ High Torque

    Thanks again. All are sensible and clever suggestions and could make for some enjoyable experimentation. I do have a CA and have waivered about using it's "throttle management" functionality. My conundrum is that I'm working to build a commerical product and therefore need to steer clear of...

    Problems with Votol Em200sp and low acceleration.

    Presumably you already have this manual. If not, does it help you? My experience is that some portions are helpful but other parts contradict or simply use incorrect wording and therefore the meaning is lost.

    Low Speed Throttle Control w/ High Torque

    Hi amberwolf. My apologies for overlooking your reply until now. Yes, many of the controllers allow for throttle voltage threshold adjustment. You're correct, eliminating dead zone is one of the important pieces of the puzzle. Motors that react slowly to throttle input lead the rider to...

    Low Speed Throttle Control w/ High Torque

    Hi. I'm building a offroad utility motorbike focused on torque and control rather than speed and thrills. Since starting the project one year ago, it's been a goal for the bike to be friendly to inexperienced riders while still providing impressive hill-conquering capabilities with a heavy...

    Best controller for QS138 V3 70

    Your components will generate heat proportional to the current (amps) and their resistance. Quite important, heat is generated as the square of the current (it’s not linear). Therefore, your duty cycle logic cannot be linear. In addition, there are matters of heat resistance and dissipation. If...

    Kelly KLS4812S Programming interface cable?

    Hi. Not much I can help you with but can commiserate and share that I had many of the same experiences with a Kelly KVD7212N and KLS7212S. The “regen” behavior when coming back onto throttle while moving was deal breaker for me. It was especially pronounced when operating in the lower “1” and...
