Re: Votol EM-100 & EM-150 controllers

Try to disable SW at PB3, as well as rest of all the unnecessary "features" (like PD0, PA12, you decide). I suggest to start as clean as possible and then give it a spin. Make sure settings on page 3 are set properly (especially hall related). BTW I also have some controllers reporting bo...

Re: Votol EM-100 & EM-150 controllers

anyone else notice in the newer batch of em150SP sport mode is activated a little differently?, i have a total of 3 motors (qs 138 mid) and 3( em 150sp). My very first controller, its sport mode was how everyone describes here, simply take the yellow/white and bridge it to ground for continuous spo...

Re: Throttle dead zone fixes

You and I have very similar throttle profiles... https://i.imgur.com/ioOF3au.jpg You can raise the starting voltage output by adding some resistance to the ground line of the hall sensor. Start with a 10 K, mini, multi-turn trim pot, set at the least resistance between the two legs you will use. Th...

Re: Votol EM-100 & EM-150 controllers

Hi guys. I wanted to share my experience with the EM-200 and the 138 70H QS 3000W. Received my combo two days ago and it wasn't working well. The motor was giving strange buzzing noises right before it start spinning.The settings are done by the book. After few minutes of testing I decided to shut ...

Re: Votol EM-100 & EM-150 controllers

Normally you set higher flux weakening in sport than high as sport is intended to be the max setting, but it really doesn’t matter as long as you know what you want. is there any truth that a lower flux has more linear tq? where higher flux increases rpm but by diminishing a little bit of tq along ...

Re: Votol EM-100 & EM-150 controllers

It isn’t correct. If motor actually gets hot then it’s a pointer that efficiency is low. To drive around with 5000 and high setting as default is not recommended, QSmotor gave 80/flux weakening compensation, 3000/flux weakening as max when i asked. Which seller is this? Doesn’t seem reliable. it is...

Re: Votol EM-100 & EM-150 controllers

That’s just the dual voltage setting. One level for full battery voltage and one for the more exhausted battery. I guess flux compensation is a parameter related to the max possible flux weakening current, possibly related to the motor inductance and the setting 0-3000 is fine tuning parameter. thi...

Re: Votol EM-100 & EM-150 controllers

The ramp up / ramp down setting at first settings screen doesn’t work in my (early model) controller but seems to work for others, you can try changing the ramp down settings to see if that helps. @overclocker: what bugs do you experience? what are you referring to on the ramp up and ramp down sett...

Re: Votol EM-100 & EM-150 controllers

hi I saw you posted posted you got the low brake to work? what is the difference between that and the high brake? I have the purple wire(high brake) going to my brake switch along with a 12v wire. this is how I was told the regen works. the only issue I have is when I let off the throttle my engine...

Re: Votol EM-100 & EM-150 controllers

I finally got the 138 mid motor and the votol em150 SP controller all hooked up to a homemade aluminum scooter I built. this thing is way overkill (it wheelies). one issue I’m having is there seems to be a lot of engine braking when you let off the throttle, kind of like regen and it’s very noisy!.....

Re: Votol EM-100 & EM-150 controllers

nice video!, any reason to solder the sport mode? or just keep it simple since its the only mode you use? for your busbar current you found 140 to be best? for the qs 138 motor is your shift angle -60? I believe mine came from factory at -120 soldered sport mode just to keep it simple, no button ne...

I just got my em150sp and qs138 motor connected to the software. Here is a pic of my throttle settings. when I twist throttle the motor doesn't move until about 1/4 turn of throttle. Is there any adjustment so it is more sensitive? and how do I know that it recognizes what full throttle is when it ...

Re: Votol EM-100 & EM-150 controllers

Same for me. Have the 150sp, but in the software , it set as em100 ok then no worries, I just read at beginning of this thread that all that is important is the phase angle and the poles for the manufacture to set up for you motor before they send out then all rest are up to you to change, like bus...

Re: bluetooth BMS?

i just connected a 21s bms with lcd 300 amp , once I turn on controller - voltage jumps around then goes to zero and stays there? I have all wires correct, I don't understand. also I cant connect to the lcd screen. says connecting to bms then turns off. anyone had experience with this? thanks

Re: Votol EM-100 & EM-150 controllers

Nice idea, i doubt you’ll need two motors though. That chassi won’t like high speeds so you can gear a single motor to 40mph and do all the drifting you want. I’d rather buy burnout tyres that creates pink smoke for the second motor money :mrgreen: :mrgreen: https://highway-max-coloured-smoke-us.my...
