    Nanjing far driver controllers

    I bought the goods used, not directly from the seller. But when I studied the characteristics, many sources pointed to 660a. For example https://aliexpress.com/item/1005002247242962.html

    Nanjing far driver controllers

    Does anyone have a 72490 controller? I bought it in China, the description said 330A battery current and 660A phase current. However, in the settings, I cannot specify a phase current greater than 490 (which is logical, given the name of the controller 72490) Has anyone experienced this product...

    Votol EM-100 & EM-150 controllers

    It looks like I also have a faulty microcontroller, or faulty software. Can anyone help me get the firmware on the EM150S :idea: :roll: UPD I checked the power supply of the microcontroller, BCC and VDD voltage is 3.2 V, but the LED does not blink. Perhaps the microcontroller is defective or...

    Votol EM-100 & EM-150 controllers

    Hi friends! Your help is needed again. For half a year I used the EM100S controller and it worked well, however I wanted more power and bought the EM150S. I received it yesterday and was unable to connect to my computer. I've tried changing different software, swapping RX and TX but that...

    Votol EM-100 & EM-150 controllers

    You are right, I did not notice that I did not have a check mark next to the HDC Enable menu, I tried ticking the box and set the setting to LOW to 99% at the same time, the maximum current increased to 45 amperes, but I did not try to reduce the value to 1 percent to check the dependence, I...

    Votol EM-100 & EM-150 controllers

    Today I tried to change the LOW value by 99% and measure the maximum current at 20% of the maximum rpm - it turned out to be 31 amperes. With a decrease in the value to 0, the current was about 41A. This means that in my case the setting does not work correctly :( Perhaps the em100s version the...

    Votol EM-100 & EM-150 controllers

    strangely, I read earlier that these values ​​affect jitter and motor timing. I understand correctly that if I set the maximum value in the field - low, I will get the maximum current in all three modes? Ebs true value 30% , reverse not used. Controller em100s, motor -surron bike, 50...

    Votol EM-100 & EM-150 controllers

    Thanks a lot for the link to the display, I will try to buy it.I am now far from the bike, but I have memorized the settings and can show them. On the contrary, low medium and high are really worth a value of 0, I thought it does not affect the torque in any way? I previously read that these...

    How are you doing with creating instructions? We are looking forward to it :) I don't really understand how to use all the available programming functions, and I don't know how to keep the maximum torque at low engine speeds

    Votol EM-100 & EM-150 controllers

    Thanks for the answer, but unfortunately it doesn't work for me. If I set the minimum mode, the torque is limited, the motorcycle cannot turn the wheel in place. If I limit the revs with the speed limiter function, good torque is maintained - https://youtu.be/yApsksY7Yeo Can you tell me how to...

    Please help to customize the function in the picture? I want to set the "Speed limit" using the programmable buttons, but I don't know which wire to use to enable it? Does anyone know how to connect correctly? Low medium high mode is not suitable as these modes limit the torque and the speed...

    What do you think the display can be used to correctly display the speed, voltage and operating mode of the controller? I want to see the low average and maximum power mode, but I do not know which display will work. also i can't find the wire for the external temperature sensor, can you help...

    Can you please tell me if I can use 3 modules 0-140 volts for serial connection? I need about 400 volts to charge the 96S battery.. I am worried that the diode bridge or output transistor may burn out :bolt:

    Sur-Ron - New Mid drive Bike

    different versions are sold in China, it sounds strange but em100s can have several modifications, usually it is 100 amperes, but I have a 150 ampere version, it was model em100s-72350. Battery is original l1e 2020

    Sur-Ron - New Mid drive Bike

    Today I managed to configure the controller, the problem was that the controller incorrectly determined the voltage, 10 volts below the real value, this triggered the overcurrent protection. I changed the value manually and the controller is delivering 140 amps of battery current. The bike is...

    Today I managed to measure the current on my surron motor, Votol em100s controller. the maximum battery current was 48 amperes, and the phase current was -197 amperes. this is significantly lower than I expected. the settings are set to the maximum current, but the speed is limited to 25...

    Hi guys. Excuse my English, I use a translator. Has anyone used Chinese Votol controllers? Yesterday I connected the EM100S http://www.votol.net/en-us/controller/26.html controller to my Surron, it is written that this controller can 140 battery current and 350 ampere phase current. According...

    I have an EM100C (72350) controller, unfortunately I can't set it up to work well with my Surron bike motor (5 pair). At low revs, it works well, but as the accelerator increases, the current rises, the revs drop, the rotor starts to heat up. I have tried changing the degrees of the halls...

    Hi guys, I’m sorry if my english is wrong, I’m using a translator. Can you please, is it possible to configure the controller EM100S in the engine speed control mode and not power? I really like it when the engine has maximum torque at low revs, as it is implemented in Bafang BBS HD motors . If...
