    FLIPSKY new 20s 100A tiny controller (vesc based)

    to better dissipate the heat, since I am using it at maximum power

    FLIPSKY new 20s 100A tiny controller (vesc based)

    I use the controller without the box and I changed the aluminum block of the mosfets for a copper one

    Spain. Cools fast because it has an improved heat sink

    exact, sensor is not connected

    FLIPSKY new 20s 100A tiny controller (vesc based)

    It is the bms that had it set to cut at 80a. then when i got home i turned it up to 95a

    there are holes in the back of the piece of the image. through those holes you can push the bearing

    if you mean the brake system that works when you turn the pedals back, the answer is no, because when you rotate the pedals in an anti-clockwise direction with this engine, the chain does not move

    Therefore, it is necessary to advance the measuring magnet a little to prevent the above described from happening. In the video that was shared previously, it is indicated how the magnet should be rotated

    Yes what happens is that the torque sensor works with the angular offset between the magnets, the more force you apply to the pedals, the more angular offset there is between the magnets and the motor helps more. But if the angular offset is very large, the motor stop. This is due to the...

    You can also arm the bottom bracket without the spring, which will only work the pass sensor and not the torque + pass sensor. I tell you if you can't find material to make a new spring. You can arm without spring and calmly look for a suitable material, then you put it

    I had to drill the shaft to remove the original spring, since it was very tight: https://www.instagram.com/p/B39c2QXB2LZ/ I drilled it with a dremel, a tungsten drill and a tungsten strawberry. Then I hit the spring from behind

    New "Lingbei MM28.250 torque sensor mid drive"

    What is happening to you is due to an incorrect offset between the sensor magnets. When you feel the intermittency is when you lower the left pedal because the natural torque of the bottom bracket axis helps to further offset the magnet that is more central, however when you lower the right...

    Is it possible to replace the STM32F031C6T6 of the lingbei controller with an STM32F103C8T6?

    Congratulations stancecoke. Very good calculations very good modeling and very good approximation. Adjusting the parameters a bit: a = 3; b = 10; therefore I = 22.5. we assume f = 0.9 approximately, but L is more difficult to give an approximate value because measuring directly can give a value...

    I saw in a part of the forum that the motor controller uses a stm32 micro controller. Is it correct? If so, it could easily be programmed in arduino IDE with a st link v2. :D Does anyone know where to find any programming code of any controller? :wink: having a code, it can be edited or new...

    Hello stancecoke, the analysis you did in the images are correct. Here I put more images of the spring, I have repaired it because it was broken: https://www.instagram.com/p/B39eVk8hKgt/ https://www.instagram.com/p/B39cwD-BjDN/ https://www.instagram.com/p/B39cxx6hH3t/...

    mm28 really uses a torque sensor, use a spring between the axle and the transmission to the pinion.It has two magnets and measures the offset between the two to record the displacement of the spring. The transmission may have a small displacement with respect to the axis. One magnet is attached...

    I measured it directly with the throttle, and without the chain in place so that it didn't force
