Project overview

This project presents in details how to configure a VESC board (Vedder Electronic Speed Control) :

  • Make the wiring and the required electrical connections to use this electronic board in order to control an electrical bike engine (as well as other types of engines such as DC, brushless)
  • Configure an electronic VESC board with a dedicated program (VESC Tool) in order to control an electrical bike engine with an electrical scooter type accelerator throttle.

Special thanks

The VESC card and the VESC Tool were designed by Benjamin Vedder VESC Project


Merci/Thanks/Danke Schön Benjamin Vedder :)

Warning

  • /!\ Do not unplug the engine when the battery is plugged in !
  • Reversing is not possible with this type of engine.

When you attempt to reverse with your installed device, the engine opposes a resistance, this is supposed to happen. There is way to facilitate reversing through special settings indicated by the acronym (M.Ar).

Moreover, the implementation of a master switch that cuts the main power (Safety circuit breaker) will hold the engine at rest. You will then be able to reverse.


  • In the program, when you have a number with a decimal, you must use a comma (example: -0,10) and not a dot (-0.10).

Useful links


  • Realization of the mechanical part (First version) : Mécanique V1 NOTE : This solution is not retained because it is too difficult to set up and remove.
  • The second version is similar to the third version. It is however less aesthetic. It is therefore not described here.
  • Realization of the mechanical part (Third version) : Mécanique V3

Design brief

For who : For all individuals who wish to enhance their mobility using an electrical bike engine.

For what : For children's bikes, hemiplegic quadricycles, scooters to tow wheelchairs (trotti)

How : By inserting an engine in the wheel using a Dibond flange (Documentation in the works) and by controlling the engine with a dedicated electronic card (VESC).

How much : Thanks to our partnership with La petite Rennes we can provide you with a battery free of charge, a battery charger and an electrical bike engine. In exchange you will be asked to take photos and make videos of your work in order to showcase your project.

You will nonetheless have to purchase components on the internet:

  • 1 VESC card: VESC electronic card
  • 1 cable for the hall effect sensors : TORQUE ESC Sensor Wires $6.99 (you only need to check the corresponding checkbox after you've bought the card)
  • The handle of an electrical scooter : Handle
  • 2 Manfrotto clamps to connect the chassis on your chair: Manfrotto clamps

Where : At the Humanlab or at a FabLab near you : FabLab maps by Makery

cost-efficient alternative to the VESC card NOT TESTED

  • There are other engine controlling electronic boards that are 10 times cheaper but these cannot be reprogrammed. This means you cannot select the speed at which the vehicle goes nor adjust the acceleration curve, you can find these here:

ESC low cost banggood

ESC low cost amazon


Optional

  • Stabilized powering to test if you don't have a battery
  • Additional cabling for extension cables if needed
  • Cable gland to seal the cable feedthrough

  • Acceleration handle = 8 €

Fabrication time

Fabrication time is given on an indicative basis and may vary, ref : Murphy's Law

FW 02 wiring.jpg


--> WARNING - (This step is now obsolete since we've chosen a new board provider)<-- - Wiring if use of a naked VESC board

Strip and tin the power supply wires and then cut back so that the stripped wires are not too long.

BALa0ZVr o.jpg QI4Jvynz o.jpg



Wrap the capacitor's lugs (holding parts) and then solder them (WARNING You have to solder the capacitor according to its polarity. The + (longest lug) on the red wire and the - (shortest lug) on the black. Then check the continuity of the wire with a multimeter and the insulation of one wire in relation to the other.

YLaFF5AM o.jpg BNy8yi8P o.jpg


Solder the power supply wires to the board by first putting tin on the + and - terminals and then placing the wires directly on them.

Tin the other two extremities of the wires.

Tin the three ends on the board, then the two ends of the cables that will feed the three electromagnetic coils of the motor (three-phase cables).

Solder them flat on the three previously tinned ends of the board.

Programming the electronic board

Preliminary step

///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

To enter the software in the board you will need to connect the board via usb AND power it from the bike battery (or a laboratory power supply) thanks to the 2 black and red wires.

Step by step software configuration

You will first need to download the software, you will need to purchase it ... for 0€ But you can also support the project by purchasing the software VESC Tool

Open the VESC Tool software.

A picture is worth a thousand explanations! You will be able to edit the tabs by following the mouse cursor on the images.

You might get a message the first time you open the software on udev rules. Click Yes to install them.

VESC Tool>Connection tab

In Connections tab>USB Serial, click on Refresh serial port list (Baud Option on 115200)


Connection-Serial-refresh.png


If no port is detected, leave the USB cable plugged in, and restart the software.

Then click the Connection icon.

See the original documentation in English if needed. Documentation

WARNING: the wrong firmware can permanently damage the board if it is not the right firmware! Select the board version in the left window (V 4.12) and VESC_default.bin in the right window.

Upload the VESC firmware VESC_default.bin corresponding to hardware v4.12.

Information message: the card configuration will be overwritten by the new firmware.


7 Firmware alerte effacement.png


Once the new firmware is uploaded, please wait the required 10 seconds and then disconnect the power from the board.


8 Firmware upload 10seconds wait.png


Message informing that the Firmware is uploaded. Wait for at least 10 seconds, then disconnect the USB and then reconnect.


10 Firmware message reboot.png


Reconnect the board

13 MS General Voltage.png


14 MS General Voltage Apply.png


VESC Tool>Motor settings>General>RPM

Indicate the maximum value of motor rotation in the MAX ERPM parameter (12000RPM here) (revolutions per minute). If you want to limit the speed of your device this is where it is controlled, feel free to test it.

- (M.Ar) - If you want to facilitate reversing (free wheel to allow reversing) you have to indicate this value in the max ERPM reverse box : -0,10


15 MS General RPM.png


VESC Tool>Motor settings>Wattage

Indicate the power of your engine in the Maximum Wattage box: 250W here

- (M.Ar) : you need to indicate this value in the Maximum Breaking Wattage box : -0,1W

VESC Tool>Motor settings>Temperature

There is nothing to change on the Temperature tab.


17 MS General Temperature.png

VESC Tool>Motor settings>Advanced

There is nothing to change in the Advanced tab.


18 MS General Advanced.png


VESC Tool>Motor settings>BLDC>General

On the left menu go to: Motor settings > BLDC then on the central window select the General tab. Copy the parameters of the following picture. In the Sensormode setting choose "Sensored".


19.png


In the bottom window on the "detect BLDC parameters" tab :


20 MS BLDC General Detect.png


Click on the icon of the triangle in a circle (play icon) (WARNING: this will start the engine).

Make sure that the motor is not under load (that nothing brakes it or prevents it from functioning).


If you use the MHK power bench, the belt must not be tensioned at all.


21 MS BLDC General Detect message.png


You get the hall sensor table of your motor (you can record and archive these parameters) :
