Writing the software is the remaining part.

All of the hardware is ready for sensorless field-oriented control (FOC).

This is to get a smooth start when the motor is already spinning. The duty-cycle to get the same speed is also calculated.

When the motor is rotating while the controller is off, the commutations and the direction are tracked.

This is due to the fact that the magnetic flux is integrated after the zero crossing instead of adding a delay based on the previous speed.

Commutation works perfectly even when the speed of the motor changes rapidly.

The RPM limit also has a soft back-off strategy.

If the current becomes way too high, the motor is switched off completely.

When the current limits are hit, a soft back-off strategy is used while the motor keeps running.

High RPM (separate limits for each direction).

High regenerative braking current (separate limits for the motor and the input).

Because of the servo output, the odometry and the extra ADC inputs (that can be used for sensors), this is perfect for modifying an RC car to be controlled from Android (or raspberry pi).

The USB port uses the modem profile, so an Android device can be connected to the motor controller without rooting.

controlling an RC car from a raspberry pi or an android device.

Consumed and regenerated amp-hour and watt-hour counting.

This is convenient for electric skateboards.

Wireless wii nunchuk (Nyko Kama) control through the I2C port.

Interface to control the motor: PPM signal (RC servo), analog, UART, I2C, USB or CAN-bus.

Duty-cycle control, speed control or current control.

The motor is used as a tachometer, which is good for odometry on modified RC cars.

Good start-up torque in the sensorless mode (and obviously in the sensored mode as well).

RPM-based phase advance (or timing/field weakening).

Adaptive PWM frequency to get as good ADC measurements as possible.

A GUI with lots of configuration parameters.

Current and voltage measurement on all phases.

PCB size: slightly less than 40mm x 60mm.

Sensored and sensorless FOC wich auto-detection of all motor parameters is implemented since FW 2.3.

Current: Up to 240A for a couple of seconds or about 50A continuous depending on the temperature and air circulation around the PCB.

Voltage: 8V вЂ“ 60V (Safe for 3S to 12S LiPo).

5V 1A output for external electronics from the buck converter integrated on the DRV8302.

IRFS7530 MOEFETs (other FETs in the same package also fit).

DRV8302 MOSFET driver / buck converter / current shunt amplifier.

Since there are plenty of CPU-resources left, the customization possibilities are almost endless.

The hardware and software is open source.

I have created an IRC channel on freenode where you can live chat with me and other users about VESC and my other projects.

Electric skateboard motor tutorial (KV, cells, etc.)Д«ecause information about the VESC is scattered all over the internet and a lot of information is in email conversations with me, I have created a forum dedicated to the VESC here.

Old post motor controller (just for reference).

osx and windows builds of BLDC Tool, Video logger etc.

Some screenshots of the configuration GUI (BLDC Tool):ДЄll files are on github to keep them up to date, so check these links on a regular basis:

This is an overview of the schematic (download a complete PDF here):

I really enjoy sharing knowledge, so I want to keep all the hardware and software open. This might sound a bit ambitions, but my goal is to make the best ESC available. I have made many updates to my custom motor controller recently and the old post is getting confusing with notes and updates, I decided to write a new post about it that hopefully is more clear, more complete and easier to follow.
