VESC V4 Based on Benjamin Vedder Controller for DIY Electric Skateboard Electric

FRC VESC Sina Wave Controller  by Benjamin's Robotics for Electric Skateboard 

Features

• The hardware and software is open source. Since there are plenty of CPU-resources left, the customization possibilities are almost endless.
• STM32F4 microcontroller.
• DRV8302 MOSFET driver / buck converter / current shunt amplifier.
• IRFS7530 MOEFETs (other FETs in the same package also fit).
• 5V 1A output for external electronics from the buck converter integrated on the DRV8302.
• Voltage: 8V – 60V (Safe for 3S to 12S LiPo).
• Current: Up to 240A for a couple of seconds or about 50A continuous depending on the temperature and air circulation around the PCB.
• Sensored and sensorless FOC wich auto-detection of all motor parameters is implemented since FW 2.3.
• Firmware based on ChibiOS/RT.
• PCB size: slightly less than 40mm x 60mm.
• Current and voltage measurement on all phases.
• Regenerative braking.
• DC motors are also supported.
• Sensored or sensorless operation.
• A GUI with lots of configuration parameters
• Adaptive PWM frequency to get as good ADC measurements as possible.
• RPM-based phase advance (or timing/field weakening).
• Good start-up torque in the sensorless mode (and obviously in the sensored mode as well).
• The motor is used as a tachometer, which is good for odometry on modified RC cars.
• Duty-cycle control, speed control or current control.
• Seamless 4-quadrant operation.
• Interface to control the motor: PPM signal (RC servo), analog, UART, I2C, USB  or CAN-bus.
• Wireless wii nunchuk (Nyko Kama) control through the I2C port. This is convenient for electric skateboards.
• Consumed and regenerated amp-hour and watt-hour counting.
• Optional PPM signal output. Useful when e.g. controlling an RC car from a raspberry pi or an android device.
• The USB port uses the modem profile, so an Android device can be connected to the motor controller without rooting. 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).
• Adjustable protection against
  • Low input voltage
  • High input voltage
  • High motor current
  • High input current
  • High regenerative braking current (separate limits for the motor and the input)
  • Rapid duty cycle changes (ramping)
  • High RPM (separate limits for each direction).
• When the current limits are hit, a soft back-off strategy is used while the motor keeps running. If the current becomes way too high, the motor is switched off completely.
• The RPM limit also has a soft back-off strategy.
• Commutation works perfectly even when the speed of the motor changes rapidly. 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.
• When the motor is rotating while the controller is off, the commutations and the direction are tracked. The duty-cycle to get the same speed is also calculated. This is to get a smooth start when the motor is already spinning.
• All of the hardware is ready for sensorless field-oriented control (FOC)

Company introduction:  

Dongguan Freerchobby Co., was established in 2011. We are an RC model manufacturer specializing in designing&producingRC car

 models, BLDC brushless motors, rc tools and accessories. 

About our rc car department,  We have a design team for 8 people

with many years’ RC experience, the driver who gets awards in the

national championship and merit awards in the domestic and inte-

rnational opening tournament joining us makes our products more

professional, market oriented and diverse. Now our company has

released 1/8th SC truckand buggy ,1-10 scale competition On road 

kit and RTR on road car to the market. 

About our brushless motor department, our  technician, with 12 years’ motor design experiece, designs various size motors for rc bobby

plane, multicopter, such as 28, 35, 42, 50, 63 series.

And for other industrial,such as electric skateboard, electric bike, electric paramotor,paraglider,drone, electric surfboard,electric car,boat etc. We have  motor 8085, 80100, 12090, 120100, 154120,23850,238100,202150,240110,240150 ect.
