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. Adjustableprotection 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).

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). A GUI with lots of configuration parameters Adaptive PWM frequency to get as good ADC measurements as possible.
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 – 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).

For instructions on how to program them specifically for your motor please see for videos. If you require bulk quantities please contact us for pricing. Third,we test every vesc with our company's motor. Second,install firmware,setting BLDC,sensorless,PPM,current values.
Our testing and set up procedures of each VESC are as follows : VESC is programmed with bootloader. All our VESC are sent out debugged and programed to our motor parameters unlike other suppliers we debug all our VESC. ( not shown fitted in photo's but will be fitted to all ) Fully programmable open source VESC the best motor controller on the market manufactured with CE and ROHS testing. 3) Protective shrink-wrap in sunbright yellow. 2) Mosfets layout redesigned so they are all now on 1 side of the board for improved protection and heat dissipation. 1) Massive aluminium heatsink for greatly improved heat dissipation. We use these vesc in our own dual motor mountainboards with 10s battery and 3000 watt 300 kv motors ! and they are super reliable. We believe these are one of the best designed and most reliable, rohbust VESC'S on the market. We have improved and redesigned the original VESC with the following upgrades these VESC are designed for higher performance and reliability and particular suited for the demanding and punishing E BOARD usage but have many other applications.
