Functional translation

1、 Both hardware and software are open source . Because there is a lot of CPU resources , The possibilities for customization are almost endless .

2、STM32 F4 Micro controller .

3、DRV8302 MOSFET Driver / Buck Converter / Current shunt amplifier .

4、Irfs75 30 MOEFET（ Others in the same package FET Also suitable for ）.

5、5V 1A The output of the external electronics from the buck converter is integrated in DRV8302 On .

6、 voltage ：8V to 60V（3S to 12S LIPO Security ）.

7、 electric current ： As many as 240A, For a few seconds , Or about 50A, It depends. PCB Ambient temperature and air circulation .

8、 since FW 2.3 since , It realizes the sensorless and sensorless focusing for the automatic detection of all motor parameters .

9、 be based on ChibiOS /RT The firmware of .

10、PCB Size ： slightly smaller than 40mm×60mm.

11、 Current and voltage measurements at all stages .

12、 Regenerative braking

13、 It also supports DC motors .

14、 Sensing or sensorless operation .

15、 A with a large number of configuration parameters GUI

16、 The adaptive PWM Get the best possible frequency ADC measurement .

12、 be based on RPM Phase advance of （ Or time / Field weakening ）.

13、 Good starting torque in sensorless mode （ Obviously also in sensing mode ）.

14、 The motor acts as a tachometer , For the modified RC The car measures the distance .

15、 Duty cycle control , Speed control or current control .

16、 Seamless four quadrant operation .

17、 Interface control motor ：PPM The signal （RC servo ）, simulation ,UART,I2C,USB or CAN Bus ./18、 wireless Wii Nun Chuk （NYK-KAMA） adopt  I2C Port control . This is very convenient for electric skateboards .

18、 Ampere hours and watt hours consumed and regenerated .

19、 Optional PPM Signal output . Helpful , For example, control RC Cars from raspberries PI or Android equipment .

20、USB Port uses modem Profile , therefore Android The equipment can be connected to the motor controller without rooting . Due to servo output , Odometer and extra ADC Input （ Can be used for sensors ）, This is the perfect modification of the RC car control from Android（ Or raspberry pi）.

21、 Adjustable protection

22、 Low input voltage

23、 High input voltage

24、 High motor current

25、 High input current

26、 High regenerative braking current （ Independent limits of motor and input ）

27、 Rapid duty cycle change （ steep hill ）

28、 High speed （ Each direction is restricted individually ）.

29、 When the current limit is hit , Use the soft back off strategy while the motor continues to run . If the current becomes too high , The motor is completely cut off .

30、RPM Restrictions also have soft backoff strategies .

31、 Even if the speed of the motor changes quickly , Reversing also works well . This is because the magnetic flux is integrated after zero crossing , Instead of increasing the delay based on the previous speed .

32、 When the motor rotates when the controller is turned off , Track commutation and direction . The duty cycle for obtaining the same speed is also calculated . When the motor has rotated , This is a smooth start .
