Why use st7litex mcu l.jpg
Why use ST7liteX MCU?

  • Quick and accurate compute.

  • Easy to upgrade and add new functions

  • Compatible with different sensors and requirements

  • Close loop control

  • Cheaper price & high quality performance


Features of demo kit l.jpg
Features of demo kit

  • Adjustable speed steplessly

    • Throttle

      Holler sensor

      input : 5V output : 1.2V ~ 4.7V

  • Cruise. Run the bicycle in a preferred speed.

    • No need to grasp throttle

  • Speed detection & display.

    • Holler sensor

      x pulses in a cycle

Rider force

Rider force and electric power as one, push the rider and vehicle into operation

Intelligent sensor

controller

Electric power

motor

  • '1+1' assistant. The machine provides the same power as the rider does.

    • Need a torque/speed sensor for close loop control

k, ∫ dx, dy/dx

PID control

Speed sensor

PWM control

Torque sensor

  • Voltage low detection & warning.

  • Over current detection & protection.

Close loop

for better

performance

speed

Restore time

t

Brake or motor jam,etc

  • Run away protection. Cut off the motor power in case of uncontrolled situation, and restore the speed in a safe slow process.


Schedule l.jpg
