Application of electric bicycles in chip technology

Electric bike is a green vehicle with a power-driven, pedal-driven, power and other effects of the foot and use. Battery through a controller to a motor power transmission, the motor on the wheel, the motor bicycle driven rotary travel.
folding electric trikes controller connects a governor handle the shaft with the pedal assist sensor, electric bicycle handle rotation speed allows the controller to detect the different voltage value, the controller according to the voltage value of the size, analog adjustment applied to the motor voltage level, so as to control the motor speed.
The controller brushless motor control method is based on the position of the motor feedback signals to control the three-phase motor drive upper and lower arms MOS tube on and off, enabling electronic commutation. three wheel electric tricycle use SPMC65P2404A as a master MCU.
