After the bluetooth is connected, 4 green buttons will be in the enabling state, control the switch of motor respectively, turn to, electric current ring, speed ring. The current loop refers to a current feedback system, and generally refers to a method for connecting an output current to a processing link in a positive feedback or negative feedback manner, mainly for improving the performance of the system by improving the stability of the current. The speed loop is then referred to as a speed feedback system. Their main functions are to make the error less and less, to make the control precision higher and more accurate and more rapid and to realize automatic control. The page can realize the setting of the motor acceleration, the given phase current, the given rotating speed, the maximum current, the maximum rotating speed and the given duty ratio, if the set value is correctly received by the lower computer, the received value is fed back under the corresponding input value, and the condition of whether an invalid value is sent or not can be effectively known. The motor acceleration is understood to mean how fast the motor achieves a given rotational speed. A given phase current refers to the current flowing through each phase load in a three-phase power supply. The given rotating speed is the rotating speed when the motor stably runs. The maximum current is the maximum allowed phase current, and if the maximum current input value is exceeded in the operation process, the motor starts protective measures and stops running.

Each item of data is updated in real time along with the state change of the motor, so that the real validity of the data is ensured. The Pulse-Width Modulation (PWM) is performed in A, B, C-phase PWM duty ratio, the Pulse Width is the time of outputting high level in one period, the duty ratio is the proportion of outputting high level in one period, and especially in the aspect of controlling the rotating speed of the motor, the technology can greatly save energy. PWM has very strong noise immunity, and has characteristics such as saving space, relatively economy.
