Several lines of Santana 3000 throttle

Santana 3000 throttle has three tubes, and the inclined tube is a vacuum tube, which leads directly to the inside of the throttle.

The throttle drive motor is generally a stepping motor or a DC motor, and their control methods are also different. H-bridge circuit structure is often used to drive the stepping motor, and the control unit controls the stepping motor by controlling the number, frequency and direction of pulses. The level controls the rotation direction of the stepping motor, and the number of pulses controls the rotation angle of the motor, that is, when a pulse signal is sent, the stepping motor rotates by a stepping angle, and the pulse frequency controls the motor speed, which is proportional to the pulse frequency. Therefore, by adjusting the above three parameters, the precise positioning and speed regulation of the motor can be realized.
