The digital tachometer will read the received digital pulse signal (sent by the sensor) directly into the counting port of the cpu after processing, calculate the speed and the position of the pointer by the software, and then through the control port of the cpu, amplify and drive the stepping The motor rotates in the positive and negative directions, indicating the corresponding speed value (the pointer is directly mounted on the rotating shaft of the stepper motor), and the stepper motor takes only 1/3 of a step.
1. The pointer with large static moment is not easy to shake, and the anti-vibration performance is strong.
2. It adopts a single-chip microprocessor through software design, so it has high precision and strong anti-interference.
3. The hour meter uses liquid crystal display without mechanical parts, so it is more reliable and more contemporary.
Because the pointer indication conforms to traditional visual recognition habits, and is convenient for computer remote processing and networking requirements, digital stepper motor meters are the development trend of modern automobile meters and motorcycle meters. Switec's stepper motors have been widely used at home and abroad. Used in various automobiles, motorcycles and engineering machinery instruments. The miniature stepping motor for vehicles is a special new type of automobile instrument accessories. The instrument designed with it not only conforms to the traditional visual recognition habits but also meets the requirements of digital processing. It is an ideal accessory for modern instruments.
