In this article, we’ll discuss the various application fields and working principles of the AS2702-16.

Application Fields of the AS2702-16

The AS2702-16 can be used in a wide range of applications, including brushless dimmers, low voltage stepper motor applications, and robotic control systems. The device is designed to work with BLDC motors and provides a digital signal for each pole, allowing for precise motor speed, position, and torque measurements. It is also able to detect anomalies in the motor or the magnetic field, making it ideal for motion control purposes. Additionally, the AS2702-16 is compatible with PWM, providing greater flexibility.

The AS2702-16 is also ideal for use in industrial applications, such as in factory automation machines, conveyor belts, elevators, and more. It can be used to measure the speed and position of moving parts and provide a digital signal for feedback control. The device is rugged and reliable, making it well-suited for harsh industrial environments.

Working Principle

The AS2702-16 is a hall-effect sensor, which utilizes the Hall effect to measure the position of a permanent magnet or an electromagnet. The device consists of 16 channels, each of which corresponds to a motor pole. The signal from each pole is amplified and then digitized, providing a digital output signal that can be used for measurements. The device also contains an internal microcontroller which is used to diagnose any signal anomalies or faults in the system.

When the motor is moving, the Hall effect sensor detects the magnetic field of the motor pole and generates a digital output signal. This signal is then fed to the microcontroller for processing and analysis. The microcontroller is able to detect any discrepancies in the signal or magnetic field, allowing the system to diagnose any errors in the motor or the sensor.

The AS2702-16 is also able to measure the motor speed and torque by detecting changes in the voltage level across the poles. This is done by measuring the differences in the signals from each pole and calculating the speed and torque based on the difference. This provides a more accurate measurement than traditional tachometers, which measure the speed of the motor directly.

Conclusion

The AS2702-16 is a 16-channel hall-effect sensor designed for use with dc motors in brushless dimmers and low voltage stepper motor applications. It has a wide range of applications, from industrial processes to motion control systems. The device utilizes the Hall effect to measure the position of a permanent magnet or an electromagnet and provides a digital signal for each pole. It also has a self-diagnostic feature that allows it to detect any signal or magnetic field abnormalities. This makes it an ideal choice for applications requiring precise motor speed, position, and torque measurements.
