For their operation, they use signals based on light, magnetism, or magnetostrictive material behavior. Since the distance between resets is variable, then can you take the encoder pulses into two channels on the card and use the second channel for Nevertheless, certain drive systems require a speed and/or position encoder for their optimal performance. The Encoders operate using various sensing technologies, with optical and magnetic being the most prevalent in modern robotics. So, the proper way, based on my understanding, to find speed is by using the following formula: (average_pulses / dt). What is an Encoder? An encoder is a device that converts mechanical motion into electrical signals, commonly used to detect the position, speed, and direction of a shaft.
