Design of Drive Motor for Quadrature Encoder Based on STM32

1. Encoder principle

What is orthogonal? If the two signals are 90 degrees out of phase, the two signals are called quadrature. Since the two signals differ by 90 degrees, the direction can be determined according to which of the two signals comes first.

ec11 encoder performance description The ec11 encoder consists of a photoelectric code disc with an axis in the center, which mainly uses the principle of photoelectric conversion to output three groups of square wave pulses A, B and Z phases.

How does the encoder measure position, speed, and angular acceleration In the electric drive system, it is the core component used to measure the motor speed and rotor position. In the photoelectric encoder, its shaft is connected with the shaft under test, and the shaft under test drives its shaft to rotate, and then the measured physical quantity is converted into a binary code or a series of pulses.

How much do you know about the anti-interference principle of okplazas.com rotary encoder Rotary encoder is a kind of precision electronic components, and it is required to be anti-interference to the environment of use. Today I will take you to understand the design principle of anti-interference system of rotary encoder. How to judge whether it is the fault of the encoder itself? Still interference.

Servo motor encoder learning Regarding the encoder of the servo motor, only the main points are introduced here, too many principles can not be remembered, a concise introduction. Encoder: Incremental 2500 lines, 8 poles.

What are the interference sources of the cablerope displacement encoder What are the interference sources of the cable/rope displacement encoder-okplazas.com displacement sensor What are the interference sources of the cable/rope displacement encoder

Encoder pulse number selection It can be calculated like this, you must first determine the maximum operating speed of the membrane per second (such as 500MM/S). And what is the highest frequency of the collection you count (for example, 30KHZ). So you can calculate the circumference of the measuring wheel 75*3.14=235.5MM, so use 500/235.5=2.123, which is the number of turns per second. Then use this number of turns * pulse number of the encoder not to exceed 30KHZ.

FB9x series self-aligning machineresolver-the application field of absolute shaft angle encoder The self-aligning machine/resolver was mainly used in places requiring high precision and high reliability, such as aviation, aerospace, ships, weapons, radar, communications and other fields. And they have not been well promoted in other fields because it outputs three-phase AC signals, which must be processed by the digital processing part after the angle signal is turned into a digital quantity before it can enter the computer or other equipment, and this digital processing part

Incremental encoder signal output TTL level, 5V differential, long-line drive, RS422, etc. What are the differences After talking about the sine-cosine analog signal output and subdivision of the incremental encoder, this time we will talk about the square wave pulse digital signal of the incremental encoder. Incremental square wave pulse digital signal may be simple, but it is still difficult for many people to define and distinguish clearly, and mistakes abound on such a simple problem. It actually determines whether the encoder signal reception can be well matched, and high-quality transmission and reading, and signal anti-interference ability.

What is a shaft encoder A shaft encoder is a device used to measure the rotation angle of an object. From the measurement principle, there are: photoelectric type, grating type, magnetoelectric type, self-aligning machine/resolver type.
