When choosing a servo motor encoder, several factors need to be considered, such as accuracy, resolution, speed, stability, reliability and so on. Below is an introduction to several common servo motor encoders and their characteristics:
(1) Optoelectronic encoder: Optoelectronic encoder is characterized by high accuracy, high resolution and high speed, which is suitable for applications with high requirements on position and speed. However, photoelectric encoders are more expensive and less suitable for low-cost applications.
(2) Magnetic encoder: magnetic encoder with high accuracy, high resolution, strong anti-interference ability and other characteristics, suitable for industrial automation in the field of position and speed requirements of high application scenarios. At the same time, magnetic encoder price is relatively low, cost-effective.
(3) Coaxial encoder: Coaxial encoder can be directly mounted on the servo motor shaft, with a simple structure, easy to install and other characteristics, suitable for space constraints or requirements of compact application scenarios. However, the coaxial encoder's accuracy and resolution are relatively low, which is less suitable for application scenarios with high requirements for position and speed.
