Key factors impacting motor encoder selection！

Motor Type
When selecting components for a closed loop control system, the motor encoder choice is first determined by the type of motor chosen in the application. The most common motor types are:

• AC Induction Motors: These motors are popular choices for general automation machine control systems as they are economical and rugged. Motor encoders are used for more precise speed control in applications using these motors, and often times need to have more robust IP, shock and vibration parameters.
• Servo/Permanent Magnet Motors: These motors offer closed loop feedback control systems to applications that require higher precision and accuracy, and are not as robust as AC Induction motors. The motor encoder used on these motors can be modular, incremental or absolute depending on the level of resolution and accuracy required.
• Stepper Motor: These motors are cost effective, precise, and are typically used in open-loop systems. In systems using stepper motors where speed control is required, an incremental motor encoder is often mounted to this motor.
