The Encoder Analyzer is the tester for checking encoders in electric motors. Modern motors are often equipped with rotary encoders. There is a huge variety of encoders, making checking complicated. This is especially valid for electric motor repair and production. This complex check is very difficult without special measuring technology. The Encoder Analyzer provides valuable services. It facilitates the encoder test by providing voltage to the rotary encoder and measuring and evaluating the signals. At the end the user receives clear GO or NO GO results.
