In 1960s, Yaskawa Electric had produced distinctive DC servo motors one after another and came to commercialize AC servo motors in 1983 while making a new trend in the motor industry. Now, after more than thirty years, almost 100% operators in factory automation industry apply AC servo motors. Yaskawa’s industrial robots also apply AC servo motors manufactured in-house for their joints.
Motors in general aim to work by rotating load continuously, however, servo motors also aim to respond to the target precisely and swiftly. By the way, do you know what “servo” means? The origin of the word is “servus” in Latin (or “slave” in English). Slaves obey the masters’ command and do as they are told. People started to use the word “servo” as it aims to control the target’s location, speed and route as it intended to.
