# 【TBL-i mini Series】 Miniature AC Servo Motors

A miniature AC servo motor, measuring 14.5,19.5,22mm, has been added to our lineup-making possible via densification the size reduction of products such as semiconductor fabrication equipment, chip mounters, and small XY tables. In order to integrate with a variety of sensors, this AC servo motor is available as either an encoder or resolver.
