Miniaturized AC servomotor linear actuators are a type of rectilinear actuator which achieves high precision positioning as well as miniaturization and weight reduction. The motor portion utilizes a hollow AC servomotor, while the encoder portion utilizes a miniaturized and high resolution optical rotary encoder. Since its direct design does not utilize parts such as gears, this makes precise and high resolution positioning possible. In addition to the above characteristics, the MAB and MALB series utilize ball screws that allowed realization of high speed and long service life. Meanwhile, the MALS and MALB series feature models with superior cost performance, where large-scale cost reduction is achieved while maintaining high precision positioning. The multi-functional driver powering the AC servomotor linear actuator was developed exclusively for this purpose, and is both compact and lightweight. Since it possesses sine wave conductivity and low gain, it gives smooth operation and zero vibrations during positioning, which are features of utmost importance for a linear actuator. They can respond relatively easily to environments such as vacuums and clean rooms, meaning they can be used in a wide variety of fields. A few examples include industrial machinery (e.g. optical devices, semiconductors), measurement and test machinery.
