The cyber^® power motor AF (with nature cooling) and AFW (with liquid cooling) are high-performance servomotors, which are characterized by very compact design, high torque density and wide speed range.
The modular design of cyber^® power motor support high level of modifications based on customer/application need. 
Compare nature cooled AF motor, the continuous torque and output power of AFW models are almost double, despite the sizing being almost as compact as AF series.
