The AM8300 servomotors expand this company’s portfolio to include a modular motor series with integrated water cooling (photo). Due to the efficient cooling, an extremely high power density is achieved, so that a rated power of up to 40 kW can be delivered in the smallest installation space, depending on the size. Compared to similar conventional convection-cooled motors, the standstill torque is three times higher, the company says. The servomotors offer maximum dynamics, because the torque increases with water cooling, but the rotor moment of inertia remains constant. These are particularly suitable for applications with higher speed and torque requirements. — Beckhoff Automation GmbH & Co. KG, Verl, Germany
