Servomotor series with water cooling
AM8300 servomotors achieve an extremely high power density due to their water cooling system, allowing them to deliver up to 40 kW of rated power. The servomotors also offer maximum dynamics, as the moment of inertia remains constant but much higher currents are possible with water cooling. This also results in a threefold increase in the standstill torque. In terms of technology, the AM8300 series is based on the AM8000 series and its options. Five flange sizes, each with three lengths and standstill torques from 5.1 to 274 Nm, cover a wide range of applications. The water cooling system and high IP65 protection rating of the AM8300 make it particularly suitable for high ambient temperatures.
The advantages of water-cooled motors at a glance:
- high power range with rated power of up to 40 kW
- standstill torques increased significantly (up to 3x that of convection cooling)
- maximum power density
- combination of high rated torque and low moment of inertia assures maximum dynamism
- cooling enables use at critical ambient temperatures
- modular principle with all options as included for the AM8000 servomotors
