In order to provide highly dynamic servo motor technology to a wider range of applications, Beckhoff Automation (Savage, MN) has released the new AM8500 series of servo motors. With an increased rotor moment of inertia, this advanced servo solution extends the performance range of Beckhoff servo motors.
The AM8500 servo motor series is suitable for all applications with larger external mass inertias, in particular CNC applications in machine tools and woodworking machines. Typical applications for the AM8500 servo motors also include printing machines, film winders, and feeding drive units. The AM8500 series features:
- A wide performance range with four sizes and three lengths with standstill torques from 1.38 to 29 Nm.
- One Cable Technology (OCT), with which the power and feedback systems are combined into one standard motor cable.
- Special internal electromagnetic design for excellent overload behavior.
With the increased rotor moment of inertia, the new AM8500 series now provides further benefits for applications with demands for large loads and high synchronism. Due to the modified rotor geometry, the moment of inertia is increased, depending on the length, by 100 to 300% compared to previous AM8000 series servo motors.
As a result of the high rotor inertia, the control of the AM8500 is simplified in areas where a high external inertia must be moved, because the servo motors tend to vibrate less and can be adjusted much more easily by the servo controller. In some cases it is even possible to do without a gearbox if one is otherwise necessary only for the ratio of external to intrinsic inertia.
