According to Beckoff, the AM3500 series of servo motors have a high moment of inertia, making them well suited for machine tool axes with stringent synchronism requirements. Beckoff claims these motors can eliminate a gear box in high inertia applications such as rotary tables. The new models are available with flange sizes 3 to 6, torques between 1.9 and 15 Nm and rated speeds of 3,000 and 6,000 rpm. Resolvers or absolute encoders (single- or multi-turn) are available as a feedback system. The standard protection class is IP 64 with IP 65/67 available as an option. This motor series is CE-, UL- and CSA-listed.
