Beckhoff Automation (Burnsville, MN) has released the AM8000 servo motor series featuring single-cable technology that combines the power and feedback system into one standard motor cable. The encoder data, rotor position, multi-turn information, and status of the thermal conditions in the motor are transmitted via a digital interface. The series consists of six different motor sizes, each with two or three optional overall lengths. Users can select from a stall torque range of 0.9 to 65 Nm. Salient pole winding technology is used in the rotor, which enables a higher slot fill factor. Small end turns, in conjunction with a fully encapsulated stator, provide thermal management.
