Overview
The Dunkermotoren BG65X75CI servo motor (SNR 88565-06706) is a brushless DC (BLDC) motor from Germany’s leading motion control specialist. Part of the BG 65 series, this unit delivers precise, smooth operation for industrial automation, positioning systems, and dynamic load applications. The integrated 4-quadrant controller variant enables seamless speed, torque, and position control without external amplifiers.
