The Bosch Rexroth Indramat MSK071E-0450-NN-M1-BG1-NNAN from the MSK IndraDyn S Synchronous Motors series is a high-precision Product Type designed for demanding servo applications. This motor features a compact Motor Size 071 frame combined with a Motor Length E design, achieving a balance of torque density and installation flexibility. Equipped for a Rated Speed Code 0450, it delivers smooth dynamic response across its operating range. Passive thermal management is provided by Cooling Natural convection, ensuring reliable operation without auxiliary fans.
Electrical performance is a standout feature: the motor sustains a Continuous Current at Standstill 100 K of 24.4 A and a Continuous Torque at Standstill 100 K of 28.0 Nm for extended holding duties. In peak-demand scenarios, it can handle up to Maximum Current 90.1 A and generate a Maximum Torque of 84.0 Nm. The robust Winding Inductivity 2,600 mH contributes to low ripple current and exceptional current smoothing. Connectivity is seamless via the Power Connector B-Side, while the integrated optical Encoder Technology delivers precise positioning through a Multiturn Absolute Encoder Turn Type with Encoder Resolution of 128 signal periods. Communication is handled by the proven Encoder Interface Hiperface, enabling high-bandwidth feedback and minimal latency.
Mechanically, the motor incorporates a Shaft Type Plain shaft that suits a variety of coupling options and gearboxes. An electromechanical safety feature is provided by the integrated Holding Brake with holding brake, electrically-released, which supplies a Holding Brake Torque of 23 Nm for secure load retention when de-energized. The rugged design supports precise motion control in robotics, pick-and-place systems, and high-inertia drive trains. Simplified mounting and consistent performance characteristics make this MSK motor an ideal choice for OEMs pursuing compact, reliable, and high-torque servo solutions.
