The Bosch Rexroth Indramat MSK040B-0450-NN-M1-UP1-NNNN from the MSK IndraDyn S Synchronous Motors series is a precision-engineered IndraDyn S Synchronous Servomotor designed for dynamic motion control. This standard design motor combines a compact Motor Size 040 envelope with a versatile Motor Length B profile for easy integration into existing machine architectures. Equipped with a robust Shaft Type: Shaft with keyway, it ensures secure coupling to gearboxes or pulleys. With a built-in electrically released Holding Brake offering 4 Nm of torque, it secures loads in stationary applications without external braking systems.
Incorporating natural convection cooling, the MSK040B-0450-NN-M1-UP1-NNNN maintains optimal thermal performance across extended duty cycles. The servo motor achieves a Rated Speed Code 0450 and delivers a Maximum Torque of 5.1 Nm while drawing up to Maximum Current of 6.0 A. At a standstill and 100 K, it sustains a Continuous Torque of 1.9 Nm with a Continuous Current of 1.7 A, enabling precise holding and low-speed positioning. Its high-inductance winding at 64,700 mH smooths current ripple for refined torque output and low acoustic noise.
Position feedback is handled by an optical multiturn absolute encoder with a rotatable, 240° Encoder Connector and Hiperface interface, yielding 128 signal periods per revolution for sub-micron resolution. This combination of advanced encoder technology and durable mechanical construction simplifies commissioning and in-field replacement. Engineered for reliability and ease of use, the motor's sealed frame and conformal coating resist industrial contaminants.
Robust braking integration and plug-and-play encoder connectivity streamline system assembly, reducing cabinet space and wiring complexity. The high-inductance design ensures stable operation under variable loads, and the absence of auxiliary cooling fans improves mean time between failures. Ideal for robotics, packaging machines, and assembly lines, the MSK040B-0450-NN-M1-UP1-NNNN delivers consistent performance and dependable uptime in demanding automation environments.
