Product Description:
The MSK050B-0300-NN-M1-UP1-NNNN is a synchronous servo motor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It serves as an electromechanical actuator that delivers controlled torque and velocity to axes in automated assembly cells, pick-and-place gantries, and CNC auxiliary drives. Its standard mechanical layout, based on the 050 frame size and B length, allows installation in tight spaces while maintaining sufficient continuous power for mid-range motion duties in packaging, printing, and robotics equipment. This layout also supports dynamic positioning tasks that require stable response during repeated start-stop motion.
Its thermal design relies on natural convection, so heat leaves the housing through surface radiation without fans or liquid channels, an arrangement suited for cabinet-mounted motors where airflow is limited. The feedback assembly is fixed to a rotatable, 240° encoder connector that eases cable routing inside cramped enclosures. Position data travel through the Hiperface interface, allowing serial feedback transmission between the motor and drive. The optical scanning head resolves the scale into 128 signal periods, giving fine commutation information for smooth torque production. This accuracy comes from the optical sensing principle, which minimizes hysteresis compared with magnetic encoders. The connector arrangement also helps route the feedback cable more cleanly around nearby machine components.
For static holding on vertical axes, an electrically released brake is integrated; it clamps the shaft with 6 Nm of torque and releases automatically when current is applied. The brake works with the multiturn absolute encoder, enabling the drive to recover position after a power loss without a homing sequence. Mechanical output is delivered through a shaft with keyway, which simplifies coupling to pulleys or gearboxes. The compact 050 frame, B length, and winding code 0300 create a standard configuration that balances inertia and continuous torque while keeping installation weight low.
