Product Description:

The MSK101D-0450-NN-M1-BG2-NNNN is a synchronous servo motor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It is intended for precise torque and velocity regulation in industrial automation. In closed-loop systems, the motor converts drive current into controlled rotary motion for linear stages, rotary tables, and packaging axes that require accurate feedback. This makes it suitable for applications that depend on repeatable acceleration, steady speed control, and consistent positioning during frequent starts and stops.

Cooling is done through natural convection, so the housing must remain in unobstructed airflow during operation. Position feedback is transmitted over the Hiperface interface, which allows the connected drive to monitor motor position and motion in real time. The encoder generates 128 signal periods per revolution and uses an optical sensing principle for high resolution with minimal drift. For load holding or emergency stops, an electrically released brake supplies 70 Nm of static torque. Mechanical power is transferred through a plain shaft, which suits coupling arrangements used in applications that do not require a keyway. These features place feedback, braking, and cooling functions inside the motor assembly instead of relying on separate external components.

The stator uses winding code 0450, which matches the electrical characteristics expected by compatible MSK drive modules. The motor has a frame diameter of 101 mm and a D-length housing, giving it the physical size associated with this frame class. The encoder has multiturn absolute capability, so position data remain available after power loss and the axis can return to operation without a new homing cycle. A B-side power connector keeps the cabling on one face of the machine, which can simplify routing when installation space is limited. The standard design version also supports common series accessories such as right-angle plugs.
