Product Description:

The MSK030B-0900-NN-M3-UG0-NNNN synchronous servo motor is part of the MSK IndraDyn S Synchronous Motors series from Bosch Rexroth Indramat. It is built to deliver closed-loop torque and velocity control to positioning axes, pick-and-place gantries, and other automated machinery that rely on precise electrical actuation. By combining a permanent-magnet rotor with compact stator windings, this motor converts electrical energy from a drive controller into mechanical rotation with tight following error, making it suitable for high-accuracy industrial automation tasks. The rotor and stator arrangement helps the axis respond quickly to commanded current changes during acceleration, deceleration, and steady-speed operation.

Thermal management is handled by natural convection, so the housing dissipates heat into ambient air without external fans, which is useful in cabinets with limited airflow. The motor uses a standard mechanical design and a B-length housing to balance torque output with overall depth. Position feedback is provided by a capacitive measuring system connected through the Hiperface interface, and this combination supplies absolute position data while resisting magnetic interference. To simplify wiring in tight spaces, the encoder plug is rotatable through 240°, allowing the cable to exit in multiple directions and helping reduce sharp bends near the housing. Internal signal processing divides one electrical revolution into 16 signal periods, giving finer interpolation when paired with the drive.

The motor is supplied without a holding brake, and its feedback device tracks multiple turns as a multiturn absolute encoder, so position remains valid after power cycles. The output shaft is a plain shaft, which facilitates direct coupling with precision clamping hubs or gears where backlash must be minimized. That shaft style is commonly used where torque is transferred through friction-locked couplings instead of keyed connections. The motor uses winding code 0900, matched to drives that can supply the needed current and voltage window, and the compact frame size of 030 reduces inertia for rapid acceleration.
