Product Description:

The MSK040B-0450-NN-S1-UG0-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. This motor acts as a compact drive element in automation cells, translating controller current commands into precise torque and speed for positioning tables, pick-and-place gantries, or light machining axes. It is intended for installation in compact machine spaces where short axis travel and quick direction changes are common. Its electromagnetic design uses a standard configuration for general industrial motion tasks.

Heat generated in the stator is removed by natural convection, eliminating the need for fans or coolant circuits and simplifying the machine layout. The feedback device employs optical scanning, and its electrical interface follows the Hiperface protocol, allowing position data and supply power to pass through a single cable. Within the encoder housing, the plug is rotatable through 240° to ease cable routing in crowded cabinets and around nearby machine components. The internal code disk produces 128 signal periods per mechanical revolution, providing raw resolution that supports fine interpolation by compatible IndraDrive controllers during contouring moves.

The mechanical output conforms to a plain shaft profile, so torque must be transferred by a clamp or hub without relying on a keyway. The motor is supplied without a holding brake, so static load retention must be managed by the drive or an external locking device. A compact stator with winding code 0450 pairs with frame size 040, delivering moderate continuous torque while keeping rotor inertia low for agile acceleration. Overall length category B reduces installation depth in machines with restricted space. Because the encoder is a single-turn device, it reports absolute position within one revolution and requires controller counting for multi-turn tracking.
