Product Description:

The MSK040B-0450-NN-S2-UG0-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It delivers controlled torque and speed to automated axes, enabling repeatable positioning in pick-and-place heads, compact gantries, and packaging machinery. An optical encoder integrated at the rear of the housing supplies real-time rotor feedback so the associated drive can close its control loop without separate measuring devices. This arrangement helps reduce component count on compact machines where installation space and cable routing must remain efficient.

This motor disperses heat to ambient air through natural convection, eliminating the need for forced cooling hardware and keeping the overall size minimal. Its enclosure is sealed to IP65, so internal windings and bearings remain protected against airborne dust and water jets common in plant environments. The feedback connector can be rotated through 240°, allowing the cable outlet to be aligned with cabinet routing while maintaining strain relief. Position data are transferred over the EnDat2.1 serial interface, and the optical measuring system resolves motion into 2048 signal periods per mechanical revolution, giving the controller fine interpolation capability. Because the motor is supplied without a holding brake, applications that require power-off locking must use an external clamp or rely on drive torque.

A single optical track encodes the shaft angle as a single-turn value, so absolute position is maintained over one revolution without counting wraps. Continuous operation is specified between 0–40 °C, and the drive should apply derating if the surrounding air rises above that range. Output torque is transmitted through a plain shaft, making it suitable for clamp or shrink-fit couplings that avoid keyway stress concentrations. This shaft style is commonly used where the driven element is secured by friction instead of a keyed connection. The electromagnetic design identified by winding code 0450 pairs with B length and 040 frame size to support dynamic torque with low rotor inertia for high-speed indexing duties.
