Product Description:

The MSK040B-0450-NN-S1-UG0-NSNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. Designed for closed-loop motion tasks, the unit converts drive current into precise torque and speed for positioning tables, pick-and-place heads, and light gantry axes in automated assembly and packaging lines. Its compact frame helps reduce machine footprint, and the integrated feedback interface supports the repeatable motion needed for short cycle times. This motor is suited to applications where accurate positioning, stable speed control, and compact installation are all important.

Thermal management relies on natural convection, so heat leaves the housing without fans or external air-handling components. The motor size code 040 indicates the compact frame used for this model, which helps keep rotating mass low for responsive acceleration and deceleration. Winding code 0450 identifies the electrical winding used for this motor, matching it to compatible IndraDrive amplifiers and the expected operating characteristics of the drive system. Position feedback is handled through a Hiperface optical system with 128 signal periods, allowing the controller to interpolate fine position increments for accurate motion control. Length code B gives the motor a moderate stack length, and the unit is supplied without a holding brake, making it suitable for axes where load retention is handled by the machine or drive system.

The feedback connector is rotatable through 240°, allowing the cable outlet to be positioned for available space and cleaner routing. Because the encoder is a single-turn device, it reports absolute position within one mechanical revolution, which suits rotary axes that return to a reference point during normal operation. A plain shaft supports direct clamping with backlash-free couplings and avoids the need for a keyed connection in many compact servo applications. The mechanical construction uses a standard design with explosion protection, making the motor suitable for installations that require this type of protective arrangement when paired with the correct surrounding components. These features support straightforward integration into compact motion systems where cable orientation, shaft coupling, and feedback behavior must fit within limited installation space.
