Product Description:

The SD-B 3.050.030-05 is a brushless servo motor produced by Bosch Rexroth Indramat as part of the SD Magnet Motors series. The unit converts commanded current into controlled rotary motion, allowing precise positioning and velocity control in automated lines, pick-and-place stations, and material-handling gantries where rapid reversals and repeatable cycles are critical to product throughput.

The motor mounts to machinery through a 116 mm flange and reaches a nominal speed of 3000 rpm, giving integrators a standard mechanical interface and a moderate base velocity for gearless coupling. Its peak demand reaches 21.2 A, while a standstill torque of 5.0 Nm maintains load position without motion. The ferrite magnet rotor works with a phase winding inductance of 18.0 mH to smooth current transitions, and the 2.58 Ω winding resistance limits thermal rise under continuous operation. For feedback, the built-in tachogenerator produces 2.7 V per 1000 rpm and must see at least 20 kΩ input resistance for proper loading. At rest it draws 5.3 A, and acoustic emissions stay at 64 dB(A), permitting installation near operators in standard factory environments.

Environmental and dynamic limits further define application suitability. The housing carries an IP54 rating that blocks harmful dust ingress and water splashes, and safe ambient temperature spans 0 – 40 °C without derating. A torque constant of 0.94 Nm/A links commanded current to delivered shaft torque, while the voltage constant of 131 V/1000 rpm sets back-EMF expectations for drive sizing. The rotor inertia of 2.90 × 10⁻³ kg·m² provides a compromise between fast acceleration and load stability, ensuring responsive yet predictable behavior in indexing or short-stroke motion profiles.
