Product Description:

Bosch Rexroth Indramat builds the SE-B2.020.030-00.000 for position-controlled axes within the SE Synchronous Servo Motors series. This compact rotary unit converts electrical power into regulated torque for pick-and-place modules, indexing tables, and other industrial automation tasks where rapid cyclic motion is required. As a closed-loop servo element, it pairs with digital drives to furnish precise velocity and position feedback throughout the machine cycle. Its compact format suits installations that require quick reversal, repeatable positioning, and stable speed regulation in a limited mounting space.

The motor mounts against a machine frame with a square flange measuring 100 mm across, and its 14 × 30 mm keyed shaft transfers torque directly to couplings or gearheads. Under rated conditions, the rotor turns at 3000 rpm. At standstill, it draws 2.7 A and produces 2.9 Nm of holding torque, while short acceleration periods can use a peak current of 16 A. The torque constant is 1.10 Nm/A, which relates drive current to shaft output, and the rotor inertia is only 0.44 × 10^-3 kgm² for fast speed changes with limited overshoot. The winding resistance is 14.7 Ohm, which helps restrain copper losses during continuous operation.

The voltage constant is 114 V/1000 rpm, so the applied line-to-line voltage rises with motor speed. Phase inductance of 76 mH helps smooth current flow and reduce ripple in the control loop. The motor has a mass of 6.5 kg and an overall length of 230 mm, which helps when the axis must balance compact installation space with moving load limits. These electrical constants help the drive regulate current cleanly during both low-speed holding and higher-speed travel. The size and weight also fit servo-driven slides, rotary tables, and other mechanisms where compact packaging and predictable response are important.
