Product Description:
The SE-B2.020.030-00.003 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the SE Synchronous Servo Motors series. In automated machinery, the unit transforms drive inverter output into controlled shaft rotation, allowing accurate velocity and position regulation on packaging lines, pick-and-place arms, and indexing tables. Rotary power is transmitted through a shaft machined to Ø14 k5, and the flange follows the IM B5 construction so the motor can be face-mounted to gearboxes or couplers.
During locked-rotor operation, the phase windings require 2.7 A of standstill current, which helps the drive calculate heat rise and set stall protection. An enclosure rating of IP67 seals the housing against dust and temporary immersion, supporting washdown installations. The overall length is limited to 230 mm, simplifying cabinet or gantry layouts, while airborne acoustic output does not exceed 58 dB(A), keeping sound pressure within typical factory limits. The centering diameter is Ø95 j6, and a DIN 332-DS M5 centering hole is provided for accurate seating. Power conductors with an area of 1.5 mm² connect to the stator. The tacho generator supplies 2.7 V per 1,000 rpm for analog feedback.
The motor has a mass of 6.5 kg, permitting manual handling while providing enough thermal mass for moderate duty cycles. It withstands shocks up to 6 g, so transport and gantry impacts do not disturb internal alignment. The bearings have a minimum service life of 20,000 hours, which matches common maintenance intervals for equipment that runs continuously. Internal electronics accept a sensor supply of ±15 V DC, allowing standard drive interfaces to power the tacho and optional encoders. A feather key measuring A5 × 5 × 25 provides positive torque transfer between the shaft and the connected component. The motor windings exit through a radial connector sized for the stated conductor area.
