Product Description:
The SE-B4.210.030-05.000 is a synchronous servo motor produced by Bosch Rexroth Indramat within the SE Synchronous Servo Motors series. It is intended for precise speed and position control in automated production lines where compact frame dimensions and sealed construction are required. In typical installations, the motor couples directly to ball-screw or belt drives, allowing the connected servo amplifier to regulate acceleration, velocity, and holding position without mechanical backlash. Its synchronous design provides controlled rotary motion for equipment that requires repeatable positioning under changing loads and operating speeds.
The mechanical interface has a flange measuring 142 × 142 mm, which aligns with standard machine frames. The pilot surface has a diameter of Ø130 j6 and a depth of 10 mm, while the housing seats in a mounting pilot bore measuring Ø125 H8. A center hole with a DIN 332-DS M8 thread accepts drawbar tooling. The solid shaft is ground to Ø24 k5 and projects 50 mm, allowing it to transmit torque through keyed or clamping couplings. Stator leads exit through a cable gland sized for 2.5 mm² conductors, and the unit has vibration grade N. The enclosure has an IP67 protection rating, permitting installation in areas that require washdown cleaning while protecting internal motor components from dust and temporary water immersion.
Airborne sound pressure remains below 58 dB(A) at rated load, helping limit motor noise during normal machine operation. The bearings are rated for 20,000 hours of operation under moderate thermal cycling. To support emergency stops and controlled deceleration, the optional plug-in brake can absorb 4085 Ws of kinetic energy and dissipate it through a 1.0 Ω resistance installed in the drive line. During impact loads, the housing tolerates peaks of 6 g, helping preserve alignment of the internal rotor-stator air gap. The motor is suitable for indexing tables, gantry axes, and vertical actuators that perform rapid cycles or require frequent holding events.
