Product Description:
The SE-B3.055.030-10.037 is a synchronous servo motor produced by Bosch Rexroth Indramat within the SE Synchronous Servo Motors series. Designed for closed-loop axis control in industrial automation, it converts precise electrical commands into controlled rotary motion for packaging stations, handling axes, and positioning tables that require repeatable speed and position control. Its mechanical design follows the IM B5 mounting orientation, so the unit bolts directly to machine frames, and a brushless tachogenerator provides speed feedback to the drive controller for stable regulation.
The motor is sealed to IP67, so dust and sprayed liquids cannot reach the internal windings during washdown duty, and the housing can withstand brief immersion. A flange pilot diameter of 110 mm aligns the stator concentrically to gearboxes, and the centering hole is threaded M6 for draw-bar extraction. Under continuous operation, the rotor maintains a nominal speed of 3000 rpm. The motor produces a standstill torque of 12.6 Nm. Acoustic emissions remain at or below 58 dB(A). Supplementary shock resistance of 6 g protects the magnet assemblies during transport, and the 116 mm square flange helps distribute radial loads evenly.
Electrical connection is made through a dedicated power lead designed for a conductor cross-section of 2.5 mm², which keeps copper losses low while matching common servo drive terminals. The bearing set can support a permissible axial thrust of 145 N, allowing the motor to handle ball-screw preload without premature wear. Output torque is delivered by a keyed shaft that measures 19 mm in diameter and extends 40 mm beyond the flange, providing adequate engagement length for rigid couplings. This shaft arrangement also supports secure mounting of standard hubs during installation.
