Product Description:
Bosch Rexroth Indramat builds the SE-B4.210.015-00.014 for its SE Synchronous Servo Motors series. This three-phase servo motor provides closed-loop rotary positioning for packaging machines, gantry axes, and similar automation where repeatable motion is critical. An integrated commutation sensor aligns the electronic drive with the rotor magnets, while a brushless tachogenerator supplies speed feedback. This combination lets the controller adjust current in real time and maintain stable motion during acceleration, deceleration, and steady-speed operation. Because the feedback devices are built into the motor, external sensing hardware is not required at the shaft end, which helps keep the installation compact.
The motor mounts through a 130 mm centering diameter, giving concentric alignment between the flange and the machine frame. Its IM B5 construction means the housing is face mounted, so radial forces stay close to the bearing set. Heat is removed by radiation and natural convection, eliminating fans and helping keep the housing simple in dusty areas. A 142 mm flange size matches many IEC gearheads, and the housing has an IP67 rating that blocks dust ingress and withstands temporary immersion. An integrated thermistor monitors winding temperature during operation, and vibration grade N helps keep running behavior smooth over a wide speed range.
Acoustic emissions stay below 58 dB(A), which supports quieter operation when the axis is installed near personnel. The rated mechanical design targets a minimum service life of 20,000 h under proper load and ambient conditions. Up to 154 N of axial thrust can be applied without exceeding bearing limits, which is useful for belt tension or helical gear meshes. A 24 mm shaft diameter paired with a 50 mm shaft length provides enough surface for couplings while maintaining torsional stiffness. The motor also tolerates transport shock up to 6 g, helping protect internal components during handling and installation.
