Product Description:
The SE-B4.170.030-05.000 is a synchronous servo motor built by Bosch Rexroth Indramat for the SE Synchronous Servo Motors series. It converts drive commands into precise rotary motion for positioning tables, packaging stations, and other industrial automation axes. The motor integrates with digital drives that regulate current and velocity, supplying closed-loop torque so machinery can accelerate, hold, and reverse loads with high repeatability. This control method allows the connected drive to correct motion errors as operating loads change.
A 142 mm flange fits IEC gearheads, while the 130 mm centering diameter and M8 mounting hole align the motor concentrically with the machine frame. The housing has an IM B5 mounting arrangement that supports face mounting without feet. The motor produces a maximum torque of 43.0 Nm, providing peak twisting force during acceleration. Continuous operation occurs near the nominal speed of 3000 rpm, allowing direct coupling to medium-inertia loads. The enclosure has a protection class of IP67, preventing dust ingress and protecting the motor during temporary immersion. A shaft with a diameter of 24 mm and a keyed length of 50 mm transmits power to the connected equipment. The control and power leads exit through a motor connector that accepts conductors measuring 2.5 mm². Internal tachogenerator feedback maintains speed ripple within 1.5% for stable regulation.
The motor provides a static torque of 17 Nm, which helps prevent drift when a vertical axis is held by drive current. The bearings have a service life of 20,000 hours, supporting extended production schedules between planned overhauls. The rotor and stator assembly tolerates mechanical shocks of up to 6 g, helping the unit remain aligned when installed on fast-indexing stations. Acoustic emissions measure 58 dB(A) during rated rotation, keeping sound pressure within typical factory limits. Proper shaft alignment and secure flange mounting help prevent excessive bearing loads during operation. The keyed shaft provides positive engagement with compatible couplings, while the sealed enclosure protects internal components in dusty or wet operating areas.
