Product Description:

The SF-B4.0230.030-00.030 is a servo motor produced by Bosch Rexroth Indramat within the SF Servo Motors series. As a permanent-magnet, three-phase unit, it delivers controlled rotary motion to automated packaging lines, pick-and-place modules, and indexing tables. The design couples to a servo drive that commands speed and torque, allowing repeatable position cycles under closed-loop feedback during frequent starts and stops. Its IM B5 flange arrangement permits direct mounting on gearboxes or machine frames, reducing alignment steps and helping keep the shaft centered during installation.

At a rated speed of 3000 rpm, the rotor reaches its continuous operating velocity, while locked-rotor torque reaches 22 Nm. Generating that output requires a phase current of 14 A, so the drive and motor cable must accommodate the corresponding thermal load. The electromagnetic design provides a torque constant of 1.57 Nm/A, creating a linear relationship between commanded current and developed torque across the working range. An enclosure rating of IP67 protects the stator against dust ingress and temporary immersion. Power reaches the motor through a size 1.5 circular connector linked to a cable containing four 4.0 mm² conductors, and the conductor set weighs 0.29 kg per meter. A keyway and feather key on the shaft transmit torque without slip and help maintain axial alignment during reversal cycles.

The drive train’s inertia budget is influenced by a rotor inertia of 54 × 10⁻⁴ kg·m², giving moderate acceleration without excessive current peaks. Operational sound pressure is limited to 58 dB(A), helping machines meet shop-floor noise targets in enclosed industrial production areas. Resistance to mechanical shock is verified up to 6 g, so the motor withstands handling impacts and short-duration vibrational loads during transport, setup, and operation.
