Product Description:

The SF-A3.0093.030-00.000 is a permanent-magnet, brushless servo motor manufactured by Bosch Rexroth Indramat within the SF Servo Motors series. It is designed for synchronous operation with an electronic drive. The unit converts commanded current into precise torque and velocity, allowing automated machinery to index, follow profiles, or hold position under closed-loop control in assembly cells, packaging lines, and material-handling systems.

At its rated operating point, the rotor can spin at 3000 rpm, a speed that matches transmission ratios used in factory automation. The electromagnetic design supplies 1.35 Nm/A of torque per ampere, giving the controller a predictable relationship between phase current and mechanical output. During start-up or stall events, the motor can deliver a locked-rotor torque of 8.1 Nm while drawing 6.0 A. Dynamic behavior is also influenced by a rotor moment of 16 × 10⁻⁴ kg·m², which supports a balance between fast acceleration and smooth running. Its 287 mm length keeps the motor compact enough for space-limited installations, and two integrated NTC sensors send winding temperature data to the drive so current limits can be adjusted in real time.

A B5 flange with a diameter of 116 mm centers the housing, while the keyed shaft measures Ø19 × 40 mm and transmits torque into gears or couplings with minimal play. The bearing set tolerates an axial load of up to 133 N, allowing moderate thrust from helical gears or belt tensioners. Position feedback is provided by a single-turn absolute encoder that reports 8 million increments per revolution, enabling fine interpolation for high-resolution servo loops after every power cycle. The motor follows IM B5 construction, which places the mounting flange on the drive-end face for footless attachment to a gearbox or machine frame.
