Product Description:

The SF-A5.0460.030-00.000 is a synchronous servo motor produced by Bosch Rexroth Indramat for the SF Servo Motors series. Designed for integration with digital drives, it supplies precisely regulated torque and velocity for pick-and-place heads, feed rolls, and other motion axes in automated production lines. In automated machinery, it converts electrical input into controlled rotary motion for axes that must maintain accurate position under changing loads. Its closed-loop operation supports repeatable motion where quick response and stable speed control are required during frequent starts, stops, and direction changes.

At a rated speed of 3000 rpm, the motor reaches its nominal mechanical output, while the connected converter furnishes a DC link of 670 V to the stator windings. When the shaft is held, it can develop 46 Nm of locked-rotor torque by drawing 29 A rms, which supports static holding or startup under heavy load. The electromagnetic relationship is characterized by a torque constant of 1.58 Nm/A, so commanded current translates into predictable torque. A flange diameter of Ø180 j6 aligns the frame to standard gearboxes, and the shaft is machined to Ø32 k5 × 58 mm for rigid coupling. The mechanical length is 383 mm, and the motor includes an A10 × 8 × 50 feather key. These dimensions, together with a rotor inertia of 166 × 10⁻⁴ kg·m², influence the system’s acceleration profile during dynamic motion.

Feedback is provided by a single-turn absolute STG encoder with 8 million incr./rev. of resolution and an accuracy of ±20 angular sec, enabling tight position loops without external sensors. This feedback system allows the drive to maintain stable control during both positioning moves and continuous-speed operation. When paired with the correct mating connector, the housing achieves IP67 ingress protection, which helps block dust and supports washdown exposure. Total mass is 35 kg, adding stability during mounting and operation. The keyed shaft arrangement is suitable for applications where coolant splash, airborne particulates, and frequent restarts are common.
