Product Description:

The SF-A2.0013.060-14.037 is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the SF Servo Motors series. It converts electrical energy from a matched drive into controlled mechanical rotation for positioning and velocity control in automated machinery, such as pick-and-place modules or spindle stations. By combining an integral holding brake with a high base speed, the unit supports rapid start-stop cycles while retaining position when power is removed, making it suitable for axis groups that demand light clamping and repeatable accuracy.

At its rated operating point, the motor reaches 6000 rpm, a speed that allows direct coupling to small transmission ratios for fast traverse moves. A torque constant of 0.76 Nm/A links drive current to developed torque, simplifying current-loop tuning. The shaft can accept up to 70 N of axial load, so light thrust from preload springs or vertical orientations is permissible. When the brake is energized, it draws 0.56 A, a current level easily supplied by common auxiliary circuits. During continuous service, the sound pressure remains below 58 dB(A), supporting installation close to operators. The electrical side is fed from a 670 VDC link, allowing high power density without oversizing the conductor cross-section.

The electromagnetic holding device engages at 24 VDC, delivering 3.2 Nm of static torque to keep the load stationary when power is removed. Its inertia contribution is limited to 0.4 × 10⁻⁴ kg·m² and the brake mass is only 0.35 kg, so the added rotating mass has minimal impact on acceleration times. For startup calculations, the drive must withstand a locked-rotor current of 1.7 A that corresponds to a stall torque of 1.3 Nm. Once running, the assembly tolerates shocks up to 6 g, allowing installation on tooling frames that experience momentary impact or rapid index stops.
