Product Description:

The SF-A1.0012.060-10.050 is an AC servo motor manufactured by Bosch Rexroth Indramat as part of the SF Servo Motors series. In industrial automation, it drives low-inertia axes that require rapid speed changes while holding tight position tolerances, making it suitable for feeders, labeling heads, and miniature gantries. This type of motor is well suited to compact motion systems where short moves and repeatable stopping are important. Because it is intended for low-inertia applications, it can support frequent reversing and precise point-to-point motion in tightly spaced equipment. The unit mounts to machine plates in the IM B5 orientation, allowing quick integration into compact drive modules.

Its nominal operating point is 6000 rpm, a speed that permits fast indexing when coupled with suitably rated gearheads or direct-drive loads. The motor has a torque constant of 0.64 Nm/A, which helps the servo amplifier calculate current commands and regulate output predictably as load changes. A square frame measuring 70 mm on each side sets the mounting pitch for the face-mount housing. The mating surface carries an ingress rating of IP67, so internal bearings remain sealed during washdown or coolant splash. During startup, the motor may draw 1.9 A of locked-rotor current to overcome static friction and develop stall torque.

Without a brake, the motor weighs 1.9 kg and extends 207 mm from flange to end bell, reducing overhung load on small stage supports and helping preserve responsive axis behavior. That low mass is useful where the motor is mounted on moving carriages or other assemblies that must keep overall inertia low. Its rotor inertia of 0.63×10⁻⁴ kgm² lets the servo accelerate quickly while remaining stable in finely tuned velocity loops. The solid output journal measures 11 mm in diameter and 23 mm in length, providing enough engagement for clamp collars or keyed couplings while keeping windage low at high speed. The assembly withstands impacts up to 6 g and accepts a continuous axial thrust of 33 N on the shaft, enabling vertical mounting or preload springs without exceeding bearing limits.
