Product Description:

The SF-L1.0016.060-04.050 is a servo motor produced by Bosch Rexroth Indramat for the SF Servo Motors series. It combines a permanent-magnet rotor with an integrated electromagnetic brake so the shaft can remain in position when power is removed. Within industrial automation, the unit supplies tightly regulated torque and speed to indexing tables, small actuators, or feeder mechanisms that require repeatable motion profiles. The integrated brake also helps prevent unwanted axis movement during power loss or controlled stops, which is useful on compact machines with frequent start-stop cycles.

The brake circuit is energized at 24 V DC, drawing 12 W to hold the armature off the friction disk during normal operation. When commanded, the disk seats in 30 ms. Release requires only 20 ms, helping reduce delay during repeated cycling. Static holding capacity is rated at 2.5 Nm, so the brake can hold the shaft securely when the motor is not being driven. Under power, the windings accept a standstill current of 2.2 Arms, providing the magnetic flux needed for rated stall duty without excessive heating. Dynamic operation is supported by a maximum mechanical speed of 6000 rpm, while rotor position remains stable because the brake adds controlled inertia to the rotating assembly.

The electromagnetic section produces 1.6 Nm at zero speed, and each additional ampere raises torque by 0.73 Nm/A, which helps match the motor to a compatible drive amplifier. A housing diameter of 75 mm and a pilot diameter of 60 mm with a j6 tolerance support accurate alignment with compact gearheads. The keyed shaft measures 11 mm with a k6 tolerance, allowing direct coupling to pulleys or couplings with controlled fit. Total assembly length with the brake installed reaches 269 mm, yet the combined rotor and brake inertia remains low enough for responsive acceleration. The brake mass is included in the rotating system data so motion profiles can be checked against available drive current during axis setup.
