Product Description:

The SF-L1.0023.060-00.000 is a brushless servo motor manufactured by Bosch Rexroth Indramat and belongs to the SF Servo Motors series. As a rotary actuator, it supplies controlled torque and speed for positioning axes in machine tools, pick-and-place modules, and packaging lines. The unit integrates a single-turn absolute encoder, allowing the drive controller to know the shaft position immediately after power-up, which shortens homing sequences and improves throughput in automated cells where repeatable startup behavior is important.

At a rated speed of 6000 rpm, the rotor can deliver continuous motion suitable for high-throughput stations. The electromagnetic design produces about 1 Nm of torque for every 1.5 A of phase current, and the torque constant of 0.69 Nm/A helps the drive estimate current demand during load changes. Position feedback is produced at 8 million increments per revolution, which supports very fine motion control together with the stated ±20-second accuracy figure. The housing is sealed to IP67, so the motor resists dust and temporary immersion in demanding machine environments. When the shaft is blocked, the motor can generate a locked-rotor torque of 2.3 Nm, and the phase current reaches 3.3 A under that condition for stall monitoring.

The motor also has compact mechanical proportions that suit fast-moving axes and tightly spaced machine layouts. The unit weighs only 2.6 kg, so it adds minimal reflected mass to moving assemblies and helps limit the load placed on slides or indexing tables. Rotor inertia is 1.20 × 10⁻⁴ kg·m², which allows rapid acceleration without excessive drive peak current during frequent start-stop cycles. The mounting pattern is IM B5, so the motor fastens by flange and aligns through a 60 mm pilot bore. The shaft size is Ø11 × 23 mm, allowing direct connection to compatible gearheads, couplings, or pulleys.
