Product Description:

The SF-L1.0012.060-04.058 is a compact synchronous servo motor produced by Bosch Rexroth Indramat within the SF Servo Motors series. It supplies continuous rotary output for axes that need fast positioning and repeatable speed control in packaging machines, pick-and-place modules, and similar equipment. By coupling directly to a gearbox or driven shaft, the motor helps reduce compliance in the power train and supports more precise motion transfer. Its compact form suits installations where mounting space is limited and cable routing must stay simple. Integrated feedback and brake circuits allow a compatible drive module to manage closed-loop velocity and torque control during dynamic machine operation.

During operation, the rotor can reach a maximum speed of 6000 rpm. The motor produces approximately 0.64 Nm/A, which allows drive current to be related directly to output torque. The matching power stage must provide 670 V on the DC link so the inverter has enough margin to maintain stable modulation as speed rises. A square 70 mm mounting flange supports accurate installation, and the output shaft is machined to Ø11 × 23 mm for compact couplings and small planetary gear sets. The keyway and feather key arrangement supports secure torque transmission and keeps the hub aligned during repeated reversals.

For holding and emergency stopping, the fail-safe brake provides 2.0 Nm of static torque and releases at a brake current of 0.4 A from a 24 VDC supply. At standstill, the stator can draw 1.9 A and resist with 1.2 Nm until motion resumes. The housing is sealed to IP67, which helps protect internal parts from dust and temporary water exposure when the shaft seal is maintained. Acoustic emission remains at or below 58 dB(A) at rated load, which helps keep machine noise low during normal use. The brake inertia of 0.12 × 10^-4 kg·m² adds only a small load to acceleration and deceleration.
