Product Description:

The SF-L1.0012.060-04.050 servo motor is manufactured by Bosch Rexroth Indramat as part of the SF Servo Motors series. It serves as an electromechanical actuator that converts drive current into precise rotary motion for tool heads, indexing tables, and compact transfer modules on automated production lines. Compact flange dimensions and an integrated holding brake allow the motor to fit into tight machine frames while still providing the fast dynamic response needed for cyclic positioning tasks.

With a torque constant of 0.64 Nm/A, each ampere delivered by the servo drive translates into proportional output torque, and the rotor sustains a continuous rated speed of 6000 rpm for high-throughput motion loops. The flange dimension of 70 mm matches standard ISO size interfaces and simplifies direct mounting to gear stages. During stall diagnostics, the stator can accept a locked-rotor torque of 1.2 Nm while drawing a locked-rotor current of 1.9 A without exceeding thermal limits. Free-running sound pressure reaches 58 dB(A), and the assembly withstands 6 g shocks so that vibration from adjacent equipment does not disturb encoder accuracy.

The servo’s regenerative channel is matched to a DC bus nominal of 670 V, allowing common bus operation with high-power converters. An integral spring-applied brake supplies a holding torque of 2.0 Nm at a release voltage of 24 VDC and draws only 0.4 A, limiting standby power. The brake adds 0.12 × 10⁻⁴ kg·m² of inertia to the shaft, which keeps acceleration targets attainable. Two NTC temperature sensors embedded in the stator windings transmit real-time thermal data to the drive controller. The housing follows the mounting orientation code IM B5, so the motor can be fixed on its flange with the shaft extending horizontally or vertically without additional brackets.
