Product Description:

The SF-L1.0008.060-14.000 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the SF Servo Motors series. Intended for industrial automation, it provides closed-loop rotary motion so controllers can manage acceleration, velocity, and positioning tasks on assembly tables, packaging stations, or pick-and-place lines. By converting drive current into precisely regulated torque, the unit allows machines to execute incremental moves, maintain constant speed, or follow motion profiles required for repeatable production cycles. This supports accurate starts and stops in applications that depend on consistent axis response.

The motor mounts through a square flange that measures 70 mm, and its smooth 11 mm by 23 mm shaft simplifies coupling to gearboxes or direct-drive loads. This shaft format also suits compact couplings where axial space is limited and a keyed connection is not required. Including the integrated brake, the overall length is 219 mm, which helps fit the motor into tight machine layouts. Under nominal conditions, it reaches 6000 rpm, while a torque constant of 0.73 Nm/A links commanded current to output torque. At zero speed, the winding draws 1.1 A, and a locked-rotor torque of 0.8 Nm sets the stall boundary for safe controller tuning. The housing is rated to IP67, which keeps out dust and withstands limited water immersion during washdown procedures.

Static load retention is provided by an electromagnetic brake that supplies 2.5 Nm of holding torque. The brake coil operates from 24 VDC, consumes 12 W, and adds only 0.38 × 10⁻⁴ kg·m² of inertia, complementing the rotor’s own 0.47 × 10⁻⁴ kg·m² value so acceleration response remains sharp. Position feedback comes from an STG incremental encoder with 8 million increments per revolution, allowing the drive to detect very small angular changes and reduce following error during fine positioning. High feedback resolution also helps the axis correct small position deviations during low-speed motion and short indexing moves.
