Product Description:

The SF-L1.0012.060-10.000 is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the SF Servo Motors series. It operates as a rotary actuator for machine tools, packaging lines, and material-handling stations where rapid indexing and precise speed control are required. When connected to a digital drive controller, the motor supplies closed-loop torque and velocity so motion sequences remain coordinated with PLC commands. This type of motor is commonly used on feed axes and transfer mechanisms that need steady control during repeated starts, stops, and direction changes. Its compact format suits light-to-medium duty axes that must accelerate quickly without taking up much machine space.

The motor uses a flange that measures 70 mm, allowing it to bolt to compact gearboxes or directly to machine frames while maintaining alignment. During operation, its windings support a rated speed of 6000 rpm, and the magnetic design gives a torque constant of 0.64 Nm/A so the drive can relate phase current to output torque. Under stall conditions, the phase demand rises to 1.9 A, and the shaft can hold 1.2 Nm without rotation. An STG multi-turn encoder supports closed-loop control and reports position through 1 Vpp signals. The encoder feedback lets the drive maintain position tracking even at low speed, where open-loop operation would be less stable. The smooth 11 x 23 mm shaft simplifies coupling with low-backlash clamps, and two onboard NTC sensors send temperature data to the inverter for monitored operation.

Feedback resolution is supported by an incremental scale that delivers 8 million increments per revolution, giving the controller very fine position data for indexing moves. Dynamic response is aided by a rotor inertia of 6.3 × 10⁻⁵ kg·m², which helps limit overshoot when the axis is driven through frequent reversals. The housing length of 207 mm helps the motor fit in crowded installations, and the assembled unit weighs 1.9 kg, which reduces the load on linear slides or robot wrists that carry the motor. The short housing also leaves more room for connectors and cable bends in tight machine layouts. Because the moving mass stays low, the motor is also suitable for carriage-mounted applications where excess weight can reduce acceleration and increase vibration during cycle changes.
