Product Description:

The SF-L1.0008.060-10.000 is a servo motor manufactured by Bosch Rexroth Indramat for the SF Servo Motors series. It uses a permanent-magnet design to provide precise rotary motion for positioning stages, pick-and-place heads, and compact conveyor axes in automated equipment. When paired with a compatible drive controller, the motor closes the control loop through its integrated single-turn absolute encoder and provides immediate rotor-position feedback for repeatable motion. This type of motor is well suited to axes that require accurate starts, stops, and short positioning moves in a compact installation space. Its mechanical interface follows the IM B5 mounting form, so it can fasten directly to gearboxes or machine fixtures without added brackets.

At a rated speed of 6000 rpm, the motor can maintain synchronous operation while producing a continuous stall torque of 0.8 Nm. That output corresponds to a phase stall current of 1.1 A, which reflects the low current demand of this frame size. The torque constant of 0.73 Nm/A gives the controller a direct relationship between commanded current and delivered torque. This proportional behavior helps the drive regulate small torque changes smoothly during indexing and speed correction. Position feedback is supplied by a single-turn absolute STG encoder with a resolution of 8,000,000 incr/rev, which supports very fine position updates during rapid index moves. The feedback channel also allows the controller to track rotor angle continuously during both low-speed positioning and fast traverses.

Thermal management relies on natural convection, eliminating the need for forced air or liquid lines and helping keep the installation simple. Because no external cooling hardware is required, routing around the motor stays less crowded and there are fewer components near the axis. The same encoder provides an absolute accuracy of ±20 arcsec, which is suitable for tight registration tasks when used with a high-resolution drive. A compact 70 mm flange and an overall length of 182 mm keep the motor small, while the 2.5 kg mass helps reduce moving load on light axes. Rotor inertia of 0.47 × 10^-4 kg·m² supports quick acceleration and responsive motion control during frequent direction changes.
