Product Description:

The SF-L1.0023.060-14.050 servo motor is produced by Bosch Rexroth Indramat as part of the SF Servo Motors series. It converts commanded electrical power into tightly regulated rotary motion for positioning and speed control duties in automated assembly cells, pick-and-place stations, and packaging equipment. The integrated spring-applied brake and sealed housing let the unit hold position after power loss while operating in washdown or dust-laden zones common to industrial automation. This arrangement is useful on axes that must remain stationary during an unplanned stop or while the main drive power is off.

The motor reaches a rated velocity of 6000 rpm, supporting short cycle times in high-throughput machines. A torque constant of 0.73 Nm/A provides linear torque production versus phase current, which helps the drive respond predictably during acceleration and low-speed control. At startup it can generate 2.3 Nm of locked-rotor torque to overcome static friction and begin motion smoothly. The brake coil is energized by a dedicated 24 VDC supply, keeping the brake circuit separate from the main power bus. An enclosure rating of IP67 prevents dust ingress and allows temporary immersion. The motor has a total length of 295 mm with the brake installed and uses IM B5 flange mounting for face attachment to machine structures. Its shaft measures Ø11 × 23 mm for coupling to the driven load. Brake power dissipation is 12 W, and the brake adds 0.38×10^-4 kg·m² of inertia to the rotating system.

The holding brake delivers 2.5 Nm of static torque so vertical or suspended loads remain stationary without external clamps. Bearing life is specified at 20000 h, which supports long operating periods in continuous-duty installations. Dynamic performance benefits from a rotor inertia of 1.3×10^-4 kg·m², limiting stored kinetic energy and helping the axis change speed quickly while the drive draws only 3.16 A during stall conditions. Lower inertia also helps reduce overshoot when the motor reverses direction frequently. Mechanical durability is confirmed by a shock resistance of 6 g, enabling use on mobile frameworks and vibration-intensive processes without loss of function. These characteristics suit applications that combine rapid motion, frequent stops, and steady holding behavior.
