Product Description:

The SF-L1.0023.060-04.050 belongs to the SF Servo Motors series produced by Bosch Rexroth Indramat. Intended for closed-loop motion axes in automated machinery, the motor supplies controllable rotary power for indexing tables, pick-and-place heads, and feed rollers. Its keyed output shaft with a feather key simplifies coupling to driven components, which helps prevent slip between the motor and the driven load. The compact frame fits standard machine spaces, and the motor is suited to light assembly and material-handling equipment where quick starts, stops, and repeatable positioning are required throughout normal operation.

A permanent-magnet brake is integrated for load holding when the axis must remain in place. It is energized at 24 V DC, draws a steady brake current of 0.4 A, and can resist back-drive with a brake torque of 2.0 Nm. During sustained operation, the rotor can reach a rated speed of 6000 rpm, which suits high-throughput positioning tasks and short cycle times. Heat produced by copper losses is removed by natural convection, and two NTC thermistors monitor internal temperature to protect the winding. This arrangement allows the motor to run without a separate fan and gives the control system a direct indication of rising thermal load.

The motor has a locked-rotor torque of 2.3 Nm and a corresponding locked-rotor current of 3.3 A, values that describe startup loading when the shaft is not yet turning. Under rated excitation, the electromagnetic design yields a torque constant of 0.69 Nm/A, allowing the control loop to relate phase current directly to produced torque. Acoustic emissions stay at or below 58 dB(A), which helps limit machine noise in production areas where several axes may operate nearby. The assembly also tolerates mechanical shocks up to 6 g during transport or machine cycling, helping protect alignment and internal components.
