Product Description:

The SF-A1.0023.060-14.050 is a rotary servo motor manufactured by Bosch Rexroth Indramat for the SF Servo Motors series. It converts electrical energy into controlled rotation for positioning axes, feed drives, and other closed-loop tasks in industrial automation environments. An integrated encoder supplies real-time velocity and position feedback so motion controllers can maintain tight tolerances during acceleration, constant speed, and deceleration phases. This arrangement supports repeatable motion in automated equipment where stable speed regulation and accurate positioning are required.

The motor reaches a rated speed of 6000 rpm, meaning the shaft can turn six thousand revolutions per minute without exceeding thermal limits. A torque constant of 0.69 Nm/A links phase current to produced torque, allowing the drive to predict load response accurately. Start-up requires a locked-rotor current of 3.3 A to overcome static friction. The housing mounts on a square flange that is 70 mm wide and uses a 60 j5 pilot for precise registration. Torque is transmitted through a ground steel shaft with a diameter of 11 k5 and an extension length of 23 mm. Including the encoder, the reflected rotor inertia is 1.20 × 10⁻⁴ kg·m², while the integral brake adds 0.12 × 10⁻⁴ kg·m² of inertia and 0.21 kg of mass.

With an overall length of 311.5 mm, the unit fits compact machinery while still providing a spring-applied holding torque of 2.0 Nm to secure vertical or suspended loads when power is removed. For emergency stops, the brake can sustain a locked-rotor torque of 2.3 Nm, helping prevent unintended motion. It releases at 24 VDC and draws 0.4 A, so standard PLC outputs can manage the coil without auxiliary relays. The brake is integrated into the motor assembly, which helps reduce the space needed for separate load-holding components on the machine.
