Product Description:
The SF-A4.0172.030-14.071 is a synchronous servo motor produced by Bosch Rexroth Indramat for the SF Servo Motors series. It serves as a rotary actuator that delivers commanded torque and speed to machine axes in automated equipment such as material-handling gantries, index tables, or packaging stations. A permanently mounted holding brake is integrated into the motor housing so that shafts remain fixed when system power is removed, preventing unintended motion on vertical or suspended loads. Its synchronous design supports accurate speed regulation and repeatable positioning when it is paired with a compatible servo drive. This makes the unit suitable for applications that require both controlled motion and secure holding at standstill.
The electromagnetic brake operates from a supply of 24 VDC and draws a rated current of 0.7 A during engagement. After power loss, the brake builds full clamping force in 25 ms; when voltage is restored, it releases again in 50 ms. Static locking capability is provided by a holding torque of 18 Nm, which supports load retention when the axis is at rest. Internally, the friction surfaces act on a rotor with a brake inertia of 3.1 × 10⁻⁴ kg·m², helping limit the effect of the brake on dynamic response. Acoustic emissions are limited to 58 dB(A), and a torque constant of 1.38 Nm/A gives the drive a predictable relationship between current and developed torque.
The mechanical section reaches a rated speed of 3000 rpm, while starting conditions may draw a locked-rotor current of 13 A until motion begins. Energy that must be dissipated during rapid deceleration is specified at 785 Ws, and the matching plug-in resistor value is 1.0 Ω. The assembly tolerates shocks up to 6 g, making it suitable for mobile or vibratory machinery. Construction follows the IM B5 flange-mount pattern for direct coupling to gearboxes or end plates, and this arrangement helps keep the motor centered on mounting faces. That mounting pattern also supports direct face installation where axial space is limited and shaft alignment must remain consistent. The brake can counter the motor's rated locked-rotor torque without slip.
