Product Description:

The SF-A4.0172.060-14.050 is a servo motor produced by Bosch Rexroth Indramat for the SF Servo Motors series. In automated machinery, this motor converts commanded drive current into mechanical rotation, allowing precise positioning or velocity control on packaging lines, pick-and-place axes, and similar motion tasks. Its integrated electromagnetic brake secures the load when power is removed, and a 142 mm square mounting flange aligns the housing to standard machine frames without extra adapter plates. This arrangement is useful on axes that must remain in place during power loss or controlled stops.

The drive can reach a rated speed of 6000 rpm, supporting fast cycle times for tasks that require high shaft velocity. A torque constant of 0.65 Nm/A links stator current to generated torque, helping the drive produce predictable output. When the rotor is locked, the shaft can deliver 17 Nm while drawing a peak current of 26 Arms. Dynamic performance is influenced by a rotor inertia of 40 × 10⁻⁴ kg·m², which supports moderate acceleration without demanding extreme drive current. A Ø24 × 50 mm keyed shaft transmits torque, and the mounting interface fits common machine connections. Power conductors are routed through a 4 × 6.0 mm² cable, while feedback and power share a size 1.25 circular connector that simplifies connection layout.

The axial bearing set tolerates an external load of 154 N, allowing moderate thrust forces from belt tensioners or vertical loads. During standstill, the holding brake supplies 18 Nm to secure the axis, and it is energized by a 24 VDC coil that draws 0.7 A through a 2 × 1.5 mm² brake cable. With the brake assembly installed, the motor weighs 20.7 kg and occupies 356 mm in overall length. That mass and length can affect mounting support, clearance around nearby components, and moving-axis payload limits.
