Product Description:
The SF-A4.0172.030-14.000 is a servo motor produced by Bosch Rexroth Indramat within the SF Servo Motors series. It converts drive-controller output into controlled mechanical rotation for conveying lines, pick-and-place modules, and other positioning tasks in automated assembly cells. The motor is intended for applications that need repeatable speed and position control rather than simple constant-speed operation. It is used where a servo amplifier must regulate acceleration, deceleration, and stopping behavior on a single axis. Integrated feedback and a holding brake place motion and retention functions in one housing.
The motor uses a 142 mm square flange and a 24 × 50 mm shaft, allowing direct coupling to moderate-duty gearheads. This layout also supports compact axis arrangements where mounting space is limited. Its DC link rating is 670 VDC, matching the output stage of Indramat HCS converters. At a rated speed of 3000 rpm, the magnetic design produces a torque constant of 1.38 Nm/A for fine current control. Total reflected inertia, including the feedback unit, is 40 × 10⁻⁴ kg·m², which supports quick acceleration without excessive drive current. The single-turn absolute STG encoder has an accuracy of ±20 arcsec and a resolution of 8 million increments per revolution. This feedback allows the controller to maintain precise position information throughout the servo loop. With the shaft locked, the startup condition can reach 13 Arms without exceeding the stated locked-rotor load.
The spring-applied holding brake provides 18 Nm of static torque to secure vertical or suspended axes during power-off. Brake power is 24 VDC with a ±10% tolerance and 5% ripple allowance. Coil excitation draws 0.7 A, which helps limit internal dissipation inside the motor enclosure. The housing reaches IP67 when the mating connectors are installed, so the motor can tolerate coolant splash and temporary immersion without additional covers. This sealing arrangement helps protect internal components in wet or washdown-prone machine areas.
