Product Description:

The SF-A4.0172.015-04.000 is an AC servo motor built by Bosch Rexroth Indramat for the SF Servo Motors series. It converts commanded currents into precisely regulated torque and speed so rotary axes in packaging lines, pick-and-place gantries, or indexing tables reach and hold the requested position without mechanical overshoot. A permanently excited rotor, a flange-mounted frame, and a factory-mounted feedback unit let the motor report position directly to the drive controller and complete the closed loop required for industrial automation.

This model delivers a rated shaft speed of 1500 rpm, allowing moderate-speed motion profiles with consistent velocity tracking. A spring-applied holding brake supplies 18 Nm of static torque, and it is released by the drive over a control line carrying 24 VDC while drawing just 0.7 A. The integrated single-turn absolute encoder resolves position changes down to 8 million increments per revolution, so the controller can issue fine motion commands without relying on external scales. The brake supports load holding at standstill, while the encoder allows precise motion control during travel.

The housing carries an IP67 protection rating, meaning it is dust-tight and can withstand temporary immersion, while internal components tolerate shocks up to 6 g that may occur during rapid machine indexing. Axial thrust on the output shaft can reach 154 N without degrading bearing life, and the face-mount configuration follows IM B5 so the motor aligns easily to gearboxes or belt pulleys. Encoder accuracy of ±20 arcsec keeps angular deviation low over a full rotation, and the 58 dB(A) maximum acoustic noise level helps limit sound output in the surrounding machine area. Its sealing and construction make it suitable for washdown or outdoor conveyor stations.
