Product Description:
The SF-A4.0172.015-14.050 is a synchronous servo motor produced by Bosch Rexroth Indramat within the SF Servo Motors series. It operates with a matching digital drive to deliver controlled torque and speed for presses, pick-and-place gantries, and other CNC or material-handling axes. Its synchronous design allows the drive to regulate speed and torque precisely across programmed motion profiles. By combining closed-loop feedback with an integrated holding brake, the motor supports accurate positioning during motion and secure stopping when the axis is at rest.
At its rated operating point, the rotor turns at 1500 rpm, a speed suited to medium-torque machinery that uses steady velocity profiles. Position feedback is supplied by an absolute encoder with 8,000,000 increments per revolution, allowing very fine measurement of angular movement over a full turn. The permanent-magnet brake provides 18 Nm of holding torque and engages when the external control releases the 24 VDC supply, which draws 0.7 A during brake release. Its brake inertia of 3.1 × 10⁻⁴ kg·m² and brake mass of 1.04 kg add only a modest load to the shaft. A bearing set rated for 20,000 h supports continuous-duty operation over extended running periods. The brake uses a permanent-magnet design for fail-safe clamping when control voltage is removed.
Electrical integration with the drive controller is supported by a DC bus connection that tolerates a 670 V link, allowing the motor to share a common intermediate circuit with other axes in the system. The DC link capability also fits servo systems that distribute bus power across multiple connected axes. The rotor-stator assembly withstands shocks up to 6 g without demagnetization, and the front bearing can absorb an axial load of 154 N during rapid plunges, vertical mounting, or other thrust-producing motion. Acoustic emissions are limited to 58 dB(A), which helps keep operation quieter in enclosed machinery. Low acoustic output is useful in machine frames and production cells where several motion components operate nearby.
