Product Description:
The SF-A4.0172.030-04.030 is a synchronous servo motor produced by Bosch Rexroth Indramat in the SF Servo Motors series. Intended for integration with IndraDrive and other digital drives, it delivers feedback-controlled rotary motion to indexing tables, pick-and-place axes, and automated assembly stations. By combining a permanent-magnet rotor, encoder feedback, and an electromechanical holding brake, the unit supports repeatable positioning and secures suspended loads whenever power is removed.
The shaft can sustain a mechanical end thrust of 154 N, which helps limit bearing stress in coupled applications. The holding brake engages within 25 ms and releases within 50 ms when energized, allowing predictable stop-and-go sequences on vertical slides. The motor is intended for use with a drive system whose DC bus may reach 670 V, so insulation class and drive selection must suit this level. The housing uses a square mounting interface with a face dimension of 142 mm, matching machines built for this frame size. Two NTC sensors embedded in the windings monitor temperature for thermal protection. The absolute encoder supplies multi-turn position data without homing, and the assembly withstands shocks up to 6 g during transport or installation.
The brake can hold a static load of 18 Nm at the specified 24 VDC supply, maintaining axis position during emergencies or shutdowns. If the rotor is stalled, the drive may deliver up to 13 A of locked-rotor current during overload events. Continuous operation is optimized for a rated speed of 3000 rpm, balancing output velocity and thermal rise in normal service. The torque constant is 1.38 Nm/A, which allows output torque to track phase current in a predictable way for mid-inertia servo applications.
