Product Description:

The SF-A5.0460.030-10.050 is a synchronous servo motor built by Bosch Rexroth Indramat and assigned to the SF Servo Motors series. The unit serves as a rotary actuator within industrial automation systems where closed-loop velocity and position control are required. Its electromagnetic design converts drive current into mechanical torque so that machine tools, packaging lines, or handling modules can obtain repeatable motion profiles. This operating role makes it suitable for axes that need steady response during acceleration, positioning, and continuous speed regulation.

Incoming power is stored in the intermediate circuit at 670 V, a level used as the drive’s DC link potential for rapid current changes during acceleration. When the rotor is blocked, the winding draws 29 A, and the resulting locked-rotor torque peaks at 46 Nm; these values indicate the highest thermal loading on the drive electronics during stall conditions. Under normal operation, the shaft reaches a rated speed of 3000 rpm, providing mechanical output suited to many servo-controlled axes. The motor has an IP67 rating, which keeps out dust and allows temporary immersion so it can be installed on exposed machine sections without an added enclosure. This combination supports reliable motion on equipment that must hold accuracy while operating in demanding production areas.

Mechanical layout follows the IM B5 construction code, so the flange carries the main reaction forces and the shaft is not supported by feet. This arrangement simplifies mounting to gearboxes or machine plates and helps keep the motor aligned with the driven load. Internal thermal monitoring is handled by 2 NTC sensors embedded in the stator, enabling the controller to reduce current before winding temperature rises too far. Electromagnetic conversion efficiency is characterized by a torque constant of 1.58 Nm/A, which allows continuous torque to be estimated from the available phase current and supports stable control behavior across the speed range.
