Product Description:

The SF-A4.0172.015-10.050 servo motor is manufactured by Bosch Rexroth Indramat within the SF Servo Motors series. It serves as a rotary actuator for closed-loop position and velocity control in packaging, material-handling, and general automation lines. A permanent-magnet rotor and an optimized stator design let the unit deliver commanded torque without external gear reduction. The motor is intended for dynamic axis applications where fast response, repeatable motion, and stable control behavior are required across changing load conditions.

Its power stage accepts 670 V on the DC link, enabling high power density while keeping phase currents moderate. Electronic commutation uses a Sinusoidal back-EMF profile, which helps smooth low-speed torque output and supports steady rotation. Shaft position is reported by Absolute Value encoder feedback, so the axis can begin controlled motion immediately after power-up. Under nominal load, the rotor maintains 1500 rpm, providing a stable operating speed for coordinated servo tasks. Output and feedback are routed through a single plug-in connection, which helps keep cabling compact in multi-axis cabinets and reduces the number of separate external interfaces.

An IP67 housing prevents dust ingress and resists short-term immersion, making the motor suitable for areas exposed to moisture, coolant spray, and airborne debris. A machined Aluminum frame dissipates heat efficiently while keeping the overall motor mass relatively low. The motor withstands shocks up to 6 g, which supports use on indexing axes and other equipment that may see abrupt motion changes or rapid stopping events. Sound pressure during continuous duty stays below 58 dB(A), which helps limit operating noise near the machine. Two embedded thermal probes, specified as 2 NTCs, relay winding temperature information to the drive so protective derating can occur before excessive heat affects internal insulation.
