Product Description:

The SF-A2.0026.030-10.050 is a permanent-magnet synchronous servo motor produced by Bosch Rexroth Indramat within the SF Servo Motors series. It serves closed-loop rotary axes in automated packaging, assembly, and material-handling stations where precise positioning and repeatable velocity profiles are critical. When paired with a compatible Indramat drive, the motor converts command current into controlled shaft motion for accurate speed and position control. Its compact format also helps it fit machine frames where available installation space is limited.

The motor operates from a DC link of 670 VDC, which supports strong electromagnetic excitation for responsive servo operation. A 100 mm square flange provides a common mounting pattern, and the IM B5 face-mount arrangement allows direct installation on machine plates or gear reducers. Continuous operation is rated at 3000 rpm, while a torque constant of 1.5 Nm/A gives a predictable relationship between current and developed torque. Heat is removed by natural convection, so the housing can dissipate losses without an auxiliary fan. An absolute value encoder supplies digital position data to the controller, and the smooth shaft supports precise coupling to clamping hubs with low runout.

At standstill, a locked-rotor current of 1.7 A produces a locked-rotor torque of 2.6 Nm, which supports reliable breakaway from static friction during startup. The motor also has a shock resistance of 6 g, helping it tolerate impact loads that can occur in dynamic machinery. All stated operating values apply up to an ambient temperature of 40 °C, provided airflow around the housing remains unobstructed. This operating limit is important for preserving thermal stability during continuous duty and repeated positioning cycles.
