Product Description:

The SF-A2.0041.030-10.000 is a brushless servo motor manufactured by Bosch Rexroth Indramat as part of the SF Servo Motors series. It is used in industrial automation where precise closed-loop motion is required, delivering rotational power to linear stages, indexing tables, and compact tooling axes. Its brushless design supports accurate speed and position control in systems that require repeatable motion.

This model is energized from a DC bus of 670 V, allowing it to pair directly with high-voltage IndraDrive inverters. Position feedback comes from a single-turn absolute STG encoder with 8 million incr./rev., and the torque constant is 1.43 Nm/A, which indicates the amount of shaft torque produced per ampere of current. Dynamic response is supported by a rotor inertia of 6 × 10^-4 kg·m², helping the motor accelerate quickly without excessive overshoot. The housing is sealed to IP67 except at the output flange, so dust and washdown splashes do not penetrate the main enclosure. The rated speed is 3000 rpm, the mounting arrangement is IM B5, the shaft measures 14 mm by 30 mm, and the overall length without a brake is 233 mm. Two integrated NTC sensors send temperature data to the controller during operation.

A square flange of 100 mm aligns the motor to gearboxes or frames with standard pilot diameters. During stall conditions, the motor provides a locked-rotor torque of 4.0 Nm while drawing a locked-rotor current of 2.8 A, which is useful when checking thermal limits and load conditions at zero speed. With a mass of 7.1 kg, the unit remains suitable for compact machine assemblies. Because it is supplied without a holding brake, the axis must be secured by an external clamping device or another retention method after power is removed.
