Product Description:

The SF-A4.0230.030-00.050 is a three-phase servo motor produced by Bosch Rexroth Indramat within the SF Servo Motors series. Designed for positioning and speed control tasks, the unit converts drive output from the associated amplifier into mechanical rotation for gantries, packaging axes, and other general-purpose machinery used in industrial automation. Its three-phase configuration supports stable operation in servo systems that require accurate motion and repeatable response under changing load conditions.

Its rated operating range includes a maximum speed of 3000 rpm, allowing the drive controller to work within the motor's back EMF limits. During stall or jam conditions, the shaft can deliver 22 Nm while drawing up to 14 A, and these locked-rotor values help with protection-device selection. A torque constant of 1.57 Nm/A relates commanded phase current to produced torque for closed-loop control. For dynamic braking, the windings connect to an external resistor of 1.0 ohm that dissipates kinetic energy. The casing produces a sound pressure of 58 dB(A) at nominal load, which supports use in areas near operating personnel. Electrical terminations use connector size 1 on a 4 x 2.5 mm² cable, but the mating plug is not included. The flange follows the IM B5 construction code, so the motor mounts by its face rather than by feet.

Mechanical endurance includes a nominal bearing life of 20,000 h, calculated for the permitted radial and axial loads on the shaft. Within that limit, the shaft may sustain an axial thrust of up to 154 N without reducing service life. During transport or sudden production stops, the assembly can withstand shocks of 6 g for short durations. The motor can be installed in vertical or horizontal orientations when the face-mount arrangement and specified cabling are used.
