Product Description:

The SF-A3.0093.030-00.210 is a servo motor produced by Bosch Rexroth Indramat within the SF Servo Motors series. It converts drive current into controlled torque for numerically controlled tooling, packaging lines, and other motion-focused installations where precise rotary motion is required. The motor integrates into digital drive systems that require high repeatability, stable speed control, and short response times during frequent start-stop cycles. This makes it suitable for axes that must track command changes closely without sacrificing smooth rotation.

As a Brushless Servomotor, it uses Sinusoidal E.M.F. commutation to help minimize torque ripple across the rotation range. The permanent-magnet design provides a 1.35 Nm/A torque constant, so each ampere delivered by the drive contributes that level of steady torque. Under locked-rotor test conditions, the shaft can develop 8.1 Nm while drawing 6.0 A. During continuous operation, it reaches a rated mechanical speed of 3000 rpm, allowing direct coupling to gearless loads in applications that need consistent high-speed motion. Acoustic emission remains at 58 dB(A) at nominal speed, which supports use in production areas where lower operating noise is preferred.

Precise rotor position is captured by an Absolute Value Encoder, enabling the controller to recover angular data immediately after power-up without a homing cycle. The mechanical interface complies with the IM B5 flange arrangement, which centers the bearing housing against the machine plate and helps simplify axial alignment of couplings. The aluminum body is tested for shocks up to 6 g, which helps protect the motor during transport and rapid machine movement. Two NTC thermal sensors embedded in the stator windings send temperature data to the drive so current can be reduced before insulation limits are reached. This thermal monitoring supports stable operation when the motor is exposed to changing loads over repeated cycles.
