Product Description:

The SF-A3.0042.060-10.000 is an AC servo motor manufactured by Bosch Rexroth Indramat within the SF Servo Motors series. Designed for positioning and velocity loops in CNC axes, packaging machines, and material-handling gantries, the unit converts drive current into precise mechanical motion through a smooth 19 mm shaft. Integrated temperature sensing and encoder feedback allow the connected drive to monitor thermal load and rotor position, making the motor suitable for closed-loop automation tasks that require repeatable speed and torque. Its servo design also supports responsive starts, stops, and speed changes in high-duty motion systems.

At a rated speed of 6000 rpm, the rotor produces continuous velocity suited to high-cycle tooling. The electromagnetic design yields a torque constant of 0.70 Nm/A, so each ampere of phase current develops predictable drive torque. When the shaft is stalled, the motor can withstand a locked-rotor torque of 3.9 Nm while the winding draws up to 6.0 A. During plug braking events, the system can absorb 261 Ws of kinetic energy before an external resistor dissipates heat. Supporting data include a 223 mm overall length, a 5.6 Ω braking resistor value, and twin NTC sensors for thermal monitoring. These values help establish current demand, braking behavior, and operating limits for the connected drive system.

The low rotor inertia of 7 x 10^-4 kgm² supports fast acceleration without placing unnecessary load on the drive regulator. Position feedback is delivered by a single-turn absolute encoder with 8 million incr./rev., allowing the controller to issue very fine motion commands across the travel range. Installation uses the flange pattern classified as IM B5, so the housing aligns directly to gearboxes or machine frames without foot mounts. A total mass of 7.0 kg keeps handling forces moderate while still providing useful thermal capacity during continuous operation.
