Product Description:

The SF-A2.0041.030-14.000 servo motor is produced by Bosch Rexroth Indramat within the SF Servo Motors series. It is a rotary actuator intended for positioning and velocity control in industrial automation cells, conveyors, and packaging lines. Integrating a single-turn absolute encoder, it reports shaft position directly to the drive for closed-loop operation, while the integrated holding brake keeps loads stable when power is removed. This combination supports controlled starts, accurate stopping, and repeatable motion in automated equipment.

During continuous motion the motor reaches a rated speed of 3000 rpm, meaning the shaft can complete 3000 revolutions per minute under nominal electrical and thermal limits. Each ampere applied to the windings produces approximately 1.43 Nm/A of torque, a constant that helps the drive respond predictably to current commands. At standstill the phase conductors draw 2.8 A(rms), so the inverter must supply this current whenever the axis is commanded to hold position without movement. Dynamic response is aided by the rotor inertia of 0.0006 kg·m², a comparatively low value that supports rapid acceleration and deceleration on light to moderate loads. The housing is rated IP67 except at the output flange, helping protect internal components from dust and water ingress when the shaft interface is properly sealed.

The holding brake can resist a static load of 3.2 Nm, so the axis remains fixed after the motor is de-energized until the brake is released. If the shaft is prevented from turning by a jam or other stalled condition, the windings can deliver up to 4.0 Nm of locked-rotor torque before protection intervenes. Total mass is 7.4 kg, which helps keep the assembly manageable in compact machine layouts. The motor uses a 100 mm square flange with a 253 mm housing length, allowing compact integration beside gearheads, pulleys, or direct-coupled drive elements.
