Product Description:

The SF-A2.0041.030-14.050 belongs to the SF Servo Motors series produced by Bosch Rexroth Indramat. As a permanent-magnet servo motor, it supplies closed-loop rotary motion for positioning tables, pick-and-place arms, and similar automation axes that need repeatable accuracy within a compact 100 mm flange size. It is a frame-mounted unit for IM B5 face mounting and uses a 24 VDC brake supply so the machine can hold a load when the drive is disabled. This arrangement supports installations where the motor is bolted directly to a machine face and must maintain position after commanded motion stops.

The motor is designed for use with a DC link that can reach 670 V, allowing it to pair with high-voltage inverters without excessive current draw. A flange diameter of 100 mm sets the face-mount pattern and shaft height for this mechanical class, which helps the motor fit standard servo mounting locations. The electromagnetic system has a torque constant of 1.43 Nm/A, and the rated speed is 3000 rpm for continuous duty. During startup, the stator can draw 2.8 A to overcome static friction and produce 4.0 Nm of locked-rotor torque. Two NTC sensors in the windings report temperature to the controller, and the motor has a shock resistance of 6 g for axes that see rapid deceleration.

A holding brake delivers 3.2 Nm of static torque at the rated 24 VDC supply, which helps secure vertical axes when power is removed. The housing has an IP67 (except output side) seal that blocks dust ingress and withstands temporary submersion, although the shaft end should remain outside washdown zones. Dynamic response is supported by a rotor inertia of 6 x 10^-4 kgm², and airborne noise is limited to 58 dB(A). The motor also has a minimum service life of 20,000 h and uses IM B5 mounting for long-running automated cells.
