Product Description:

The SF-A3.0068.015-10.050 is a brushless servomotor from Bosch Rexroth Indramat in the SF Servo Motors series. It converts electrical power into regulated rotary motion for automated positioning tasks in packaging, assembly, and material-handling cells. By combining a permanent-magnet rotor with high-resolution feedback, the unit supports closed-loop speed and position control required for industrial robots, transfer systems, and CNC-controlled axes. Its compact flange-mounted format helps conserve installation space where several motion components must fit within a tight machine envelope.

The motor operates from a DC link voltage of 670 V, matching the power sections of Indramat drive controllers. Its rated speed is 1500 rpm, giving a continuous operating point before field weakening begins. A minimum bearing life of 20,000 h indicates expected service duration under normal loading conditions. The housing carries a protection rating of IP67, which keeps out dust and permits temporary immersion when the motor is mounted on machinery. Position data is supplied by an absolute encoder with 8 million incr./rev., and angular error remains within ±20 angular seconds to support fine contour tracking and small incremental moves. Sinusoidal E.M.F. commutation supports smooth torque production and helps reduce torque ripple across the usable speed range.

The motor body uses IM B5 construction, so the housing is intended for flange mounting without feet. The flange measures 116 mm across, and a 110 mm pilot diameter keeps the shaft centered against gearboxes or machine plates. Axial retention is aided by a center hole machined to DIN 332-DS M6 for drawbar fixtures. During transport or rapid indexing, the assembly tolerates shocks up to 6 g, which helps protect bearings and feedback components from sudden mechanical loads. A fully sealed structure permits washdown cleaning and supports use in machines exposed to moisture or airborne debris.
