Product Description:

The SF-A1.0008.060-14.000 servo motor is supplied by Bosch Rexroth Indramat as a member of the SF Servo Motors series. It is a permanent-magnet synchronous unit intended to deliver precise rotational motion for positioning axes, packaging stations, and other closed-loop automation modules that need rapid speed changes and repeatable accuracy. Its closed-loop response supports accurate starting, stopping, and repeatable position control in compact automation equipment.

A square mounting interface with a 70 mm flange allows direct coupling to gearboxes or machine plates, and the shaft is cut to Ø11 × 23 mm for load transfer without adapters. Continuous operation is possible up to 6000 rpm; this speed ceiling marks the mechanical limit for couplings and bearings in high-cycle tooling. The torque constant of 0.6 Nm/A links drive current to produced torque, allowing straightforward sizing of the power stage. Dynamic behavior is aided by a rotor inertia of 0.43 ×10⁻⁴ kg·m², which helps keep acceleration times low with minimal overshoot. The motor can accept an axial thrust of 33 N along the shaft without degrading bearing life, and it withstands a locked-rotor current of 1.35 A that yields 0.8 Nm of stall torque. Total length, including the integrated brake, is 231.5 mm, which helps verify cabinet depth and slide clearance.

The holding brake supplies 2.0 Nm of static torque when energized at 24 V DC and draws 0.4 A, letting vertical axes remain fixed after power removal. A sealed housing rated at IP67 blocks dust ingress and water jets, so the motor can be washed down or mounted on open frames. Feedback is provided by a high-density incremental encoder that returns 8 million incr./rev. with a stated precision of ±20 arc-seconds, supporting very fine positioning. The windings are designed for a 670 V DC link, matching common multi-axis inverters, and the brake circuit is isolated from the power electronics to simplify wiring.
