Product Description:

The SF-A2.0041.060-14.000 is a synchronous servo motor developed by Bosch Rexroth Indramat for the SF Servo Motors series. The unit converts drive current into precise mechanical rotation, providing closed-loop motion control in industrial automation. It employs digital servo feedback for position verification and uses a plain shaft to couple directly to gearboxes or load fixtures. A blocking brake is not fitted, so holding torque must be provided externally when power is removed. All electrical terminations are routed on Side B of the housing for straightforward cabinet wiring. This arrangement supports clean cable routing and dependable axis control during repeated motion cycles.

The motor reaches a nominal speed of 4000 rpm, allowing high throughput on rapid-cycle indexing axes. Its torque constant of 0.40 Nm/A indicates how much shaft torque is produced for every ampere commanded by the drive, which helps with current-based control. During acceleration or transient load events, the winding set can absorb up to 164.8 A of peak current, and copper losses are limited by a winding resistance of 0.20 Ω. An inductance of 1.9 mH shapes current rise time, while the IP65 enclosure blocks dust and water jets so the motor may be mounted directly on the machine frame.

Dynamic behavior is influenced by a rotor inertia of 29 × 10⁻⁴ kg·m², and this relatively low value supports fast speed changes without excessive drive gains. The motor body weighs 16.5 kg, which provides stable mounting while keeping load on supporting structures moderate. Heat is shed through natural convection surface cooling, so forced air or liquid circuits are not required for continuous operation. A centering diameter of 110 mm aligns the flange to precision gear stages, and the motor can reach a maximum torque of 45.1 Nm for brief overload periods. The Side B shaft end is closed, which helps reduce contamination ingress at the unused end of the housing.
