Product Description:

The SF-A2.0020.030 servo motor is produced by Bosch Rexroth Indramat within the SF Servo Motors series. It is a rotary actuator intended to deliver precise position and velocity control for automated handling modules, packaging axes, and similar machinery. By converting electrical commands from a drive controller into controlled mechanical motion, the unit forms the primary moving element in closed-loop industrial automation. Its brushless construction minimizes maintenance and supports high duty cycles in continuous production.

These performance values describe how the motor works with the drive. The rated speed of 3000 rpm indicates the rotational velocity it can hold under continuous load without exceeding thermal limits. A torque constant of 1.5 Nm/A means that each ampere of phase current produces 1.5 newton-meters, which helps support current-based torque commands in the controller. For startup analysis, the locked-rotor torque reaches 2.0 Nm, while the locked-rotor current is 1.3 A at that condition. Dynamic response is aided by a rotor inertia of 3 × 10⁻⁴ kg·m², helping keep acceleration times short and supporting load-matching calculations.

The motor uses a square mounting interface with a flange diameter of 100 mm and IM B5 construction, which simplifies direct coupling to gearboxes or machine frames. Overall length without an integral brake is 198 mm, allowing compact installation inside linear slide nests. The housing has an IP67 protection rating, so dust ingress is prevented and temporary immersion will not impair operation. Despite the sealed design, the mass remains 5.5 kg, which helps limit reflected load on small gantry axes. Passive cooling by radiation and natural convection eliminates external blowers, and a shaft sized 14 mm by 30 mm transmits continuous torque quietly with a measured acoustic level of 58 dB(A). The assembly also tolerates shocks up to 6 g, supporting use on pick-and-place heads that are subject to rapid indexing.
