Product Description:

The Bosch Rexroth Indramat SF-A2.0020.030-10.000 servo motor belongs to the SF Servo Motors series. It is engineered for precise closed-loop rotation in packaging stations, pick-and-place modules, and other axes that need repeatable velocity and position control in industrial automation cells. The unit integrates an optical encoder and a smooth output shaft so it can be coupled directly to gear stages or belt drives without mechanical backlash.

With a nominal speed ceiling of 3000 rpm, the motor can deliver application-level motion profiles while staying within its thermal limits. The housing length is 198 mm, and the mounting flange measures 100 mm. The electromagnetic design provides a torque constant of 1.5 Nm/A, so drive current translates predictably into torque. At standstill, the motor reaches a stall torque of 2.0 Nm at a locked-rotor current of 1.3 A, helping the axis overcome static friction during indexing. Total rotor and encoder inertia is 3 × 10⁻⁴ kg·m², which helps keep acceleration times short when the motor is paired with lightweight loads. A Ø14 × 30 mm smooth shaft transfers power to the mechanical train, and the flange centering pilot helps simplify concentric alignment. No mating connector is supplied with the motor, so cable hardware must be selected separately.

Position feedback is handled by a single-turn STG encoder that generates 8 million incr./rev., and absolute angle accuracy is held within ±20 angular sec. Axial loading up to 70 N can be applied to the shaft without reducing bearing service life, which is useful when belt tensioners or helical gears impose thrust. The motor weighs 5.5 kg, which helps limit cantilever forces on compact gantries while still allowing stable installation through the 100 mm flange. A smooth shaft profile and the absence of a keyway reduce play in press-fit couplings and lower vibration at high speed.
