Product Description:

The SF-A2.0020.030-00.050 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and assigned to the SF Servo Motors series. Designed for closed-loop motion axes, the unit converts drive current into controlled mechanical rotation for positioning cylinders, pick-and-place heads, and other automated loads. Its built-in absolute encoder supplies feedback to compatible drives, allowing tight velocity tuning and repeatable moves across a 360-degree range. Compact length and a standardized flange simplify installation in machines where envelope dimensions are strictly limited. Integrated feedback also helps the drive maintain stable position control during repeated starts, stops, and reversals.

During continuous operation, the shaft reaches a rated speed of 3000 rpm. The motor has a torque constant of 1.5 Nm/A, so each ampere commanded by the drive produces 1.5 newton-meters and keeps current scaling straightforward. When the rotor is at a standstill, the windings draw 1.3 A, and the motor can hold 2.0 Nm of stall torque, which supports controlled setup checks at low speed. Position data are delivered at 8 million increments per revolution, allowing very fine command resolution on coordinated axes. This level of feedback supports smooth interpolation when several axes must move together.

Mechanical integration is aided by a square flange that measures 100 mm and matches a 95 mm pilot diameter for concentric centering on gearboxes or mounting plates. The rotor inertia of 3 × 10⁻⁴ kg·m² balances acceleration response with load smoothing, while the total mass of 5.5 kg keeps cantilever forces moderate. The motor uses IM B5 mounting, so the housing seats against a machine wall with the shaft extending forward. Two embedded NTC sensors support temperature monitoring during operation. A 4 × 1.5 mm² shielded cable entry provides the electrical connection and helps keep wiring organized at the motor housing.
