Product Description:

The SF-A5.0700.030-10.000 is a servo motor produced by Bosch Rexroth Indramat for the SF Servo Motors series. This rotary unit converts electrical drive power into controlled mechanical motion for positioning axes in automated machinery, packaging stations, and transfer lines. Its integrated single-turn STG encoder delivers a resolution of ±20 arc-seconds and eight million increments per revolution, allowing the controller to issue precise velocity and position commands while monitoring actual shaft feedback in real time.

The motor supports a rated speed of 3000 rpm, enabling high cycle rates when paired with compatible inverters. A locked-rotor torque of 69 Nm provides high torque at standstill for holding loads during setup or emergency stops. Continuous torque production comes from a torque constant of 1.53 Nm/A, so the drive develops more than one and a half newton-meters for every ampere delivered by the power stage. The continuous M0 current limit of 45 A sets the thermal boundary for steady operation without excessive winding temperature rise. Dynamic behavior is influenced by a reflected inertia of 257 × 10⁻⁴ kg·m², which balances fast acceleration with stable control during rapid reversals.

Mechanical integration is aided by a total mass of 50 kg, which helps damp vibration in rigid machine frames. The square mounting flange measures 190 mm, matching common gearbox and adapter plates, while a splined output shaft sized at Ø32 × 58 mm transmits torque to couplings with minimal backlash. The housing endures shocks up to 6 g, helping protect the encoder and windings during transport or abrupt stops. An overall length of 483 mm keeps the motor compact for multi-axis gantries, and the single-turn encoder maintains position information after power cycling, which can reduce homing time at startup.
