Product Description:

The SG-B3.220.017-14.010 is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the SG Synchronous Servo Motors series. It supplies controlled rotary motion for indexing tables, gantry axes, and other automation points that require accurate speed and torque regulation from a compact electromechanical package. Integrated feedback and a spring-applied holding brake allow the assembly to support motion control, position retention, and signaling within a single housing, simplifying machine layouts in demanding production environments.

The motor has a rated operating speed of 2200 rpm, enabling moderate-speed axes to operate without external gearing. At standstill, it develops 25 Nm of torque while drawing 20.9 A, establishing the continuous torque and current requirements when the load is stationary. Torque increases with current at 1.26 Nm/A, so each ampere produces a predictable rise in mechanical output. Its current rise time is 1.84 ms, giving the current loop a fast response to changing commands and disturbances. A 140 mm square mounting flange manufactured to accuracy class R aligns the shaft concentrically with connected gearheads. The bearing set tolerates axial forces up to 200 N, while the brushless design avoids the commutator wear associated with mechanically commutated motors.

Static holding is provided by a spring-applied brake that locks the rotor with 15 Nm of torque and releases when the control rail supplies 24 V DC ±10%. The brake mechanism weighs 1.3 kg and contributes 0.36 × 10⁻³ kg·m² of inertia, keeping its effect on acceleration limited during repeated motion cycles. The housing has an ingress protection rating of IP65, guarding the internal components against dust and water jets. The machined shaft measures Ø24 × 50 mm and supports direct coupling with compatible clamping or keyed hubs. A brushless resolver supplies continuous position feedback without contact wear, allowing the connected drive to monitor rotor position during packaging, material-handling, and general automation tasks.
