Product Description:
The SR-A3.0093.060-14.822 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the SR Synchronous Servo Motors series. Developed for precise positioning and speed control in automated assembly cells, pick-and-place heads, and packaging machinery, the unit converts three-phase drive output into controlled rotary motion. It uses an internal electromagnetic holding brake to retain loads during power-off events and resolver feedback so the associated drive controller can close the position loop with high angular accuracy.
During standstill, the brake exerts a holding torque of 10.0 Nm while drawing 0.66 A through its coil. When motion is commanded, the magnetic circuit develops torque in proportion to current at a constant of 0.67 Nm/A, so the drive can predict output by regulating phase current. If the shaft is prevented from turning, the winding can sustain a locked-rotor current of 13.5 A RMS, and the motor resists with a locked-rotor torque of 9.1 Nm. The brake is energized by 24 VDC and releases after 29 ms. Its friction assembly has an inertia of 1.06 × 10⁻⁴ kg·m² that must be overcome during startup. For emergency stops, a 3.3 Ω plug brake dissipates 785 Ws of kinetic energy, limiting mechanical stress and preventing excessive drive regeneration.
During rated operation, the rotor reaches 6000 rpm, and the drive must accommodate the associated back EMF and thermal rise. The rotating assembly has an inertia of 16 × 10⁻⁴ kg·m², providing moderate acceleration without overshoot on lightly loaded axes. The resolver feedback system provides a digital resolution of 8,192 increments per revolution with an accuracy of ±10 arcmin, allowing the controller to command fine incremental movements. The brake reengages in 20 ms, securing vertical loads almost immediately after power loss. Resolver feedback eliminates the need for an external encoder, reducing the number of additional components required around the motor. The internal holding brake also supports applications in which the shaft must remain stationary after drive power is removed.
