Product Description:

The SR.A4.0230.30-10.000 is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the SR Synchronous Servo Motors series. The unit is intended for industrial automation tasks that demand repeatable shaft positioning, such as indexing tables, pick-and-place arms, and gantry axes. When paired with a compatible drive, it translates current commands into controlled torque and speed, providing the mechanical power needed to keep processes synchronized and accurate across continuous or cyclic duty cycles.

A mounting flange of 142 mm follows IEC dimensions, simplifying direct installation on machine frames. The housing carries an IP67 rating, so internal components remain sealed against dust ingress and temporary water immersion during washdown cleaning. Under normal operation, the rotor can reach a rated speed of 3000 rpm, allowing quick indexing while staying below critical vibration zones. When the shaft is blocked, the motor can develop 22 Nm of stall torque while drawing up to 14 A from the drive. Those values indicate the load the motor can resist without motion and the current the drive must supply for sizing.

The integrated resolver supplies rotor position feedback with an accuracy of ±10 arcmin and a resolution of 8192 incr/rev, giving the controller enough granularity for smooth velocity loops. A mechanical inertia of 0.0054 kg·m² lets the axis accelerate without excessive drive effort, while the torque constant of 1.57 Nm/A links commanded current to produced torque for predictable motion tuning. The motor weighs 22 kg and measures 341 mm in overall length, so the installation must account for that mass and footprint. A 24 mm smooth shaft that extends 50 mm from the bearing journal transfers power to couplings without keyways.
