Product Description:

The SR-A4.0230.030-10.030 Servo Motor constitutes the manufacturing product of Bosch Rexroth Indramat. The synchronous motor exists for industrial automation tasks that require precise operations. The servomotor functions under continuous torque conditions which correspond to S1 characteristics. At 55 °C the unit operates within its defined specifications.

When not equipped with a holding brake the SR-A4.0230.030-10.030 servo motor has a 22-kilogram mass. Wrapping a holding brake around the system elevates its weight to 23.7 kg. The servomotor extends to 341 mm in its original form without a brake system installed. The installed brake extends the motor length to 388 mm. This servo motor produces force tolerance through the axial dimension up to 154 N. The designed load system maintains operational stability during all motions. The specified minimum operating energy for brief periods is 785 Ws. The installation of the brake function enhances the motor's operational capacity under cycle pressure demands. Technically the measured winding resistance of this unit amounts to 1 Ohm. The SR-A4.0230.030-10.030 Servo motor maintains compatibility with electromagnetic cables that have 4 × 2.5 mm² dimensions. To enable braking operation the necessary cable size should be two pieces of 1.5 mm². The available maximal conductor diameter for this specification is 4 millimeters squared.

The SR-A4.0230.030-10.030 Servo motor receives testing at an electrical voltage of 2500 V AC. Operation reliability together with insulation strength is ensured. The device uses a 35 mm top hat rail for its installation. The installation uses a DIN standard basis to enable simple integration steps. The motor operates under the protection category IP20. The protective feature of the motor safeguards it against solid materials exceeding 12 mm in size. The design parameters of this motor match well with minimal enclosure dimensions as well as protection needs.
