Product Description:
The Bosch Rexroth Indramat's SR-A4.0125.030-04.000 synchronous servo motor is very accurate and reliable for use in industrial automation. The servo motor was designed with strong performance specifications to fulfill demanding operating requirements, that allow it to be used for tasks that require high accuracy and speed.
The SR-A4.0125.030-04.000 synchronous servo motor can reach a maximum speed of 3000 rpm and has a locked-rotor torque of 14.5 Nm. The servo motor works accurately at a locked-rotor current of 10.6 A and has a torque constant of 1.37 Nm/A. With the encoder included, the servo motor has a moment of inertia of 30 × 10⁻ kgm², which makes sure that it rotates smoothly. According to EN60034-T9, the loudest noise that can be heard from 1 meter away is 58 dB(A). VDE 0530 and DIN IEC 85 both put thermal shielding in the class F group. The motor's surface can get as hot as 100°C, so a touch guard is needed to keep people safe in some situations. A strong design meets the shock resistance standard of 6g set by DIN IEC 68-2-27, that makes sure it works even in changing operating conditions.
Without the retaining brake, the SR-A4.0125.030-04.000 synchronous servo motor may reach a length of 277 mm. The servo motor has a shaft with a keyway and a feather key to ensure secure mounting. An extra surface ventilation system can be added to the motor to improve its efficiency. The flange is 142 mm wide, the shaft is Ø24 ×50 mm long and the servomotor weighs 16 kg without the holding stop. The motor's noise level is also in line with industry standards so it can meet strict operating needs. The motor’s cooling system uses natural convection and radiation to maintain continuous performance while also protecting the structure and keeping operations stable.
