Product Description:
The SR-A4.0230.030-00.030 Servo Motor by Bosch Rexroth Indramat delivers high torque and efficient operation at a high rated speed. The motor comes with advanced thermal protection and precision bearings. It ensures long lasting performance in demanding industrial automation and motion control applications.
The SR-A4.0230.030-00.030 servo motor features a locked rotor torque of 22 Nm and operates at a rated speed of 3000 min⁻¹. The locked rotor current is 14 A and it delivers a torque constant of 1.57 Nm/A under conditions of 40 °C ambient temperature and a 100 K winding temperature rise. The servo motor includes a locating bearing positioned on the output side (flange side) that provides stability and alignment under load. The bearing guarantees a minimum service life of 20,000 hours. The flange size is 142 mm and the shaft measures 24 × 50 mm designed for reliable mechanical integration. The total motor length reaches up to 341 mm and it has a mass of 25 kg. The moment of inertia including the encoder is 54 × 10⁻⁴ kg·m². The SR series servo motor includes integrated thermistors in the windings for thermal motor protection which are evaluated through the connected servo module. The operating temperature range of the thermistor is from –5 °C up to + 155 °C.
Shock resistance of the SR-A4.0230.030-00.030 servo motor is rated at 6 g according to DIN IEC 68-2-27 with no impairment of function during mechanical impact. Noise emission is kept low not exceeding 58 dB (A) at a 1.0 meter distance as per EN 60034-T9. The insulation class of the servo motor is designated as Class F in compliance with VDE 0530 and DIN IEC 85 standards.
