SR-A3.0042.030-14.000

Product Description

SR-A3.0042.030-14.000 is a SR series servo motor from Bosch Rexroth. SR motors are permanently excited motors. They support electronic commutation. These motors work in combination with Servodyn-D inverter systems. SR series motors are equipped with a resolver for speed and position control. They have a compact design and the DC link voltage is 670 Volts. Special features of SR motors include sinusoidal emf, smooth aluminum frame, electronic rating plate for inverter optimization, IP67 protection rating, and cooling by natural convection. IP67 means that no dust can enter the motor enclosure, ensuring full protection against solid particles, and the motor can withstand immersion in water up to 1 meter for up to 30 minutes. The motor has a smooth shaft and supports temperature control.

A rating plate attached to the motor housing allows easy equipment identification. The permitted ambient temperature and altitude for rated output are 0 to 40 degrees Celsius and 0 to 1000 meters respectively. The motor housing features a flange for secure mounting. Ball bearings used on the motor have a service life that exceeds 20,000 hours. Locked-rotor torque of the SR-A3.0042.030-14.000 motor is 3.7 Nm and its rated shaft speed is 3000 RPM. The locked-rotor current rating is 2.3 Amps and the motor torque constant is 1.6 Nm/A at 40 degrees Celsius. Size of the flange on the SR-A3.0042.030-14.000 motor is 116 millimeters. The main shaft has 19 millimeter diameter and its length is 40 millimeters. Mass of the SR-A3.0042.030-14.000 motor is 7 kilograms (excluding the brake) and its length is 223 millimeters. The optional holding brake is rated for 10 Nm holding torque. Voltage and current rating of the brake is 24 Volts DC and 0.66 Amps respectively.
