8LSA55.R2030D000-3

Product Description:

B&R Automation’s 8LSA55.R2030D000-3 is a magnificent AC servo motor that requires a mains input voltage of 400 to 480 V. At rated operating conditions, this servo motor achieves a shaft velocity of 3000 rpm. Unlike other synchronous three-phase motors manufactured by B&R, this unit has four pole pairs or eight poles. Each pole in the machine’s stator has a mechanical separation of 45 degrees. With this type of pole construction, the machine achieves a maximum speed of 9000 rpm. Depending on the operating conditions, the servo motor’s output torque may vary from 11.6 Nm to 12.5 Nm. Between the two values, the higher one represents stall conditions.

At standstill operation, the 8LSA55.R2030D000-3 also draws a slightly higher current. Compared to the nominal current value of 7.1 A, the machine can draw up to 7.7 A at standstill operating conditions. Assuming base speed and nameplate values, however, this servo motor delivers a typical power of 3.64 kW. Since the 8LSA55.R2030D000-3 employs no holding brake, it has a total mass of 10.4 kilograms. Furthermore, it also features a very low rotor moment of inertia of 8.19 kg(cm^2). Similar to other servo motors manufactured under the 8LSA product umbrella, this servo motor does not employ a surface or liquid cooling system.

Due to its compact design and wide output characteristics, the 8LSA55.R2030D000-3 can accommodate small to medium mechanical loads during operation. Depending on the type of system, this servo motor can be operated at lower driving speeds to achieve a maximum torque of 41.4 Nm. For most AC machines and motors, the torque typically decreases for higher driving speeds. With its water-based coating, this servo motor has high corrosion resistance and a protection rating of IP 65.
