Product Description:
Weighing 7 kg, the 8LSA46.DB045D300-3 minimizes support structure requirements which eases integration into compact machinery. The leading producer B & R Automation designed this module and uses a rated power of 1.41 kW that supplies sufficient torque for light‑duty motion tasks which maintains process consistency. Representing 8LS Synchronous Motors series, the variant includes an absolute EnDat as encoder type and also provides multi‑turn position feedback method for a refined closed‑loop accuracy.
International protection class of IP65 protects it against any harm from dust or water, simply support in providing long service life in any type of environment. “46” denotes a frame size that balances torque density and size constraints which optimizes machine footprint. A rated speed of 3000 RPM aligns with standard three‑phase grid frequencies to simplify drive tuning. The servo motor of type classification supports precise motion profiles which enhances servo loop performance. The wide power supply range of 200‑480 V AC integrates with varied industrial mains which avoids extra voltage conversion. Its self-cooled design dissipates heat independently, minimizing reliance on additional cooling systems and lowering maintenance requirements.
The device’s torque is rated as 4.5 Nm, therefore, it delivers constant force during continuous cycles, maintaining consistent output in repetitive operations. This B&R’s 8LSA46.DB045D300-3 component has a rotor inertia value of 0.41 kg·cm² which reduces control lag in rapid directional changes with an ambient temperature range of -15°C to +40°C which suits diverse industrial settings. This also features 5 pole pairs which ensure smoother torque delivery and enhanced electromagnetic efficiency during synchronized operation.
Frequently Asked Questions about 8LSA46.DB045D300-3:
