8LSA46.R0030D200-0

The B & R Automation 8LSA46.R0030D200-0 is a high-performance AC servo motor in the 8LS Synchronous Motors series designed for demanding industrial automation tasks. This motor combines robust construction with precise motion control, delivering a Rated Power of 3 kW at a Rated Speed of 3000 rpm. It features a flange mounting design and an integrated holding brake to ensure secure attachment and reliable stopping capability under dynamic loads. With IP65 protection, the 8LSA46.R0030D200-0 is sealed against dust ingress and low-pressure water jets, making it suitable for harsh manufacturing and processing environments. Resolver or encoder feedback options provide versatile integration into various control architectures for precision positioning.

In-depth technical specifications define the motor’s performance envelope: it operates on a Rated Voltage of 400 V three-phase supply and draws a Rated Current of 8.1 A at full load. The motor delivers a Rated Torque of 9.6 Nm and can produce a Maximum Torque of 28.5 Nm for transient acceleration phases. A Rotor Inertia of 7.7 kg·cm² minimizes control lag and supports rapid response in high-precision tasks. Its smooth shaft end and flange dimension of 100 mm enable straightforward mechanical integration. The self-cooling, free circulation cooling principle ensures continuous operation without external fans or coolant circuits, while the standard holding brake secures the shaft when de-energized.

Operational features emphasize reliability and dynamic response: the three-phase synchronous motor configuration summary indicates a standard bearing arrangement optimized for general-purpose automation. Protection class IP65 maintains uninterrupted performance in washdown or dusty conditions. Encoder technology via resolver feedback provides 10 arcmin precision for closed-loop control, enhancing accuracy in positioning and speed regulation. Weighing approximately 14.1 kg (without brake), the motor balances power density with manageable installation handling. The combination of high torque density and efficient cooling supports sustained operation at rated conditions, reducing maintenance intervals and downtime.

System integration is simplified by compatibility with common industrial servo drives and PLC-based motion controllers, using either resolver or encoder interfaces for real-time data exchange. The standard 400 V supply and moderate current draw lower installation complexity and wiring costs in three-phase systems. Typical applications include rotary labeling machines, valve actuation in process control, and direct-drive turntables for display platforms, where precise speed and position control are essential. The 8LSA46.R0030D200-0 excels in environments that demand robust ingress protection, high torque output, and seamless feedback integration.
