Product Description:
The 8MSA3L.R0-W0 is a three-phase synchronous motor manufactured by B & R Automation within the 8MS Three Phase Synchronous Motors series. The unit serves as a compact drive element for positioning and continuous-duty axes in industrial automation lines, translating inverter current into controlled rotary motion for belts, pumps, or indexing tables.
Under nominal load the motor delivers 0.99 kW of mechanical power at a shaft speed of 4500 min-1, drawing only 2.1 A to generate a continuous torque of 2.1 Nm. These rated figures define the steady-state design point that drive engineers use to size inverters and select gear ratios. A resolver mounted on the B-side provides absolute rotor position feedback while keeping the encoder insensitive to electrical noise. The power and feedback connectors also exit on the B side, streamlining cable routing in tight cabinets. With an inertia of 1.5 kg cm² and a mass of 3.65 kg, the rotor responds quickly to speed commands without overloading lightweight mechanics. An integrated oil seal prevents lubricant migration along the shaft, extending service life in wash-down or lubricated environments.
For short accelerations the motor can reach a shaft output of 10 Nm while the drive supplies up to 12.4 A; this overload margin covers rapid indexing or sudden load changes. If motion stops abruptly, a stall torque of 2.5 Nm remains available to hold position using drive current alone. Environmental protection is ensured by the IP65 enclosure and by the dedicated shaft seal mentioned earlier, allowing installation in dusty or splash-prone zones. The magnetic design yields a torque constant of 1.04 Nm/A, giving predictable current-to-torque linearity across the servo loop.
