8MSA3L.E0-31
The 8MSA3L.E0-31 is a high-performance synchronous motor from B & R Automation within the 8MS Three Phase Synchronous Motors series. This compact unit features a frame size 3 design with a robust flange mount configuration for secure installation. It delivers a maximum input speed of up to 6000 RPM and accommodates an operating temperature range of -10°C to +90°C to ensure stable performance across diverse environments. The motor carries an IP54 or higher enclosure protection rating, safeguarding internal components from dust ingress and splashing water for reliable operation. Compact yet powerful, it weighs 1.75 kg prior to optional brake additions, ensuring easy handling and integration.
With a precision-engineered 3-stage reduction gearbox providing a gear ratio of 31:1, the 8MSA3L.E0-31 achieves a peak output torque of 1.6 Nm for demanding motion control tasks. The input shaft size E0 aligns seamlessly with standard couplings, while its low backlash (typically < 8 arcmin) ensures minimal positional error in high-precision applications. The motor’s moment of inertia of 0.18 kg·cm² (without brake) delivers rapid acceleration and deceleration with controlled dynamic response. Capable of reaching maximum input speeds of 6000 RPM, the motor maintains responsiveness and torque consistency, even under transient load conditions.
Operational resilience is enhanced by a radial load capacity of ≤ 200 N at the shaft end and an axial load capacity of ≤ 200 N during installation, providing robust support without compromising gear integrity during setup. The flange mount arrangement simplifies mechanical coupling and alignment, reducing installation time. A one-year warranty reflects the manufacturer’s confidence in component durability and quality control. At 1.75 kg, the lightweight assembly minimizes inertia on the system while enabling smooth, precise positioning with minimal overshoot.
Integration of the 8MSA3L.E0-31 into industrial automation systems is straightforward thanks to its standard flange interface and compatible mounting dimensions. This motor excels in robotics, pick-and-place machinery, and miniaturized automation equipment where compactness and precision are paramount. Its high torque density, low backlash characteristics, and wide operating temperature envelope make it ideally suited for both controlled lab settings and demanding factory floors. Engineers will appreciate the motor’s balance of power, precision, and reliability when optimizing motion control solutions in diverse industrial contexts.
