BL-ME80J-40TN by Okuma

The Okuma BL-ME80J-40TN from the BL Servo Motors series by Okuma is a high-performance brushless servo motor engineered for precision motion control in industrial automation. Featuring a maximum motor speed of 4,000 rpm and a pneumatic clamp system delivering 1,500 Nm of clamp torque, this motor excels at securing and rotating heavy workpieces with exceptional stability. Its indexing accuracy of ±10 arc seconds ensures repeatable positioning for applications such as milling, grinding, and automated assembly lines. Designed to handle work weights up to 175 kg, the BL-ME80J-40TN provides a robust solution for tasks demanding both power and precision.

In detailed operation, the BL-ME80J-40TN supports an allowable load when table clamped of 24,800 N and an allowable work inertia of 4.48 kg·m^2, guaranteeing smooth acceleration under varying loads. The motor’s speed reduction ratio options of 1/90 or 1/45 adapt to diverse torque requirements, while the allowable wheel torque of 4,700 Nm offers substantial rotational force for heavy-duty machining. With an inertia converted into motor shaft value of 0.52×10^-3 kg·m^2, dynamic responses remain highly controllable. The precision clamp system and holding torque @72psi of 939 Nm contribute to the unit’s capacity to maintain firm workpiece positioning during high-torque operations.

Complementing its core specifications, the BL-ME80J-40TN meets IEC60034-1 standards, ensuring compliance with international safety and performance requirements. Its net weight of 145 kg enhances stability, reducing vibration and extending service life in continuous-duty environments. The motor is optimized for minimal maintenance, featuring durable components that withstand industrial conditions. With a proven track record in handling work weights up to 175 kg (or 375 lbs with tailstock), this servo motor delivers exceptional reliability, efficiency, and accuracy, making it an ideal choice for demanding production processes and high-precision machining operations.
