BL-ME80J-40TN
by Okuma
The Okuma BL-ME80J-40TN is a high-performance member of the BL Servo Motors series by Okuma, engineered for precision industrial automation. Featuring a maximum motor speed of 4,000 rpm and a robust clamp torque of 1,500 Nm via its pneumatic clamp system, this brushless servo motor ensures rapid indexing and secure workpiece holding. Its outstanding indexing accuracy of ±10 arc seconds underpins ultra-precise positioning, making it ideal for demanding machining and assembly operations.
Delving into technical specifications, the BL-ME80J-40TN supports an allowable work weight of 175 kg (385 lbs) and withstands an allowable load when table clamped of 24,800 N (5,555 lbf), alongside an allowable wheel torque of 4,700 Nm (3,464 ft lbs). The motor’s inertia converted into motor shaft is 0.52 × 10⁻³ kg·m² (alternative 1.66 × 10⁻³ kg·m²), delivering smooth acceleration and deceleration characteristics. Further versatility is provided by a dual speed reduction ratio of 1/90 or 1/45, and selectable maximum table speeds of 44.4 rpm or 88.9 rpm, allowing fine-tuned speed control across diverse workloads.
Built for industrial resilience, the BL-ME80J-40TN features a pneumatic clamp system and a holding torque @72 psi of 939 Nm (692 ft lbs), ensuring reliable operation under continuous duty. With a substantial net weight of 145 kg (319 lbs), the motor assembly offers enhanced stability and vibration damping. The design accommodates standard or special table diameter variation adjustments for seamless integration into existing installations. By conforming to IEC60034-1 standards for safety and performance, this servo motor enhances machining throughput, reduces cycle times, and delivers exceptional longevity—benefits that translate into higher productivity and lower total cost of ownership in industrial applications.
