BL-ME200J-12TN-A

The Okuma BL-ME200J-12TN-A servo motor, part of the BL Servo Motors series by Okuma, delivers high-efficiency motion control with a Rated Output of 4.4 kW and a Rated Current of 25.9 Arms. Designed for integration with a Servo Drive Unit Type 75D, this model accepts an AC 141 V power source at an operating Frequency of 200 Hz, enabling rapid response in precision applications. The built-in Current Limit of 33 A provides surge protection and ensures safe operation under dynamic loads. With its compact footprint and optimized thermal management, the BL-ME200J-12TN-A supports high-power delivery while minimizing installation space. Early in the design cycle, emphasis on modularity and electrical compatibility simplifies both new machine builds and retrofit projects.

Performance characteristics of the BL-ME200J-12TN-A emphasize dynamic torque generation and precise speed regulation. An internal J-type control system coordinates commands with the integrated Okuma encoder, delivering feedback for closed-loop control. The motor features 8 pole pairs and a precision taper output shaft that enable a continuous operating speed of 3000 rpm and a continuous torque of 10 Nm. Continuous mechanical power of 2.9 kW is sustained through efficient copper windings and natural convection cooling. The absence of a holding brake reduces moving mass and simplifies coupling to downstream gearboxes or linear slides. This combination of electrical and mechanical attributes supports smooth acceleration, fine positioning, and repeatable cycle times.

Reliability and seamless integration are core to the BL-ME200J-12TN-A’s design. The motor housing meets IP65 protection standards, safeguarding internal components from dust and water ingress in shop-floor environments. Optimal performance is maintained within an ambient temperature range of 0 to +45 °C, with a maximum operating limit of +55 °C (with 20% efficiency reduction) and an altitude rating up to 1000 m MSL. Its compact, sealed enclosure and convection-cooled design eliminate the need for external fans, reducing maintenance requirements. Well-suited for machine tool spindles, printing presses, and automated assembly lines, this servo motor delivers dependable operation across a broad range of industrial applications.
