Product Description:

The BL-ME120J-40TN s\Servo motor is ideal for high-precision applications. Okuma created it for high demanded motion control systems, which require dependability, efficiency, and consistent output. Adherence to worldwide electrical and mechanical safety criteria is ensured by the motor's compliance with IEC34-1 standards.

The BL-ME120J-40TN servo motor's three-phase permanent magnet synchronous design allows for exact control of torque and great efficiency. With a stall torque of 12 Nm, it offers excellent holding capacity when subjected to load. The motor runs steadily with no heat stress, thanks to its 14.6A current rating. Its 267 Hz operating frequency guarantees quick reaction and fluid motion. In applications where continuous and dynamic torque delivery is required, the 8-pole arrangement optimizes performance by increasing torque production. To improve system efficiency and voltage balancing, the motor uses a Y (Star) winding connection. Class F insulation ensures it will remain durable even when subjected to high working temperatures. The use of high-tech materials and meticulous engineering results in a product with a long lifespan and low maintenance requirements.

|The strong interior of the <. improves mechanical stability. Improved thermal dissipation from its redesigned winding structure reduces energy loss and maintains efficiency. The motor's constant power rating of 3.0 kW ensures consistent performance in dynamic industrial automation activities. The motor is ideal for controlling fast-moving objects because it runs at 159V nominally and can reach 3000 RPM at its peak. The motor performs continuous duty cycles with precise motion. The servo motor ensures the smooth integration of complex automation systems. High speed and torque stability make motion control reliable in difficult situations. Due to its longevity, efficiency, and performance, the servo motor is essential to high-tech motion control systems.
