Product Description:

The BL-ME200J-20SN servo motor is engineered by a leading producer Okuma. This unit represents BL Servo Motors series and delivers a rapid traverse on the X-axis at 40 m/min (1,574.80 ipm) which ensures swift linear movement during operations. It also achieves the same rapid traverse speed on the Y-axis at 40 m/min (1,574.80 ipm). On the Z-axis, the traverse speed is slightly lower at 32 m/min (1,259.84 ipm), balancing precision with speed.

This servo module further exhibits a spindle speed of 2000 min⁻¹ which supports rapid cutting and drilling processes. Its Z-axis ball screw lead is set at 16 mm (0.63 in.), while the X-axis ball screw lead is 20 mm (0.79 in.), optimizing the linear translation of rotary motion into precise movement. The design includes a Y-axis ball screw with a diameter of φ40 (1.57 in.) and a matching Z-axis ball screw diameter of φ40 (1.57 in.), maintaining consistent rigidity and accuracy. An acceleration rate of 4 m/s² enhances the system's ability to quickly reach operating speeds while a positional repeatability of ±0.01 mm guarantees high precision during repetitive tasks.

In addition, the BL-ME200J-20SN servo module supports a load capacity of 1200 kg to enable it to handle substantial mechanical forces. Its overall system weight of 18 kg makes it a compact yet sturdy unit suitable for various industrial setups. The controller interface is EtherCAT supported that facilitates high-speed digital communication for real-time monitoring and control. The operating temperature range is maintained between 10°C to 40°C, guaranteeing reliable performance under typical production conditions. This innovative unit is designed for a 100% continuous duty cycle so that it can operate non-stop during prolonged shifts.
