Product Description:
The VAC-MML11/7.5R-156C-R2 is a servo motor engineered by Okuma which is a global leader in industrial automation. It guarantees efficiency, reliability, and seamless integration with Okuma machines. It is part of the VAC Servo Motors series and ensures compatibility with the control systems.
The VAC-MML11/7.5R-156C-R2 servo motor is meant to be directly mounted on a machine spindle that makes it ideal for CNC applications where high-precision rotational motion is required. It can provide 7.5 kW of power continuously, effectively for operations that require long times under steady load conditions. Its windings have class F insulation that makes it to withstand temperatures up to 155°C which ensures durability. It is actively cooled using a fan that prevents overheating during continuous operation. This module supports a variable speed range from 1500 to 6000 RPM, which is crucial for applications requiring different speeds for different machining tasks. It can temporarily operate at 1.1 kW for short bursts (30 minutes) that indicates a high torque reserve for momentary load increases. This model consumes 46A current under normal continuous operation which ensures stable performance over long periods. It is included with high-quality bearings on both ends which supports smooth rotation and reduces friction and extends motor lifespan.
The VAC-MML11/7.5R-156C-R2 servo motor operates on 150 V which is a common voltage level for high-torque, high-performance servo motors. It is able to handle up to 59A temporarily for short bursts that allows it to deliver extra torque when needed. It operates with high efficiency and reduces energy consumption and heat generation. This module is compatible with both 50 Hz and 60 Hz power supplies that allows global usability in different electrical grids.
