The Ultimate Servo Feeder
The Variax OPUS1 series is a high-performance servo feeder that is optimal for use in motor core production lines for hybrid, PHEV, and EV car motors.
By integrating a high capacity servo motor and roll into one body, it achieves world-class performance.
The driving servomotor is operated according to a unique cam curve.
Servomotor and cam curves are also used to control vertical roll motion and the release mechanism, allowing the OPUS series to feed thin and soft materials.
The OPUS series control system is also equipped with a monitor function, diagnostic function, anda large monitor. Its communication function makes it possible to check the operation from a remote location. This combination greatly improves its operability.

*1 Please check the separate feed capacity diagram.
*2 If the motor is water cooled, you will need to prepare your own cooling system (chiller) and hoses.
Use hoses with an inner diameter of φ9 mm.
When you are making or purchasing a chiller, select a chiller with the following specifications.
・ Cooling capacity: You need a chiller for a standard 1.5 kw or higher capacity motor, and for a 4.2 kW or higher capacity motor.
・ Minimum circulation rate: 7.0 L/min.
・ Preset operating temperature maximum: 35°C
・ Please choose a chiller and pipes that do not contain copper.
*3 This is the amount of air used for cooling an air-cooled motor air. (The motor capacity depends on the volume of cooling air supplied.)
