The Ultimate Servo Feeder for Motor Core Lines: Introducing the Variax OPUS1 Series

As electric vehicle technology accelerates, so does the demand for smarter, faster, and more precise manufacturing solutions. At Sankyo Automation, we’re proud to introduce the Variax OPUS1 Series — the most advanced servo feeder system for motor core production lines used in hybrid, PHEV, and EV vehicle motors.

Built for High-Performance, Designed for the Future

The OPUS1 Series combines high speed, high precision, and exceptional reliability in one streamlined unit. By integrating a high-capacity servo motor and roll mechanism into a single body, this servo feeder achieves industry-leading performance, particularly in applications where feeding thin, wide, or soft materials is critical.

Whether you’re working with the latest EV motor core designs or scaling production to meet growing demand, OPUS1 delivers the speed and repeatability your line requires — with feed speeds exceeding 120 m/min and repeat accuracy of ±0.03 mm.

Smart Motion, Smarter Operation

What sets the OPUS1 apart is its use of a unique cam curve to control both the driving servomotor and the vertical roll motion — including the release mechanism. This approach enables ultra-smooth, stable feeding of even the most delicate materials, while maximizing throughput and minimizing material distortion.

The control system includes:

• A large, intuitive monitor

• Advanced diagnostic and monitoring functions

• Remote communication capabilities for real-time system checks and data access

• Multilingual interface and global compatibility for easy integration across regions

Versatile Models for Every Application

With four models available — OPUS1-200, OPUS1-300, OPUS1-450, and OPUS1-650 — the series offers flexibility to match your specific material width and feed length requirements. Each model supports material thicknesses up to 2 mm and stroke rates up to 1,000 strokes per minute, depending on configuration.

OPUS1 Model Range Highlights:

Model	Max Material Width	Max Feed Length	Max Feed Speed	Product Weight
OPUS1-200	200 mm	200 mm	80+ m/min	220 kg
OPUS1-300	300 mm	300 mm	120+ m/min	240 kg
OPUS1-450	450 mm	450 mm	120+ m/min	415 kg
OPUS1-650	650 mm	650 mm	120+ m/min	480 kg

Note: Water-cooled motor options are available for higher throughput and temperature control.

Engineered for Easy Integration

Installing the OPUS1 is simple — it’s designed to fit easily into existing press lines and integrate seamlessly with EVR1 configurations. The unit also includes features like:

• Improved roll cleaning accessibility

• Secure safety systems

• Built-in preventive maintenance alerts

• IoT compatibility for Industry 4.0 readiness

Supporting the Future of EV Manufacturing

From material handling to quality assurance, the Variax OPUS1 Series helps manufacturers meet the strict demands of modern electric motor production — without sacrificing reliability, speed, or control. Whether you're retrofitting a current line or launching a new one, OPUS1 is the smart investment in your EV future.
