Drives and Motor Control for Packaging Machinery
Packaging lines demand precision. Carotron supplies drives and motor controls for packaging machinery that OEMs and plant engineers rely on for responsive and reliable equipment. With DC drives, AC drives and interface system components backed by in-house engineering expertise, Carotron focuses on prompt commissioning and consistency. Find solutions that are thoroughly tested before shipment.
Helping Reduce Waste and Downtime Across Your Line
When a winder malfunctions, film material is at risk of bunching or tearing. Additionally, when a dancer system lags behind speed changes, the seal placement often drifts, compromising your product. Most occurrences of misaligned labels, telescoped rolls or emergency stops create material waste and lost output for an organization. Reliable motor controls provide the foundation for proper tension and for synchronizing speed changes and positioning.
The Right Drive and Control for Diverse Applications
Carotron’s products cover a wide range of packaging machinery automation needs. Whether you’re specifying components for a new OEM build or upgrading an existing line, obtaining the correct drive makes all the difference.
- DC drives: These drives provide consistent torque control for tension management. Our available models range from fractional-horsepower solutions to regenerative systems handling 700 horsepower. You can find DC drives featuring armature, tachometer and encoder feedback options.
- AC drives: Carotron AC drives provide sensorless vector control for conveyors, positioning systems and variable-speed applications. Browse different options from Yaskawa, Teco and Lenze lines, providing up to 1,000 horsepower.
- Soft starters: Professionals can reduce mechanical stress during motor startups, extending belt and bearing life.
Master Tension Control Obstacles
Materials like plastic film have narrow operating windows. Too much tension can result in stretching or tearing, while a lack of tension can cause slipping. Maintaining optimal tension as line speed and roll diameter change requires more than basic motor control, which is where Carotron steps in with useful solutions for your facility.
Web and film tension systems use torque-mode drives coordinated with feedback from dancers, load cells or ultrasonic sensors. CORTEX® LT system controllers calculate correct motor torque in real time based on roll diameter, line speed and material characteristics.
Dancer control systems absorb tension variations through material loops that rise and fall between drive sections. The dancer position provides immediate feedback for torque adjustments, preventing tension spikes. Interface components integrate dancer sensors with drive torque references to maintain accurate web handling during speed changes and splices. These capabilities include retrofits.
Carotron designs control system upgrades for coating lines, inspection frames and winding systems for your peace of mind.
A True Engineering Partner
Catalog distributors stock parts, but Carotron solves problems. An OEM designing a new machine needs drives matched to motor characteristics and startup support. Similarly, a plant engineer upgrading equipment needs compatibility with existing motors and confidence that the controls will encourage performance rather than limit it.
Our engineering team provides applications assistance from specification through commissioning. Engineers who understand tension control, multidrive systems and installation constraints review your inquiry.
For OEMs, this combination of product breadth and technical depth streamlines machine development. For plant operations teams, our approach enables upgrades that can enhance line performance without the need for full equipment replacement.
