Eliminate Unsightly “Bars” Across your Substrate with Direct Drive Technology

Reprint of Kollmorgen Technical Article posted January 08, 2014, by Tom England

Coating and lamination applications demand precise speed regulation in order to avoid velocity ripple that causes uneven coating and undesirable horizontal bars across the substrate.  The key to achieving the most uniform coating is minimizing the variations in velocity as well as in metering of the coating material.  
Coating and laminating applications are characterized by compliance caused by the elasticity of the web, which in turn produces variations in torque requirements.  Web handling machines face the challenge of handling these loads while avoiding velocity ripple that can cause uneven coating and unsightly horizontal bars across the substrate.  As an example, consider film coating, where depositing a dark film onto the substrate material at varying velocity would result in a series of dark and light “bars” across the material.  As web speed and quality requirements have increased, the inevitable inaccuracies in the mechanical transmission and servo system have become a limiting factor on coating and laminating uniformity. 

Effect of Mechanical Transmissions 
Mechanical transmissions can have a negative impact on coating and laminating quality by causing tooth or belt chatter.  Backlash is inevitable in any mechanical transmission system.  Transmission components such as lead screws, gearboxes, and belts and pulleys all contribute error between the motor and the load.  Even when a geared system is tuned very tightly, within a short period of time the gears will wear and backlash will begin to occur.  Backlash causes the roller and cylinder to rapidly accelerate and decelerate as each gear teeth bounce back and forth against each other.  The result is uneven coating of the substrate manifested by the appearance of alternating light and dark horizontal lines on the product.

Traditional Mechanical Setup

Advent of Direct Drive Systems

In some cases these concerns can be adequately addressed by selecting high-quality mechanical transmission components with ultra-precision tolerances.  However, the added expense can become prohibitive and the components will still wear eventually.  The ultimate solution is a direct drive rotary system, which eliminates the transmission altogether.  In direct drive systems, the motor directly drives the load.  The accuracy of a direct drive solution can be up to 60 times better than that of traditional systems and audible noise can fall by more than 20 dB.  Other measures such as servo response (bandwidth), machine parts reductions, and reliability also can improve dramatically.

Repeatability Comparison

When the load is directly coupled, there is no limitation on the inertia mismatch between load and motor (Provided there is no compliance introduced in the coupling method – see blog post Reflecting” on Inertia Ratios).  The servo loop gains can now be increased significantly to provide the necessary servo stiffness to achieve excellent speed regulation to optimize product quality.
When the transmission components such as gearboxes, belts, rack and pinion, and pulleys are eliminated, the servo system becomes free of such negative factors as compliance, backlash, and component wear.  The accuracy increases, inertia-matching requirements relax, acceleration and deceleration improve, maintenance becomes unnecessary, and the product life increases by a significant degree.

What is different about direct drive motors?


Answer: 
Some slight differences in their magnetic design.

There are several factors that define the type of motion or motor that is best for an application.  Directly driving a shaft is not new technology.  Moving slow, smooth and accurate while positioning in fine increments takes the right combination of technology.  The selection of a motor, encoder, bearing system, and motor controller all contribute to the end result.

Kollmorgen Cartridge DDR Motor Family

Motors that are designed for direct drive applications tend to be optimized for lower mechanical speeds.  This is done by increasing the magnetic pole count so that the electrical frequency remains at a level for good control and efficiency while the mechanical speed of the motor is slower.  It is not uncommon to see 16, 24, 36, even 60 poles (magnets) in a motor.  A higher pole count also reduces the iron cross section required and also allows for larger through-holes (very common on direct drive motors).  Direct drive motors with large through-holes allow you to run optics, cables, and other items through the center of the motor.

Other advantages to this high pole count configuration is slightly higher torque output for a given diameter, approximately 20-30% increase.  Historically high pole count has meant reduced speed output, but recently advanced processors are allowing higher encoder frequencies.  It is not uncommon to see a direct drive motor operating at 2000-3000 rpm with the right set of bearings and the proper motor controller.  Direct drive motors tend to be shorter in axial length than diameter, this is a design choice rather then an attribute of the motor.
