Power Savings through Energy Management using PMAC Direct Drive Servo Motor Technology

September, 2017 - Direct Drive servo motor and drive technology not only reduces an axis’ parts count, mechanical losses and often its objectionable noise; Direct drive technology also increases a machine’s efficiency, lowering operation cost for the user due to its inertia ratio, as compared to the more common mechanically advantaged multi-body axis designs. Reducing the mechanical transmission components such as gearboxes, timing belts, pulleys, cams, lead screws and so on, between the motor and its load is only part of the savings!

 Energy Management of a Servo motor: Effects of Inertia Ratio

Power Management of PMAC Servo Motors for Energy Savings: Effects of Inertia Ratio

Your first question may be what is a servomotor’s inertia ratio or mismatch (J_load : Jm or J_load/Jm)? Simply put, the inertia ratio is an important figure-of-merit for helping the machine designer consider servo controllability and risk of future potential control instabilities during the design’s initial inception. While an important figure-of-merit for all closed-loop (servo) applications, it is perhaps even more relevant for the most dynamic servo applications.

 Test the Motion without Touching the Machine image

Test the Motion without Touching the Machine

Designing and implementing a differentiated machine can be challenging, especially the motion portion.

OEMs want optimum performance, but don't want to spend a lot of time with trial-and-error testing. High-performance motion means tight tolerances and high speeds; errors in the motion application can result in machine or product damage. Ideally machine designers want to have the motion perfected before implementing it on the machine. One solution is a set-up of the actual hardware in a test environment, but this can be time consuming and adds costs to the development work. What if there is a better way?

 Selecting the Proper Cables for Your Stepper image

Selecting the Proper Cables for Your Stepper

Engineers devote a lot of time and effort designing highly efficient, reliable, and economical stepper or servo motor positioning systems. They select a motor, a controller, appropriate feedback circuits, and an amplifier to satisfy the specific motion system’s needs. Unfortunately, however, the signal and power cables connecting the components are often neglected until the project is nearing its end or worse yet, handed off to an electrician who lacks the proper training. Overlooking critical cable selection factors can deliver a system with lower than expected accuracy, frequent failures, low immunity from electromagnetic interference, and adverse affects on neighboring equipment.

The Significance of Load to Motor Inertia Mismatch

August 13, 2010- A servo system’s inertia ratio is a commonly misunderstood parameter. When dealing with stepper motors, articles and tutorials often instruct the control engineer to select a motor that will match the ratio as close to 1:1 as possible. The reason is that stepper motors are prone to de-synchronization issues and torque losses, and need to be sized to match the load to overcome these challenges...

Integrated Model-Based Machine Design with Motion

March 19, 2010 - Motion control applications are becoming increasingly challenging with higher performance, lower weight requirements, and increased functionality. Meeting these challenges often requires complex control algorithms, which call for more expertise and longer development time. In addition, the software is usually not tested until hardware prototypes are available which leads to many errors that require extensive re-coding. This design challenge is increased by the fact that manpower reductions are frequently forcing mechanical engineers to take over control system software development and testing functions that were previously handled by specialists.
