ESI’s End-to-End Design, Analysis & Support

Committed To More Than Simply Manufacturing Hardware!

Our servo control systems are designed to be used in high-demand applications, and often demand a long lifespan with years of dependable use. Unlike many manufacturers in the industry we have placed special attention on the engineering, design, and analysis portion of the manufacturing process, along with the documentation and support that follows.

The hardware represents a big portion of our service, but our clients deserve a more comprehensive partner, and we offer the following services for every servo drive design!

Complete Product Documentation

One of the most important aspects of design longevity is the associated documentation, and this is something we take very seriously. As we design and integrate your servo drive we keep detailed records, diagrams, and pertinent documents related to the system which you have full access to. Our documentation policy ensures that you have complete access to quality information regarding your servo drive.

Design Reviews & Analysis Before Delivery

The final performance of your servo drive will ultimately depend on many complex factors. Our goal is to analyze these factors, and identify opportunities to increase efficiency and create an ideal solution for your application. Our engineers will carefully review the initial designs prior to delivery, adding modifications and suggestions when applicable. We won’t simply build you a sub-par servo drive, we will work closely with you to reduce cost and increase performance!

‐ Engineering Design Reviews Include:
  • System Requirements Review (SRS)
  • Preliminary Design Review (PDR)
  • Critical Design Review (CDR)
  • Manufacturing Readiness Review (MRR)
  • Test Readiness Review (TRR)
  • Flight Readiness Review (FLR)

Our Approach To Obsolescence Management

As technology and manufacturing progress, hardware and software of any kind will eventually become obsolete. ESI Motion has taken measures to keep our servo drives flexible to give them increased lifespan and adaptability. Our engineers have carefully balanced specific modular components without sacrificing durability, allowing us to manufacture drives with impressive service life expectations.

‐ Our approach to obsolescence management includes:
  • Design for Obsolescence
  • Obsolescence Management Plan
  • Obsolescence Reviews
  • Proactive Monitoring & Updates

Our long-term design focus fits hand-in-hand with the comprehensive design phase, and our engineers will actively plan for your servo drive to provide many years of dependable service!
