LC/KC Motor Reliability Data (MTTF)

Introduction

This technical report states the MTTF for a 30cc LC & 38cc KC motor configuration.

Overview

This MTTF data has been compiled by the engineering team responsible for the LC/KC Motor. These are professionals at Danfoss, who have the authority and technical knowledge to calculate the MTTF Data for this product based on the standards set in place by both the industry and/or Danfoss.

The purpose of this document is to assist in the transfer of MTTF information for the given product from Danfoss to the appropriate party in a way which will result in a clear understanding and documentation on how we derived it. This MTTF information is provided to assist in calculating the overall MTTF of a complete or partially complete piece of machinery.

Danfoss cannot be held responsible for the suitability of these calculated MTTF values for use in the calculation of the overall machinery MTTF values. The MTTF values for the LC/KC Motor are based on a specific machine use, operating environment, and/or duty cycle as stated by the standards set in place by both the industry and/or Danfoss. This communication along with any attached Danfoss drawings, sketches, or data is transmitted in confidence.

No information stated in this document or any attachments or supplements may be reproduced or disclosed in whole or in part without written permission of Danfoss. Further, neither these documents nor any attachments are a warranty of any sort by Danfoss or a guarantee of machine suitability for its intended purpose. It remains the responsibility of the machine manufacturer to ensure overall machine functionality and overall machine safety.

We recommend consulting the functional safety cross BA team before applying the document to the customer.
