Electric motor replacement policy: a development guide

Guidelines
13 May 2011

Motor users are inevitably faced with in-service motor failures and/or aging motors that pose risks of failure and business continuity, and consequently they need to make decisions whether to replace or repair those electric motors.

Rather than having such decisions made solely on the demands of the immediate circumstances and pressures, consistently better decisions will result from having a well-understood replacement policy in place to guide the decision-maker. The policy should be developed taking account of the criticality of the various motor uses and the economics of replacement compared to repair and/or retention of a motor.

EECA has compiled the attached guide for the development of such a policy. The purpose of the guide is to assist managers in developing site-wide policies to simplify decision-making on the replacement, compared to retention and repair, of three-phase electric motors in their businesses. The guide is not a policy document but a template for use to simplify the policy development process.

Supporting the guide is a Replacement Payback Calculator that provides a payback period estimate of the motor replacement decision.

 

In addition, EECA is offering 40% funding support (up to $2,000 per site) for businesses to establish site motor replacement policies, using the guide. This offer applies to sites with 500 kW or more of in-service electric motor capacity.
