Quality-certified motor rewinders
Motor rewinding is an important part of good motor maintenance. However, poor quality rewinding can endanger motor efficiency and reliability. To help safeguard the efficiency of New Zealand's industrial motors, EECA supports quality certification of workshops that offer motor rewinding services.
Motor rewinders may be quality certified in two ways: either to the ISO 9001 Quality Management System, or to the Telarc Motor Rewind Workshop Quality Code.
If your business relies on motors - ensure you're using a quality-certified motor rewind workshop. You can browse the list of quality-certified workshops, or look for an ISO 9001 or Telarc Motor Rewind Workshop certification logo.
If you're a motor rewind workshop - provide assurance to customers and get your work endorsed by becoming quality certified. You can do this through Telarc, or any other certification body that certifies to ISO 9001.
Poor quality rewinds can be costly
A poor quality electric motor rewind can prove expensive, leading to increased electricity use, poor reliability and increased maintenance costs.
Motor core damage is a key risk in the rewind process. A poor quality rewind may cause damage resulting in a three-fold increase in ‘core losses' (electrical losses from the motor core).
For example, a 55kW motor may lose 3 percentage points of efficiency through a poor quality rewind. If that motor then runs fully loaded for 6,000 hours per year the electricity loss could cost $1,200 per year (at 12 cents per kWh).This is before any costs resulting from reduced reliability and increased need for maintenance.
What do quality-certified rewind workshops offer?
Workshops certified to ISO 9001:2008 or the Telarc Motor Rewind Workshop Quality Code: 2009 have demonstrated through independent auditing that they have the systems in place to achieve high quality rewinding of three phase electric motors.
The Telarc Motor Rewind Workshop Quality Code was developed jointly by members of the rewind industry and Telarc SAI Limited, with support from the Electricity Commission.
Engaging a quality-certified workshop provides assurance that you're dealing with a supplier who is committed to quality motor rewinds. It is the easiest way to ensure you'll get the best value from your rewind investment.
