Motor Rewind Workshop Quality Scheme

The adoption of workshop quality standards by the motor rewind industry is considered important to achieving consistently higher quality motor rewinds, and thereby protecting the electrical efficiency of the New Zealand motor stock.

In November 2009, Telarc Limited and the Electricity Commission launched a Motor Rewind Workshop Quality Scheme that includes a Rewind Workshop Quality Code^† and incentives for rewinders to develop systems that conform to that Code.

The Code covers people skills, equipment and process requirements and management systems. Rewinders certified as meeting the Code’s requirements will have tangible evidence of their ability to provide high quality motor repairs and rewinds to their motor user clients, and thereby maintain the cost efficiency of their clients’ motor systems.

Smart businesses use quality-certified motor rewind workshops.

How do you judge the quality of your rewound electric motor?

The cost of a poor quality rewind

A poor quality electric motor rewind can cost a business dearly. Left in that state for the rest of its life it will increase electricity costs and possibly cause reliability issues and increased maintenance costs.

Motor core damage is a key risk in the rewind process, and it is not difficult for a poorly controlled process to cause damage that may increase the ‘core losses’ (electrical losses from core damage) three-fold, compared to a high quality rewinding process.

Quantifying that loss of efficiency, a 3 percentage point loss of efficiency for a 55 kW motor running fully loaded for 6000 hours per year (using an electricity cost of 12 cents per kWh) will increase the electricity costs by around $1200 every year.

Add to this the risks from reduced reliability and increased maintenance costs, and there is considerable incentive to seek out quality rewind workshops to do your motor repairs.

What does a quality-certified motor rewind workshop offer?

Workshops certified to the Telarc Motor Rewind Workshop Quality Code:2009 have demonstrated through an audit of their businesses that they have the skills, equipment and processes in place to achieve high quality rewinding of three phase induction motors.

The Code has been developed based on internationally accepted standards in conjunction with representatives of the New Zealand motor rewind industry.

Engaging a quality-certified motor rewind workshop provides you with the assurance of dealing with a supplier that has a demonstrable commitment to quality motor rewinds and has been independently assessed as conforming to the Code. It is the best means of being assured of getting best value out of your rewind investment.
