Electric Motor Systems
A number of New Zealand and overseas studies of motor systems used in industry have identified that around 80% of the electricity savings opportunities are within the system beyond the motor, rather than in the efficiency of the motor itself.
For example, with compressed air systems that typically offer electricity savings opportunities in the order of 20%, the majority of the savings come from minimizing the air leakage (and other air wastage) and from controlling how multiple compressors work together as a unified system.
EECA has two programmes under the heading of motor systems:
The Compressed Air Systems programme focuses on installing ‘best practice design and operation’ across New Zealand industry. It contains a component aimed specifically to support larger compressed air users, and another that is suited to smaller businesses.
The Other Motor Systems programme is aimed to capture the opportunities available from the wide range of other processes using electrically-powered drives, pumps and fans.
