New efficiency oriented drives for high end fans

摘要

High efficiency motors and drives for fans. Energy saving, some aspects on high efficiency electrical machines, experiences in efficiency for electrical drives over the past 15 years Special integrated external rotor motors for network and frequency inverter supply, real efficient new fans applications. Aluminium and copper cage rotor induction motors to meet the needs of air conditioning control and total system energy saving, some comparison and selection guidelines towards most adequate systems. New die cast copper cage external rotor motors as robust new high efficiency motors for fans, actual and future applications. Handling with efficiency to cost rates, payback and benefits for customers and world climate.
