UL Motor Efficiency Standard
The UL efficiency standard and the test method base on UL1004-1. The tested motor should meet both minimum efficiency requirements and the nominal efficiency. The other standard that is commonly used is the IEC standard. According to IEC 60034-30-1 Standard, the efficiency level of three-phase induction motor has been defined as IE1 (Standard), IE2 (High), IE3 (Premium) and IE4 (Super Premium). Compared to IE1 motor, the materials and design are both been upgraded in IE3 motor, which becomes more durable and energy-saving.
Energy Saving Example
10 pieces of IE3 motors with specification of 11kW 4P 220V 60HZ, run 12 hours a day for 5 years (each year run 365 days). The electric fee is NT$5/kWh (USD $0.17 /kWh)
Change motor from IE1 to IE3, USD$1900 will be saved after five years
