EFF1 motor is designed to run motor than 6000 Hours of annual runtime. Example. A 20 HP 4poles motor has the efficiency more than 91.3% means such motor is called EFF1 class motor.

The EFF has 3 classes, i.e. EFF1, EFF2 and EFF3 respectively. EFF1 is the most energy efficient, while EFF3 is the least energy efficient. In other words, the lower class number represents the higher motor efficiency. The testing method is based on IEC 60034-2-1:1996 – Standard methods for determining losses and efficiency from tests

The motors are the main power of industry, which conform to CNS14400 energy efficiency standard, American EPAct or European EFF1 efficiency and save electricity 2%~8% than general efficiency motors. The prices of high efficiency motors …

2012年3月28日 · IEC 60034 Efficiency Limits IEC 60034-30 defines three efficiency classes for of single speed, three phase, cage induction motors. IE1 - Standard efficiency (efficiency levels roughly equivalent to EFF2) IE2 - High efficiency (efficiency levels roughly equivalent to EFF1, identical to EPAct in USA)

EFF1 scheme now in effect, Brook Crompton have developed a new range of premium efficiency motors. As a result, we can offer EFF1 motors across the whole range, relevant to this scheme 1.1 to 90 kW, 2 and 4 pole.

IEC 60034-30-1: 2014 defines four IE (International Efficiency) efficiency classes of single speed, electric motors that are rated to IEC 60034-1 or IEC 60079-0 (explosive atmospheres) and designed for operation on sinusoidal voltage.

End users should specify high effi ciency motors to machines suppliers and OEMs. The European effi ciency classifi cation scheme is a useful tool for identifying effi cient motors. How does the scheme work? The scheme divides motors into three effi ciency levels, EFF1 - EFF3, with EFF1 being the highest effi ciency level.

Motor Frame Size EFF class: motor fram size is very important mechanical data; it is very useful for motor alignment (to couple with the load). It contains motor’s the core size and height from ground point to shaft center. Basically three type of motor core will come 1. S => shorter core, 2. M => medium core, 3. L ...
