高效電機(jī)節(jié)能，是不可否認(rèn)的事實(shí)。但實(shí)際應(yīng)用中有網(wǎng)友留言，對(duì)高效電機(jī)持一種相對(duì)抗拒的態(tài)度，PFSA103B EXCYM322001-EN主要表現(xiàn)為兩種傾向：
一種：成本高
PFSA103B EXCYM322001-EN不少電機(jī)使用者很在意電機(jī)的采購(gòu)價(jià)格，在權(quán)衡更換電機(jī)與節(jié)能效果的投資情況；特別是PFSA103B EXCYM322001-EN 對(duì)于電機(jī)使用頻度不高的情況，大多數(shù)采用被動(dòng)態(tài)度；當(dāng)然，對(duì)于電機(jī)使用頻度較高、用電量較大的場(chǎng)合，高效電機(jī)的整體節(jié)能效果非常明顯，電機(jī)使用者對(duì)于高效電機(jī)也有較大的采購(gòu)興趣。
二種：實(shí)際節(jié)能效果不明顯
PFSA103B EXCYM322001-EN一位網(wǎng)友留言，某市在2009-2011做過(guò)用電企業(yè)的電平衡檢測(cè)，1100多家企業(yè)，每年累計(jì)運(yùn)行時(shí)間在3000小時(shí)以上的電機(jī)只占到20%左右，而且還不一定是接近額定負(fù)載。PFSA103B EXCYM322001-EN 不少的電機(jī)在運(yùn)行時(shí)負(fù)載率不足，直接影響到高效電機(jī)的節(jié)能效果發(fā)揮。按照電機(jī)的工作原理，當(dāng)負(fù)載達(dá)到或接近其額定值時(shí)，電機(jī)的效率高，而輕載運(yùn)行的電機(jī)并不能體現(xiàn)出其節(jié)能效果。
The fact that efficient motors save energy is undeniable. However, in practical applications, some netizens have left comments expressing a relatively resistant attitude towards high-efficiency motors. PFSA103B EXCYM322001-EN mainly exhibits two tendencies:
The first type: high cost
PFSA103B EXCYM322001-EN: Many motor users are very concerned about the purchase price of the motor, and are weighing the investment situation between replacing the motor and energy-saving effects; Especially for situations where the frequency of motor usage is not high, PFSA103B EXCYM322001-EN mostly adopts a passive attitude; Of course, for situations where motors are frequently used and consume a large amount of electricity, the overall energy-saving effect of high-efficiency motors is very obvious, and motor users also have a great interest in purchasing high-efficiency motors.
Second option: The actual energy-saving effect is not significant
PFSA103B EXCYM322001-EN, a netizen left a message stating that a certain city conducted electricity balance testing for electricity consuming enterprises from 2009 to 2011. Among more than 1100 enterprises, only about 20% of the motors have accumulated operating time of over 3000 hours per year, and they may not necessarily be close to the rated load. Many motors in PFSA103B EXCYM322001-EN have insufficient load rates during operation, which directly affects the energy-saving effect of high-efficiency motors. According to the working principle of the motor, the efficiency of the motor is highest when the load reaches or approaches its rated value, while the energy-saving effect of the motor cannot be reflected in light load operation.
