噪聲 Noise levels

噪聲值

噪聲值根據(jù) DIN EN ISO 1680 標(biāo)準(zhǔn)在噪音室測得。表面聲壓級(jí)噪聲L pfa 計(jì)算表示單位為 dB（A）。聲壓級(jí)噪聲的空間平均值是在其測量面上測得的。測量面是距離電機(jī)1米的測量包絡(luò)面。聲功率級(jí)噪聲用 L WA 來表示，單位為 dB（A）。噪音值見選型數(shù)據(jù)表，選型數(shù)據(jù)表中的噪聲值僅適用于全封閉自扇冷卻（冷卻方式：IC411）。電動(dòng)機(jī)在 50 Hz 電源供電空載運(yùn)行時(shí)，噪音容差為 +3 dB。當(dāng)在 60 Hz 電源下空載運(yùn)行時(shí)，噪音容差大約為+4 dB。

Noise levels for mains-fed operation

The noise levels are measured in accordance with DIN EN ISO 1680 in a anechoic room. It is specified as the A-valued measuring-surface sound pressure level L pfa in dB (A). This is the spatial mean value of the sound pressure levels measured on the measuring surface. The measuring surface is a cube 1 m away from the motor surface. The sound power level is also specified as L WA in dB (A). Please find the noise value in technical data table, the specified values are only valid for totally enclosed fan cooling (cooling method: IC411) motor with no load at 50 Hz with no load, and the tolerance is +3 dB. While motor operating 60 Hz with no load, the values are approximately +4dB (A) higher.

振動(dòng) Vibration

所有電動(dòng)機(jī)轉(zhuǎn)子都使用半鍵按照（標(biāo)準(zhǔn)）振動(dòng)等級(jí)進(jìn)行動(dòng)態(tài)平衡。電動(dòng)機(jī)在空載時(shí)測得振動(dòng)速度有效值不超過下表中的所列值。電機(jī)還可選擇B級(jí)振動(dòng)等級(jí)設(shè)計(jì)。

The rotors are dynamically balanced to severity grade A using a half key. Table below contains the effective vibration values for unloaded motors. Vibration grade B can be provided as option.
