冷卻與通風(fēng)
所有電動(dòng)機(jī)標(biāo)配裝有徑流（離心）式冷卻風(fēng)扇，其冷卻效能與電動(dòng)
機(jī)的旋轉(zhuǎn)方向無(wú)關(guān)（冷卻方法符合 IEC60034-6 標(biāo)準(zhǔn)的 IC411）。
對(duì)于某些應(yīng)用，可以考慮配置驅(qū)動(dòng)風(fēng)扇 ，如，
■ 電動(dòng)機(jī)在低速運(yùn)行時(shí)，推薦使用驅(qū)動(dòng)風(fēng)扇，從而使電動(dòng)機(jī)
得到有效利用；
■ 電動(dòng)機(jī)在明顯高于額定同步轉(zhuǎn)速的速度運(yùn)行時(shí)，同樣推薦選用
驅(qū)動(dòng)風(fēng)扇，這樣有助于降低電動(dòng)機(jī)噪聲。
驅(qū)動(dòng)風(fēng)扇的選件號(hào)為 F70。當(dāng)安裝驅(qū)動(dòng)風(fēng)扇時(shí)，電動(dòng)機(jī)
的長(zhǎng)度將增加 ?L。

軸承系統(tǒng)
SIMOTICS 系列超低壓電動(dòng)機(jī)標(biāo)準(zhǔn)配置深溝球軸承或角接觸球
軸承，這些軸承是密封的或可再潤(rùn)滑型的。
FS180 ~ 315 電動(dòng)機(jī)驅(qū)動(dòng)端軸承浮動(dòng)，非驅(qū)動(dòng)端軸承固定。
標(biāo)準(zhǔn)配置的軸承可以承受一定的懸臂力，關(guān)于懸臂力可以參見第
11 頁(yè)“電動(dòng)機(jī)軸驅(qū)動(dòng)端允許的zui大懸臂力”。當(dāng)電動(dòng)機(jī)軸端承
受的懸臂力較大時(shí)，可以考慮選擇增強(qiáng)懸臂力的軸承設(shè)計(jì)（選件
號(hào)： L22）。
FS180 ~ 250 范圍電動(dòng)機(jī)標(biāo)配不帶再潤(rùn)滑裝置； FS280 ~ 315 范
圍的電動(dòng)機(jī)標(biāo)配可再潤(rùn)滑軸承，并標(biāo)配再潤(rùn)滑裝置。如果需要，
FS180 ~ 250 范圍的電動(dòng)機(jī)也可選用可再潤(rùn)滑軸承和再潤(rùn)滑裝置
（選件號(hào)： L23）。
Bearing system
SIMOTICS low voltage premium efficiency motor is supplied with
the ball bearing as standard. These bearings are either of the
sealed or regreasable type.
for FS180 ~ 315, floating bearing at DE, and fixed bearing at NDE
assembled.
The standard bearing can endure a maximum cantilever force,
referred to page 11 - Permissible cantilever forces. If higher
cantilever force on the shaft required, the increased cantilever
bearing design (Option code: L22) should be considered.
As standard, FS180 ~ 250 motors are not with regreasing device,
but FS280 ~ 315 motors with regreasable bearing and regreasing
device. If necessary, FS180 ~ 250 motor can be configured with
regreasable bearing and regreasing device (Option code: L23).

軸承壽命（標(biāo)稱壽命）
軸承的標(biāo)稱額定壽命可根據(jù) ISO 281 標(biāo)準(zhǔn)規(guī)定的標(biāo)準(zhǔn)計(jì)算程序計(jì)算
出來(lái)的。如果電動(dòng)機(jī)在該樣本中所規(guī)定條件下運(yùn)行， 90 % 甚至更
高比例的軸承的運(yùn)行時(shí)間可達(dá)到標(biāo)稱壽命。通常，軸承的使用壽命
取決于軸承規(guī)格、軸承載荷、運(yùn)行條件、轉(zhuǎn)速以及潤(rùn)滑脂壽命。
當(dāng)電動(dòng)機(jī)水平安裝，且不受軸向力的情況下，電動(dòng)機(jī)的軸承壽命
至少能夠達(dá)到 40,000 小時(shí)。在承受zui大容許載荷的情況下，其壽
命也至少有 20,000 小時(shí)，這里所說的軸承壽命，指的都是電動(dòng)機(jī)
在 50 Hz 下正常運(yùn)行的情況。
Bearing life time (nominal lifetime)
The nominal bearing lifetime is defined according standardized
calculation procedures (ISO 281) and is reached or even exceeded
for 90% of the bearings when the motors are operated in
compliance with the data provide in the catalog. Generally, the
bearing lifetime is defined by the bearing size, the bearing load,
the operating condition, the speed and the grease lifetime.
The bearing lifetime of motors with horizontal type of
construction is at least 40,000 hours if there is no additional axial
loading at the coupling output and at least 20,000 hours with
the maximum admissible loads. This assumes that the motor is
operated at 50Hz.
■ 當(dāng)電動(dòng)機(jī)的運(yùn)行速度高于額定速度時(shí)，由于電動(dòng)機(jī)的振動(dòng)增
大，使得軸承受到額外的徑向力和軸向力，導(dǎo)致其壽命減少；
■ 當(dāng)環(huán)境或設(shè)備等因素引起電動(dòng)機(jī)振動(dòng)加大時(shí)，同樣軸承也會(huì)因
此受到額外的徑向力和軸向力，而導(dǎo)致其壽命減少；
■ 當(dāng)環(huán)境溫度每升高 10oC，潤(rùn)滑脂壽命以及再潤(rùn)滑時(shí)間縮短
一半。
當(dāng)電動(dòng)機(jī)在非正常的條件下運(yùn)行時(shí)，軸承的壽命會(huì)縮短。如下面
幾種情況：
When the motor runs outside of normal conditions, the bearing
life will be reduced, such as the following conditions.
■ When the motors runs beyond the rated speed, the increase of
motor vibration will result in the extra radial and axial force on
bearing. This will reduce the life of bearing;
■ When the motor vibration increase due to the environment or
other equipment, the bearing also will endure more radial and
axial force. This also will reduce the life of bearing;
■ If the coolant temperature is increased by 10 oC, the grease
lifetime and regreasing interval is halved.
