Y，YKS，YKK高壓型三相異步電動機

General
Y, YKS and YKK ranges of high - voltage three - phase
induction motors are optimum series products which are de-
signed and manufactured by our company using advanced tech-
nique at home and abroad, in combination with tens - year
practical experiment of our company on production of high-
voltage motors , and are renewing and generation - changing
products of former JS and JSQ series high - voltage motors .
They have advantages of compact construction, light weight,
high efficiency, energy - saving, low noise, small vibration, high
reliability, long service life , easy mounting and maintenance,
etc., as compared with former JS and JSQ series products.
This range of motors are suitable for driving the general-
purpose machineries such as all kinds of ventilators, compressors,
water pumps, crushers, cutting machine tools and transportation
machineries, etc . as well as other machineries , and act as a
motive power machine in all kinds of industrial and mining
establishments such as mining, machinery, petroleum, and chemi-
cal industries as well as the power plant , etc. If the motors are
used to drive the blower, the coal - grinder, the rolling mill, the
lifting winch and the belt conveyer, the relevant technical
information should be supplied when ordering, and the techni-
cal agreement should be signed, which is taken as a basis of
special design of motors , thus ensuring the motor to operate
reliably.
The motors are class F insulated, but thermally utilized
according to class B . Rated frequency is 50Hz, rated voltage is
3kV, 6kV , or 10kV , and the motors of 60Hz and other voltages
can also be available on request of ordering.
The basic mounting arrangement of motors of this range is
of the horizontally foot - mounted construction (IMB3).
Y is a basic range of motors. YKS and YKK ranges are
series products derived according to different methods of cool-
ing and degrees of protection.
The features of YKS and YKK ranges of products are
shown in the table 1.
This range of motors conform to the relevant IEC stan-
dards and GB755 Rotating Electrical Machines - Ratings and
Performances.Table 1

Features of construction
The motors are of box - section construction, the frame is
welded into box - section using steel plate, and hence the weight
of motors is light and rigidity is good. Two sides and top of the
frame are all provided with the windows, which, on the one
hand, is convenient to maintain and take care of motors, and, on
the other hand, can mount different coolers on the top of frame,
thus being capable of deriving the motors with different methods
of cooling and different degrees of protection.
The motor has a laminated core which is first compressed
and secured before it is fitted into the frame and then pressed
into the machined frame, the motors have good insulating
performance, higher mechanical strength, higher moisture - resis-
tance and longer service life.
The squirrel - cage rotors are of both cast aluminum con-
struction and copper bar construction. The rotors are manufac-
tured using advanced & reliable cast - aluminum and welding
process, and are well balanced. Therefore, the motors operate
smoothly and reliably.
Rolling bearings or sleeve bearings are used for the motors,
depending on the power and speed of motors. Degree of protec-
tion is IP44 or IP54. The rolling bearings are provided with
grease - filling and - draining devices without shutdown.The main terminal box is located at the right side of the
motor ( viewed from the shaft extension ), and can also be
located at the left side on user request. Interior and exterior of
the terminal box all are provided with separate earthing terminals.
On user request, the stator winding and the bearing can be
provided with temperature - measuring devices so as to be conve-
nient to observe them in site and monitor them in remote
distance, thus ensuring the motor to operate safely and reliably.

當然可以。高壓型三相異步電動機，通常是指具有Y、YKS和YKK等型號的電機，它們屬于電力傳動設備中常見的種類之一。 1. **Y 型三相異步電動機** (Y系列)：這是一種最常見的三相鼠籠式異步電動機結構，其中 "Y" 代表星形連接（英文為"star-connected")，特點是初級繞組以星形方式聯(lián)接，次級繞組在定子空間形成旋轉磁場，轉子通過電磁感應產生轉矩，適用于一般工業(yè)與民用場合的驅動設備。 2. **YKS 型高壓三相異步電動機** ("YK" 可能是某個品牌的縮寫加上 "S"，這里的"S"可能表示某種特殊設計或改進)，它是在Y型的基礎上增加了高壓運行的能力，例如耐受更高的電壓等級，通常用于需要更高電壓操作的行業(yè)如冶金、化工、礦山等領域，或者在大型機械裝備中作為動力源。 3. **YKK 型高壓三相異步電動機**："KK"通常是某個品牌或技術特征的進一步擴展，這里可能是對Y型基礎上進行加強或者優(yōu)化設計，比如采用了更為高效或者耐用的材料、特殊冷卻系統(tǒng)、高強度絕緣等級等特性，使其能夠在高壓環(huán)境下更穩(wěn)定、高效地工作，常見于大型發(fā)電廠、船舶推進、地鐵車輛牽引等要求嚴苛的場合。 總結來說，這三種型號都是高壓型三相異步電動機的不同類型，各自針對不同的應用環(huán)境和需求進行了專門的設計與優(yōu)化。
