Y，YKS，YKK高压型三相异步电动机

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.

当然可以。高压型三相异步电动机，通常是指具有Y、YKS和YKK等型号的电机，它们属于电力传动设备中常见的种类之一。 1. **Y 型三相异步电动机** (Y系列)：这是一种最常见的三相鼠笼式异步电动机结构，其中 "Y" 代表星形连接（英文为"star-connected")，特点是初级绕组以星形方式联接，次级绕组在定子空间形成旋转磁场，转子通过电磁感应产生转矩，适用于一般工业与民用场合的驱动设备。 2. **YKS 型高压三相异步电动机** ("YK" 可能是某个品牌的缩写加上 "S"，这里的"S"可能表示某种特殊设计或改进)，它是在Y型的基础上增加了高压运行的能力，例如耐受更高的电压等级，通常用于需要更高电压操作的行业如冶金、化工、矿山等领域，或者在大型机械装备中作为动力源。 3. **YKK 型高压三相异步电动机**："KK"通常是某个品牌或技术特征的进一步扩展，这里可能是对Y型基础上进行加强或者优化设计，比如采用了更为高效或者耐用的材料、特殊冷却系统、高强度绝缘等级等特性，使其能够在高压环境下更稳定、高效地工作，常见于大型发电厂、船舶推进、地铁车辆牵引等要求严苛的场合。 总结来说，这三种型号都是高压型三相异步电动机的不同类型，各自针对不同的应用环境和需求进行了专门的设计与优化。
