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.
