Ⅳ Construction features
Y2 Series of High-Voltage Compact type Three-phase Induction Motor is the latest-generation motor
with high efficiency, energy saving and environmental protecting advantages. It is designed and
manufactured on the basis of experiences of years of manufacturing motors, through the analysis of
construction field, electromagnetic field, fluid field and compound field by large finite element analysis,
and through the principle of double circulated cooling and ventilating system. This series of motors have
advantages of small volume, light weight, compact conformation, good appearance and smooth lines etc.
1.
Cooling air path, frame and end shield
Y2 series of motors has two independent cooling air paths: internal cooling air path and
external cooling air path (see Fig.2), most of the loss heat transmit from stator core to motor
frame, and then bring away by external cooling air, the rest loss heat transmit to motor frame
through internal cooling circuit and take away by external cooling air.
Fig. 2
The motor frame use quadrature distributed total cooling fin casting frame, between
cooling fins use nonisometric distribution and discentric circle combination method, 4 axial
air duct are provided at 45°direction. Because of the motor frame has reduced scale, outer
cooling air from non-driving end can reach to driving end more effectively through cooling
fins, so as to achieve the best cooling effect. The terminal box is located at upper motor side
where air duct has placed in order to not influence heat dissipation and the flowing of cooling
air. The frame inner surface around stator winding end provided with heat absorption rib.
Frame enough large area of dissipation with rib type construction guaranteed powerful heat
sinking ability.
Two lifting rings are opposite angle mounted on the air duct (the angle of lifting rings can
be random adjusted) to make the motor hoisting more convenient.
The end shield of driving end and non-driving end has the same structure; heat sinking rib
is provided for inner and outer of end shield to enhance the end shield stiffness and heat
7
0EE.138.176-2007
sinking ability. High strength casting iron motor frame and end shield ensured the motor has
high stability.
2 Low noise fan
On the precondition of the cooling effect has been satisfied, the fan and fan cover use
streamline design construction, so as to improve fan efficiency and reduce fan noise.
External fan: 2 poles: propeller type axial fans (unidirectional rotation); shaft height
H355-H400, 4 poles and above motor use convex centrifugal fan and can be bidirectional
rotated. H450 and above, 4 poles motor use backward tilting type centrifugal fan, only
suitable for one direction of rotation; motors with other poles use convex centrifugal fan and
suitable for both directions.
Internal fan: Radial centrifugal fan (can be bidirectional rotated).
3 Stator
The motor has a laminated core first compressed and secured before it is fitted into the
frame and then pressed into the machined frame.The stator windings are class F insulated,
anticorona treatment(10kV),the ends of windings are boneded and fixed firmly, and the
windings are vacuum pressure impregnated with solventless varnish. Therefore, the motors
have good and reliable insulating performance, higher mechanical strength, long service
life,as well as higher moisture-resistance, corrosion resistance and anticorona ability.
4
Rotor
The further aim of this series of motors is cast aluminum rotor technology, which has already proved
to be successful in millions of low-voltage and high-voltage motors and then popularized to large capacity
motor. The rotor busbar and short circuit ring casting into an integral part. This technology ensured the
solidity of the structure and the unique stability of the cast rotor. Use centrifugal cast aluminum technique
pouring the liquid state aluminum into rotor lamination core slot, the mould is pouring at one shot, the short
circuit ring and the busbar are pouring at the same time.
5
Bearing
There are two kinds of bearings: rolling bearings and sleeve bearings. Usually the motor use rolling
bearings, sleeve bearings are used for motors which the service conditions (depending on rotating speed,
load and operating conditions) exceed the limit value.
The DE and NDE bearings for standard designed motor H500-2 (3kV、6kV、10kV) and
H560-2（3kV、6kV、10kV）are end-shield type spherical sleeve bearings, forced lubrication
and the insulation treatment is provided for NDE. Permit axial play at free state is ±5mm, in
this case the motor rotor and shaft system must be axial located by “caging device” on driven
8
0EE.138.176-2007
equipment. H500-2(10kV) also has rolling bearings; other motors use rolling bearings and
have oil inlet and outlet device（without shutdown the motor）, can fill up the lubrication
grease and discharge the waste grease during motor operation.
6
Terminal box
According to the different explosion-proof requirement, the terminal box for main power
supply is increased-safety type steel plate tension terminal box, and has the advantage of
beautiful appearance, lower weight, suitable for motors with 3kV, 6kV and 10kV voltage, and
high generalization degree.
Standard designed motor have two terminal boxes, namely main terminal box and
auxiliary terminal box. The main terminal box can be mounted at four different positions on
motor frame ventilating slot in order to meet the different connection requirement at site. If
there is no special requirement, the main terminal box should located at DE right upper side
(viewed from motor shaft extension end), cable inlet from bottom. The auxiliary terminal
box is located at NDE right upper side (viewed from motor shaft extension end), cable inlet
from bottom.
7
Monitoring and protection
Standard designed motors provided with these monitoring and protection devices: stator
winding temperature detector platinum resistance PT100, bearing temperature detector
platinum resistance PT100 and anti-condensation space heater. All the connecting wire of
temperature detector and heater are connected into the connecting terminals of auxiliary
terminal box.
