Y/YX Series High Voltage Three Phase Asynchronous Motor
YX, YXKS and YXKK series high-efficiency high-voltage three-phase
asynchronous motor, our latest product in the 21st century, is a
new generation of high-efficiency energy-saving motor products
developed by our accumulated experience in design and manufacture
of high-voltage three-phase asynchronous motor for over 60 years
and interchangeability with ordinary Y-series highvoltage
three-phase asynchronous motor can enhance enterprise operating
efficiency and fulfill energy saving and emission reduction.
The power rating, mounting dimension and tolerance of this series
of motor comply with national standard GB/T755 Rotating electrical
machines--Rating and performance, standard of international electro
technical commission IEC34-1 Rotating electrical machines--Rating
and performance, GB/T13957 and machinery industry standards such as
JB/T12728, JB/T12730. The energy efficiency
grade shall be in accordance with 2 of GB30254-2013.
In respect of degree of protection provided by enclosure, this
series of motors are of IP23, IPW24, IP44 and IP54 as per GB /
T4942.1 and IEC34-5 Rotating Electric Machines: Degrees of
Protection provided by enclosure. Motors with other degrees of
protection can be supplied by separate agreement if requested by
users.
In respect of method of cooling, this series of motors are of IC01,
IC81W, IC611 and IC616 as per GB/T1993 and IEC34-6 Rotating
Electric Machines: Methods of Cooling. Motors with other methods of
cooling can be supplied by separate agreement if requested by
users.
In respect of type of construction and mounting arrangement, this
series of motors are of IMB3 (horizontal, with footing), which
complies with requirements in GB/T997 and IEC34-7 Rotating Electric
Machines-Classification of Types of Construction and Mounting
Arrangements and Terminal Box Position for (IM Code).
Features and advantages
1) Optimized electromagnetic design
This series of motors use finite element method to analyze
electromagnetic performance, heating, mechanical stress and
deformation; and the motors’ dimensions have been reasonably
matched and performance has been maximized to the highest level
through comprehensively optimizing not only electromagnetic design,
but also dimensions, air gap and slot combination and shape.
2) Low harmonic winding
Low harmonic winding are adopted in this series of motors, which
can reduce stator copper loss and stray loss, thus enhance
operation efficiency.
3) High-strength magnetic slot wedge
It takes a long period of research for Motor Division to solve
dropping out of slot wedge and improve the motor electrical
performance by employing high-strength magnetic slot wedge and
adopting a mature and stable slot wedge fastening process and
materials
4) Optimized ventilation cooling system
The motors use backward centrifugal fans, axial flow fans etc.,
which can maximize internal and external ventilation system,
improve cooling effect, reduce ventilation loss (esp. for
high-speed motor), lower ventilation noise and enhance efficiency.
5) Insulation system
This series of motors adopt an insulation system with various
performances comprehensively improved; voltage characteristics,
temperature characteristics, bending strength, breakdown voltage
test, heat and electrical aging tests all prove that this series
insulation system has achieved world-class level. The motors are
excellent in insulation performance, mechanical strength and
moisture resistance, since high-quality mica tape and
environment-friendly impregnating resin are adopted,
