China Simo YE3 Low Voltage Three Phase AC High Efficiency Induction Motor

Brief Introduction

The YE3 series (frame size H80~450) low voltage three
phase asynchronous motor is a high efficiency electric motor with fully
enclosed structure and self ventilated cooling fan. The motor frame generally
adopts high-strengthen gray iron, and coil adopts fine anti-corrosive cooper
wire.   It is widely used in general industries like machinery, transport, printing, agricultural and so on.

Main Technical Parameters

YE3 introduction

YE3
series of motors is an ultra-efficient and energy-saving three-phase
asynchronous motor independently developed by our company. The cooling method
is 1C411. The motor performance meets GB/T 755 “Rating and Performance of
Rotating Motors”, and the efficiency value meets the Level ONE energy
efficiency standard of GB18613-2020. , and is consistent with IE3 in the
international standard IEC60034-30 “Energy Efficiency Classification of
Single-speed Three-Phase Cage Induction Motors”. This series of products
can completely replace Y series, YGM series, YGM2 series, YE2 series
low-voltage three-phase asynchronous motors.

The
motor shell is made of high-strength gray cast iron, and the coils are made of
high-quality corrosion-resistant copper wire. The protection grade is IP55,
which complies with GB/T 4942.1 and IEC 60034-5. The installation dimensions
comply with the IEC 60072 international standard and the national standard GB/T
4772.1. The cooling method is IC411, and is suitable for continuous working
system (S1) operation. It has the characteristics of low loss, high efficiency,
compact structure, smooth operation, low vibration, low noise, long service
life, easy use and maintenance, etc. It can be widely used in machine tools,
water pumps, fans, compressors, reducers, and can also be used for
transportation, mixing, printing, agricultural machinery, food and other types
of mechanical transmission equipment.

The
motor has one shaft extension, which can be made into a double shaft extension
according to user needs. The second shaft extension can also transmit rated
power, but it can only be driven by a coupling.

According
to user needs, other motors with power, voltage, frequency, humid tropical zone
type (TH), protection level, etc. can also be supplied.

Operating Condition

Ambient
Temperature: -15℃~+40℃

Altitude:≤1000m

Note:
When the ambient temperature altitude are different with above regulations, the
above conditions can be modified according to GB/T 755 regulations.

Humidity:Average
monthly peak relative humidity is 90%.

Mounting Type

Motor
mounting type is accord with regulations of GB/T 997 Electric Motor Structure
AND Mounting Type Code, as below chart:

Note: For
IMV1 mounting type, no rain caps for motors of H80~H160 variable frequency
motors and with rain caps for H180~H355.

Bearing

Bearings
are relatively easy-to-wear parts among motor products, and how they are used
and maintained is closely related to the life of bearings. Bearings should be
regularly maintained and grease should be regularly replaced. If the damaged
bearings are not replaced in time, the motor may easily be destroyed. Under the
load within the allowable range, the bearing design life of the motor should
meet the requirements of H80­H355:
2-pole motor for 20000 hours. 30,000 hours for 4-pole, 6-pole, 8-pole and 10-pole
motors (which refers to the life of motor under normal running conditions at
50Hz and under normal maintenance as required).

Motors
adopt rolling bearing and motors of H80~450 are equipped with deep groove ball
bearings or angular contact bearings as per standard. These bearings are sealed
or re-lubricated. Motors in H80-132 adopt fully enclosed maintenance-free
bearings and motors in H160-450 adopt open & re-lubricated bearings.

Terminal Box

The
position of the motor main power terminal box is at the top by default. The box
opening is towards the right, and the terminal box can be mounted horizontally
by rotating 180°. The terminal box connector is
designed as per national standards. According to the motor current and the
conditions of usage, the cable should be selected correctly. The diameter of
the cable entry of the terminal box should match the diameter of the seal ring.

Wiring

Y connection
is adapted to motors of 3kw or 3kw below. and Δ
connection is adapted to motors of 3kw or 3kw above, connection instructions
seen as Figure 1

Application

YE3 motor is commonly used to drive water pumps, fans,
compressors, conveyors and other transmission machinery in energy conservation
and environmental protection transformation projects, national water
conservancy projects, etc.
