g) Superior starting features.
h) High quality of motor guaranteed high operational reliability.
i) High effciency, energy saving, safety and environmental protection.
Today, anyone who purchases new motor or hopes to make heavy repair for the original motor, careful
calculation must be taken: if the chosen of energy-saving motor would worth more? Generally speaking, it is
wise of user to select energy-saving motor, because it is the most effective measure to fall down the price of
electric energy. When analysing the expenses of motor, typical running time is 3000h per year, total running
time is 10 years.The amount expenses of purchase, installation, service and maintenance are 3% of the total
expense. The operating expense is almost the electric energy expense, but it excesses 97% of the total expense.
If the electric energy expenses can be saved, that you are economical only at the motor is running. Although
the first cost of the motor is high, it can be returned in a year. However,we can not only see the commercial
value of the calculation above mentioned.
The motor consumes 60% industry electric energy, a research indicated that the saving potential of driven
system is about 20000 MW.h per year, it is equivalent to the output of eight coal fired power plant; more than
that, it still discharge oxycarbide of 1.1 million tons. This means that the environment protection is benefit
from every energy-saving motor.
The efficiency of YB3 series of motors is 1% 2% higher than YB2 series of motors in average ratio, for
the specific condition, see fig2. the saved electric energy cost of efficiency is much higher than the increased
cost.
Fig.1 The efficiency comparison value between YB3 and YB2 series of motors
Take 15kW-4P as an example, to compare with YB3 and YB2, the station of employed raw material and
energy saving are as following table:

and general quality assurance.
From the above table, we find that YB3 160L-4 15Kw is 27% higher than YB2 160L-4 15kW on weight
of copper, and 13.5% higher on weight of silicon steel plate, 86% higher on weight of aluminum. According to
current price ( enamel wire: 35000yuan/ton, aluminum:14500yuan/ton, B50AH470 silicon steel plate:
8000yuan/ton), effective material increases by 212yuan. Comparing to YB2 series of motors, the increased
cost can be recovered from the saved electricity cost, and the cost for operating after the recovery period is net
income. The saved electric energy per year see fig.3, the recovery period see fig.4.
Calculation of the recovery period can be as follows
T —Recovery period h
C —the increased cost for selecting this range of motors (yuan)
—The price of electric energy, 1kw·H 0.65yuan

5 Environment and area defination
5.1 Explosive gas atmospheres
Explosive gas atmospheres is that gas steam or haze combustible and air form mixture under atmospheric
condition, after firing, combustion transfer to unburned mixture.
Hazardous location is that explosive gas atmospheres appears or expected appears amount which is
enough to take special preventive measures for construction installation and operation of electrical
apparatus.According to the frequency and duration of explosive gas atmospheres, hazardous location is
divided into 0 zone 1 zone 2 zone.
5.2 Temperature class
Electrical apparatus for explosive gas atmospheres according to its maximum surface temperature divided
into the temperature class. The maximum surface temperature for electrical apparatus must be lower than
ignition temperature of an explosive gas atmosphere. To choose electrical apparatus according to maximum
surface temperature, there are six temperature classes in total. The temperature class see table 3.

c) Dimension of sealing ring (external diameter of entry cable for users)Cables should be selected
correctly according to rated current and operation condition of the motors. The diameter of the cable led into
the terminal box should be in accordance with that of the hole of seal ring. Seal ring for cabtyre cable and
armor cabtyre cable have many concentric grooves and the inner diameter of the seal ring can be selected
according to the diameter of the cable, It should be ensured that there is no clearance between the seal ring and
the cable, the seal ring and the base of the terminal box after the cable gland is pressed. For seal ring, see fig.20,
the main dimension see table 10.

14.2 The max. radial force ( to the drive system of belt pulley)
The max. radial force: the max. permissible radial force F (in N) of radial load is based on the following conditions: the action
line (the centre of belt pulley) of load capacity must be within the free axis length (the length is X) , the X length (mm) is the
distance between shaft shoulder and F action line. Thus X length is the total length of shaft extension, the max. radial force at
50HZ, for the basic structure, see table 13.

16 Ordering information
Please specify the motor type, output, synchronous speed, voltage, frequency mounting arrangement,
flame-proof class, and type of cable entry(cabtyre cable when there’s no specify) and outgoing (one bucket
and six terminals or two buckets and six terminals) of terminal box, etc.
If the motor with 15kw 4-pole 380V IMB3 mounted flame-proof markings of ExdIIBT4 IP55
cabtype cable and two bucket and six terminals are required, it should be marked as follow:
YB3 160L-4P 15kW 380V 50Hz IMB3 ExdIIBT4 IP55 two buckets and six terminals
The noise class degree of protection bearing grease filling-draining construction and direction of
rotation should be noted in the contract.
