1. Circumstance of use
1.1 Applicable: On weather deck or similar condition where the ambient temperature is
-25℃~+45℃; the application altitude not exceed 1000m..
1.2 The initial cooling water temperature shall be no higher than +32℃.
1.3 Relative humidity of wet month shall be no higher than 95%, and condensation is allowable.
1.4 Inclination and rocking: trimming 5°(emergency motor 10°) ; pitching 10°(emergency motor
10°); heeling 15°(emergency motor 22.5°); rolling 22.5.
1.5 The motor can be applied in the circumstance where contains inammable gases, and harmful
gases or steam (except for the special purpose motor).
1.6 Motor can be started at full voltage or reduced voltage. Starting current is 3.3-8.0 times rated
current if it starts with full voltage. As torque is proportional to voltage square, the torque will be
reduced when the motor is started at reduced voltage. So if the static load is fairly large, the motor can
be only started with full voltage.
1.7 Keep the motor clean and in good ventilation.
1.8 There are two kinds of connections of the motor. Motor less than 4kw is of Y connection, 4kw
and above are △connection. Ensure that all the terminals are connected as the diagram.
·Please read the manual carefully before use
·Please keep it properly

2. Installation & operation
Warning!
Be careful when handing motor!
Strong falling, bumping or shaking will damage bearing and other elements.
Make sure the eyebolt is tightened before lifting up the motor.
2.1 Inspection before installation
Check and make sure the appearance of the motor is in good order. Check and ensure that the
motor nameplate is consistent with the actual requirement.
Rotate the motor shaft gently to see whether its rotation exible and quick or not.
Ensure that all parts have been connected correctly and tightly.
Open the terminal box cover and measure the insulation resistance of the winding with 500v meg-
ohmmeter, the value should be no less than 5 MΩ.
Note If you have any question during inspection, please consult technician or contact us.
2.2 Installation
Warning!
1. Voltage uctuation of the supplied power should not exceed the range 95%~105%
of the rated voltage.
2. Connect the motor according to connection diagram strictly
3. Connect grounding wire safely.
4. Remove the sleeve and key on the shaft end before power up, keep body and
clothes far away from rotating parts of motor.
5. Stop the motor immediately if any abnormal problem occurs.
• Installation should be performed by technician.
• Coupling, spur gear and belt pulley are allowed to be used for transmission.
• The shaft center of the motor must keeps consisting with that of the driven machine.
• If motor has mounting feet, ensure that the mounting face should be at and solid.

8
• The core of the power line cable should be connected between the two gasket, ensure there is
no bur. Check and ensure there is no damage on the cable when put through the cable entry of the
terminal box, the cable should be xed by a blanking plate and bow washer to prevent moving.
• To t different voltage different connection mode (by changing its connection straps) should be
adopted (see the connection diagram on terminal box cover).
• Motor will rotate clockwise viewed from driving shaft end if the terminal U,V,W is connected
to power line phase sequence A, B, C. Otherwise the motor will rotate anti-clockwise. Provided the
reverse rotation is need, any two of the three U, V, W can be interchanged.
•Ensure the internal & external grounding bolts have been safely grounded.
•After checking all the connections, turn on power for no-load operation test for 30-40min, and
then put into with-load operation.
3. Maintenance
Warning!
1. Non-full phase operation is prohibited.
2. Repeated starting will cause overheat of motor, or even damage motor.(In
particular, start with the load directly).
3. Avoid overload. Overload will cause overheat, and overheating will shorten the
insulation life. As a result, it will reduce motor reliability.
3.1 Check and clean the motor periodically, make sure no dust cover on the motor. Do not inject
water to clean the motor.
3.2 Bearing temperature should not exceed 95 ℃(Thermometer method) during operation. The
bearing should be inspected every 2500h (about half a year) operation. The bearing grease should be
replaced immediately if the grease is found to be spoiled. It’s proper to ll 1/3~1/2 capacity of the
bearing chamber with lubrication grease. No.3 Lithium-base lubricating grease is recommended.
Bearing size is listed in the table below:

Note：When changing bearing, take the nameplate of the actually assembled bearing as standard.
3.3 No inner and outer bearing cover for H80-132 frame size motor. Disassemble the motor as the
following order: rstly remove fan cover, and V-seal ring on the drive end, secondly remove the bolts
on front end cover and rear end cover, and lastly take out the rotor together with the front end cover
and cooling fan.
3.4 Motor must be dried before use if the motor has been affected with damp by means of drying
in the oven or short-circuit current. The temperature should be increased gradually but not exceed
145℃if dried in the oven. And when the motor dried by short-circuit method, it should be connected
as short circuit whose input current is 0.6-0.8 times rated current. However the short-circuit method is
not suitable if the motor is heavily damped, since it may cause the electrolysis.
3.5 If the winding needs to be replaced, the original winding’s type, dimensions, diameter and
turns of coil should be recorded. Arbitrarily changing of winding will decrease the performance of the
motor, and even to damage the motor.
3.6 Any maintenance or replacement of its components must be done by professional people.
3.7 The motor need to be periodically inspected according to its actual operation, overhaul at least
once a year.
3.8 Grease may harden in long-time idling. When abnormal sounds occur at the beginning of
operation, the motor need to be operated without load for half an hour so as to soften grease and
restore its function.
4. Failures & causes
Check motors frequently in order to remove the possible failure in advance. The common failures
are as follows:
4.1 Mechanical fault:
• Bearing overheating: lack of grease, dirty grease, low quality grease, water intrusion, oil ring

10
stuck, surface fault of bushing, narrow distance between shaft and bushings, excessive pressure on
shaft neck and axial current and so on.
·Leakage of oil or grease: too much grease in bearing, grease of bad quality or incorrect viscosity,
unbalanced pressure between bearing oil container and the bearing cover.
•Strong vibration: inconsistent center line of the shaft between motor and the driven machine,
incorrect mounting position on base plate, shaft bending, bad cooperation of coupling, unbalance
of pulley or coupling, large space between shaft journal and bushing, broken rotor bar, vibration of
stator core, uneven surface of base plate, inadequate rigidity of base plate, similar or same vibration
cycle of the motor and the base plate, rough belt coupling, incorrect position of the belt coupling, poor
operation of the transmission or the collision of the motor, etc.
•Eccentric of rotor: loose bushing, bearing displacement, the deformation of rotor and stator, bend
of the shaft and poor balance of the rotor.
4.2 Electrical Fault：
•Abnormal starting: incorrect connection, open circuit, incorrect voltage, too high load torque and
too high static torque, starting device failure and so on.
• Motor overheating: much higher or lower than rated voltage, overload, lack of cooling air, too
high ambient temperature, short circuit or uncleanness of the motor, etc.
•Insulation damage: high working voltage, damage from corrosive gases like acid gas, alkaline gas
and chlorine, too dirty, overheat, mechanical damage, excessive temperature, storage in environment
whose temperature is lower than 0℃and water penetrating.
•Poor insulation resistance: uncleanness, high humidity, surface condensation as result of sharp
temperature variation, worn-out and aging of insulation material, etc.
