Thank you for your purchase the motors please read these instructions carefully before using and keep this manual in a safe place for future reference

Name of Model Declaration

General Description:

MS series motors an induction motor with copper stator winding and small squirrel cage. The protective class of motor housing is Ip44, cooling method is IC 0141
MS series motor should be operated as following conditions:
Ambient temperature not exceed 4°C
Height above sea level not more than 1000
Frequency: 50 HZ
Voltage and connection: HP and below, 220V connection with A ,380V
connection with Y, 5.5HP and over,380V connection with/,660v connection with Y.
Working method: SI(continues)
The value of temperature rise of stator winding(Resistance method): not over 105K.

Prepare work before mounting:

1. Please check whether the packing is damaged and wet or not before opening the packing box.
2. Please carefully clear off tbe dirt and antirust on the motor after opening th packing box.
3. Please check the data on the nameplate to see whether it is the same s demand;
4. Please cheek whether the motor is out of shape and damaged due ta long distance transportation, and also please remove the shaft of the otor to check whether the tight parts arc loosen and divorced or not.
5. Please measure the insulation resistance to see whether the value of the insulation is lower than 0.5 meg. If yes, the stator winding should be dried under the temperature not more than 120°C

Prepare work before mounting:

1. The motors are allowed to he driven by clutch, spur gear or pulley, 2.If the motor to be driven by V-belts, the shaft center line of the motor and the shaft center line of the loading parts should be of equal rank, the center line of belt  and the center of shaft should be vertical;
2. The center line of the motor shaft and the center of loading parts shaft should be coincided when the motor is driven with clutch.
3. The motors should be mounted on the place where have good ventilation and it is easily to be cooled.

Operating of the motors

1. The motors earth unit which located on the terminal box should be well connected to the ground. If necessary. You can also get the screw bolt as earth unit connected between the earth and the frame foot or flange.

2. There are 6 connectors on the terminal box, they are separately marked as follows:
   Phase sequence| A| B| C
   ---|---|---|---
   Head| U1| V1| W1
   Tail| U2| V2| W2

3. Please connect the motor to be or Y connection according to the connection method lisped on the nameplate.
   When the power phase ABC are corresponding with the binding post U1, V1 ,W1, you will notice that the rotation of the motor is clock wise rotation from the main shaft end. If you change the power source phase sequence the  rotation direction of the motor will be totally opposite.

4. ‘The motors are allowed to be started with full voltage or to be stated with step-down voltage( with reaction machine or Y– start).But please note, When it is stated with full voltage there will be about 5to 7 times staring current than  the rated current, when it is started with step–down voltage, the torque ls direct ration compare with the square of voltage. Please start the motor with step down voltage when the power source is not enough.
   Please start the motor with full voltage when the static loaded is on high side.

5. When the deviation of the frequency between the power source and the date marked on the nameplate is more than 1%, or the deviation of the voltage is more than 5%, the motor will not assure to continuously offer rated output.  For the continuous working motor. Please don’t make it over load.

6. The motor should not have the intermittent or unusual sound or vibration during the motor is on load or no load, the temperature of the bearing should not exceed 9 °C.

Maintenance and repair of the motors

1. The motor should be used and kept on the dry place, the surface of it should be kept clean, please don’t make the part for fan to be influenced by the dust.

2. During operating, please assure the motor is in good lubricating Usually, after the motor have being operated 508 hours or so, you should add more or exchange the lubricating to it(To the closed)bearing, no need to change the  lubricating, if motor is still in is its life.
   During the motor is on operating, if you found the bearing is over heat or the lubricating goes bad, please exchange the lubricating immediately, During exchange the lubricating, you should clear off the old lubricating, and also clean the bearing and bearing cover with gas, then put the ZL.–3 lithium case lubricating grease on the outside and inside of the bearing.
   For the 2pole motor, to put grease half of the inside and outside cavity of the bearing is enough, but for the 4pole, 6pole and 8pole motor, you should put the grease about 2/3 of the inside and outside cavities of the bearing.

3. When the bearing nearly end is life, the vibration and the noise of the motor’s running will be absolutely stronger than before, Checking the bearing, of you find radial lash has reached the below marked figure, please change the bearing.
   Bearing’ s internal dieter| 20-30| 35-50| 55-80| 85-120
   ---|---|---|---|---
   Limited frazzle lash| 0.1| 0,15| 0.2| 0.3

4. For taking-down the motor, to take out the rotor from the shaft end or the opposition both are permitted. If no need to take down the fan, it will be more convenient to take out the rotor from the fan end. When taking shaft from  the rotor the rotor, please try to Avoid the winding and insulation of the rotor being damaged.

5. During exchange the winding please take note for the former winding’s figuration, dimension, number of turns and gauge etc. If you lose these date, please contact with the manufacturer, If you change the former design on windings at will, it will make some or several performances of the motor worsen, even further, the motor could not be operated any more.
