II. Trial operation and ordinary operation 

1. Before powering 

All of your purchased motors from us passed severe tests at our factory however, they may have a 
possibility of being damaged during transportation or affected by long storage, and so carry out 
following checking, confirmation before starting of operation. 

 

(1) Precautions for working before trial operation 

1) Check that the shaft fixer and cover for the time of storage were removed. 
2) Check whether electric wiring was correctly carried out and terminal box cover was fitted. 
3) Check whether loose tightening bolts are found at individual part. 
4) Check whether the motor is well ventilated. 
5) Check whether rotating part contacts fixed part when the shaft is rotated manually. 
6) Measurement of insulation resistance of stator coil to earth. Disconnect the motor main 

circuit at the terminal block of the controller side and measure insulation resistance using 
500V Megger between motor terminal and earth. Although it is difficult to generally indicate 
the insulation resistance value, criterion is 1MΩ or over. 

7) Check whether earth terminals of individual part are completely connected. 

 

(2) Lubrication 

For the grease lubrication type motors, the bearing portion is filled with grease before 
shipment. However, if they are not used for more than 6 months after arrival at the site, the 
grease must be replenished soon after starting of operation. This work is not necessary in case 
of use of sealed-grease type bearing. 

 

(3) Others 

Check the status of direct connection and belt tension as well as tightening of bolts and nuts of 
the individual part. 

 

2. After powering 

 

(1) In the initial operation, the motor should be operated with no load independently at as low as 

possible speed in order to confirm no abnormality. After that, the motor should be connected 
with the counterpart machine. 

 

(2) After starting of operation, check the following points. 

1) Whether direction of rotation (standard direction of rotation is clockwise as seen from non-

load side) is correct. 

2) Whether abnormal sound is heard from the bearing part. 
3) Whether abnormal sound is heard from inside of the motor. 
4) Whether burning smell of insulator, etc. is sensed. 
5) Whether abnormal vibration is sensed. If the total amplitude exceeds 30μm, investigate the 

cause and take necessary measures. 

6) Whether supply voltage and phase current are balanced. 
7) Whether starting time is abnormally long. 

 

Checking the above points, proceed independent operation, no-load operation, full-load operation 
sequentially and if all of them are normal, start full scale operation.
