Noise
Sound or vibrations checks postulate to move done when the electrical motor is operating, audio or vibrations checks tin move done manually, yesteryear listening to abnormal sounds.

A to a greater extent than accurate show tin every bit good move done using a stethoscope, to create upward one's take away heed the status of the motor bearing, This banking concern gibe tin move done Weekly.


Insulation Resistance
Insulation Test of electrical motor is divided into two, namely:
  • Insulation resistance of Power cable.
  • Insulation Winding of Motor.
This banking concern gibe is done yesteryear measuring the value of insulation resistance to create upward one's take away heed the character of insulation as well as leakage current.

This banking concern gibe is carried out when the electrical motor is non operated (Stop), as well as brand sure the ability source has been cutting off.

The inspection is carried out using an Insulation tester or Megger (Mega ohm Meter), as well as the insulation resistance value should move higher upward 5 Mega-ohm., This Check Done Annually


Termination
Checks are carried out yesteryear checking the tension of the cable final bolts, both inwards the electrical motor final as well as the cable final on the motor command panel (MCC).

Make sure the status of the cable fastening bolts is tight, as well as installed properly, Make sure in that location are no cable as well as bolt scones that are loose, dirty, moldy.

This banking concern gibe is done when the electrical motor is non operating, as well as the ability source is cutting off, This Check Done in 1 trial inwards 6 Months.


Electric motor panel
Electric motor panel checks or commonly called the MCC (Motor Control Center), carried out when the electrical motor does non operate as well as the ability source is cutting off yesteryear disconnecting the ability source from the top dog MCCB of the electrical motor.

Check the status of each connectedness termination, cable necktie bolts, MCCB, Magnetic contactor, overcurrent security such every bit Thermal overload relay, as well as diverse instruments flora on the panel of the electrical motor.

Ensure that each connection, the fixing bolt is properly installed, in that location are no bolts that are rusty, moldy, seat out as well as other abnormal conditions, Also brand sure the status of the MCC is build clean both exterior as well as inside, This Check Done Monthly.


Current Load-Ampere
Checking the amperage or electrical flow of an electrical motor spell operating, Checking is done yesteryear reading the criterion results on the panel ampere meter, as well as compared amongst the results of measurements amongst Clamp meter, as well as Make sure the criterion results are accurate as well as appropriate.

Make sure the amperage of the electrical motor does non laissez passer on 80% of the nominal electrical flow of the motor, This Check Done Weekly.


Bearing lubrication
Lubrication of electrical motor bearings must move carried out on a scheduled as well as regular basis, as well as brand sure the sum of lubrication is adjusted to the size of the electrical motor bearing.

Lubrication catamenia is carried out inwards accordance amongst the specifications of the bearing as well as electrical motor, for to a greater extent than details tin move seen inwards the article most the schedule of lubrication of electrical motor bearings


Oil
For electrical motors installed amongst a Gearbox (Gearmotor), of course, utilization Oil every bit a gearmotor lubricant.

Check the stone oil marker height, ordinarily the stone oil marker inwards the pump position, tin move seen inwards the sight glass, or other stone oil marker indicator, as well as Check the status of the gearmotor, brand sure in that location is no stone oil leak.

Perform regular stone oil changes, tin move done amongst a catamenia of every 5000 hours of operation.

Oil inspection as well as replacement is carried out inwards the trial the gearmotor is non operating, Check the status of the stone oil every 3 months.


Cooler
Each electrical motor is usually equipped amongst a cooler, as well as usually in that location is a fan that rotates inwards the electrical motor that functions every bit a cooler.

Check the status of the fan inwards proficient status as well as intact, in that location is no harm or broken fan grille, Check every bit good the status of the holes inwards the fan encompass create non clog, so that the current of air tin blow maximally when the electrical motor is operated.

Check the fan status as well as encompass when the electrical motor is non operating.

Next to ascertain whether the gusts of current of air from the fan are functioning properly, an inspection is carried out when the electrical motor is operating (Running), This Check Done in 1 trial inwards 3 months.
