Ok..electric motor manufacture design their product can suit with several value of power supply around the world.It made the motor can used at any countries without worried about their power supply value.
The value of voltage for all country’s around the world have variant such as 200 VAC,220 VAC,415 VAC or 440 VAC for 3 phase.That why some motor manufacture design their motor can operated with 2 types of voltage.So it available for use to any country around the world.
How to determine motor terminal connection for suitable voltage?
This part is very important to ensure our electric motor installation is done perfectly and running properly.If we wrong setting for voltage value connection for induction motor,it can cause serious damage.
But dont worry,this time i explain detail how to determine a motor terminal connection for suitable with our power supply.The key is motor nameplate.We can found the motor connection and their suitable voltage value.For more detail,please refer a picture below :-
From this motor nameplate,we can see it have 2 connection and 2 voltage value.If our power supply voltage is 415 VAC for 3 phase,we need to setting the motor terminal in STAR connection.
It mean terminal cooper plate W2,U2 and V2 connect in one line.Here i attached picture about motor terminal in STAR position.
STAR CONNECTION TERMINAL MOTOR
If our power supply is 200 VAC 3 phase,we need to connected the cooper bar terminal in DELTA position.It mean, a connection are U1 with W2,V1 with U2 and W1 with U2.It just need to follow the diagram shown in motor nameplate.
DELTA CONNECTION TERMINAL MOTOR
If you want connect the induction motor with star delta starter,what you must to do is take out all cooper bar from motor terminal.It mean we not use a cooper bar.Because the star delta starter use a 6 cables for run the motor.
I hope from this post it can help all of u how to connect or perform termination job for induction motor.It is very important to ensure our motor running in good condition and avoid any damage.That why the nameplate of motor is very important…
