What is the Difference between 415v 3 phase motor with a 230v 3 phase supply?

Answer 1

IF YOUR MOTOR HAS 6 LEADS (IN THE TERMINAL BOX) OR 9 OR 12 LEADS THERE IS NO PROBLEM. IF IT IS A BRAND NEW MOTOR THE WINDING CONNECTION DIAGRAM IS NORMALLY INCLUDED IN THE NAMEPLATE OR INSIDE THE TERMNAL BOX - T1,T2,T3,T4,T5,T6 OR U,V,W,X,Y,Z MARKINGS. DUAL VOLTAGE APPLICATION IS A NORMAL OPTION FOR MOTORS. IN THIS CASE CONNECT IT IN WYE (SOME CALLED IT STAR) CONNECTION BY CONNECTING OR COMBINING T4,T5,T6 AS COMMON OR NEUTRAL THEN APPLY 230V 3 PHASE POWER SUPPLY AND CHECK DESIRED ROTATION OR ELSE JUST INTERCHANGE ANY TWO SUPPLY LINE TO CORRECT ROTATION.

Answer

Judging from the values of voltage that you quote, you appear to be referring to the UK supply system. In that case, a three-phase supply has a line voltage of 415 V and a phase voltage of 240 V. So you can simply connect the machine's controller directly to the three line conductors. (These days, the nominal voltage for UK supply is now 400/230 V although, in practise, it is still 415/240 V).

Answer 2

This seems like a question from an electrical course, and is probably best answered by referring to your course materials.

It's your test question, not ours, and there won't always be someone else to ask for the answer.

Earn your diploma.

Answer 3

You can not run a three phase motor on single phase Source. You can use a VFD (variable frequency drive) or a rotary phase converter to supply your three phase motor from a single phase source. For large motors it can be expensive.

Answer 4

With the mention of 415 supply voltage it suggests that the supply frequency is 50 hertz. Without knowing what the frequency of the 230 volt three phase motor is, a solution to the problem can not be given.

Answer 5

no. it clearly needs a 415 volt 3 phase motor.

Answer 6

Check the motor name plate details or the data sheet of the motor.

Normally 230V AC 50 Hz, 3 phase motor can be connected in star with 415 V AC 50 Hz supply.
