3 phase motor cable size

[Hereforhelp]

Hi all,



I’ve been asked to run a cable for a 3 phase DC motor. Not having much experience with motors would you work out cable sizing the same?



In the picture attached are the details I have received.



Any help would be great

As far as I know, there is no such thing as a 3 phase dc motor.
from the nameplate, i would guess that it is a servomotor.
there are special types of cables used to connect them to the servo drive.

Did they ask you to paint it with tartan paint too?

New member, be gentle.
anyway, it’s stripes for 3 phase.
Red, yellow, blue.
or brown, black, grey.

3v phase DC Motor?????????????

Can someone tell why a DC motor would have a frequency of 50Hz on the rating plate which clearly shows in the OP's picture

I assume that is a very large motor with a nominal weight of just under 5.6 Tonnes

I suspect either soneone is winding the OP up, or he is winding us up.

Until he comes back we won't know though.

Sorry typo I meant AC. It’s for a waste compactor.

4mm2 cable method C , min depending on the length of the circuit. Don't forget volt drop & startup current for choice of mcb. Please do your own check calculation to clarify the above.

It's not - it's got a frequency rating (50Hz) on the spec plate.

Read the thread, it's an AC motor, the D was a typo.
