Hello All,

I dont know this is a right place or not for such query but as i m working on a sinamic project this contain

1 Basic Line Module = 400 kw
2 Single Motor Module=60 amp,85amp and 132 amp for 1PH7 - motors 22kw, 28kw and 50kw

i want to know how should i calculate the cable crossection in SQMM for the cables between drive and motor.

Is there any formula or chart or link which can help me

i gone through the catlouges and technical detaills for sinamics but i found there the maximum crosssection only


regards
simatic manager

Dear ,

Information provided by you gives me following data.

Assuming operating voltage 400v. I may suggest following Cable Sizes(PCP)

Motor rating         Cable size

22Kw                      6sq.mm

28Kw                      10 sq.mm

50 kw                       35 sq.mm

Hello SM,

Obtain a copy of the D21.1 Catalog and in the Motion Connect section power cables are described.
In the 2006 edition of D21.1 see page 5/5.  Generally the column marked "C" will be suitable.

mm^2 - Amps
16        66

25        84

35        104

50        123

70 – –  155

95 – –  192

120 – –221

150 – –234

185 – –267

Hope this helps...
