The starting intensÜy is consumed when 1l10tor 1S at sta tic rotor. It is a characteri stic of lhe motor a nd its value i s measured duri ng the motor tests.

The  norninaJ inten sity 1S a bsorbed  wben the motor i s worhng at nominal  power and is connected Ito a nominaJ

voltage. The following  equ ation gives  its val ue:

POWER  FACTOR

The power factor  (Cos<p) is a quali ty electric  factor of the motor. The rugher it is、l ess intensity wW be absorbecl

to gi ve the same power. Its value indicates  the "qu ality" of  lhe motor related to its cons Ll mpti on. fts m ax imu ll1

VOLTAGE DROl-"

For three-phase alternating clment:

.6U= Vo1t age c1rop in Volts.

1= AmpeI'age Ìli Amps. L= Length  in m.

z= Impecl ance ()f the conductors in 111m.

Lenght lo be consi.derecl for the voltage drop caJ culation (System  length= L):

- Power supply in ()ne extreme= Ul                      - Power suppl y in rhe cen甘e= L/2

- Power  supply in both extremes= Ll4                   - Power supp]y at 1/6 from cach extrel11e= Ll6

The value of L is redLl cecl when the width of the mobi l e machine is con sidered. The system  length  jncludes the feedjng  track length + feeding cable lenεth.
