If a DC series motor is operated at no load, it runs so fast that it destroy itself. The high forces, associated with high speeds, cause the rotor to fly apart, often wit ... Voir Plus
if we start Dc series motor without load then it shout more and may get damage itself ............ so in simply words we can say if applied load its get quit ......... ... Voir Plus
Series motor cannot be started without load because of high starting torque. Also at no load the current passing through the field is minimum and almost zero ,so the flux ... Voir Plus
As we know that, for DC Series motor equation of torque is given by Torque= k*flux*(I)^2 At no load I=0 which means torque=0 and torque i ... Voir Plus
First of all inorder to select guage for a GI duct there are SMACNA standards for guage selection. 0-450mm=24 guage (0.6mm) 451mm-900mm=22 guage (0.8mm) 901mm-1219mm=20 g ... Voir Plus
volume = Area * length of duct .It can be described in Sq.Mts or Kgs.
