how to adjust and install the star delta time at any machine especially in polar cutting machine

At the very beginning we can do this process without the load outside to set the timer to the timer relay recorded on the stop watch In star Delta usually we consider that the load and motor torque are equal when the motor reaches 75-85% of the speed. At this time you stop the star connection to go with the delta connection, the time is around 30 to 50 milliseconds, to avoid short-circuits if we have big flywheel and high motor amphere load we should do the star delta time adjustments on no load conditions by giving simply 24 volts or Ac 220 according to the timer specific voltage and it's will switch or change contact between normally close to normaly open #technology #diy #machine #electronic #music #equipment #electric #beats #automobile #explore
