turn off supply - Opis:
- The dynamic states of the induction motor and a synchronous motor, which works in a steady state, and then the supplying voltage has been turned off and then turned on are presented in the article. During moment ary power failure, the excitation flux in induction motor does not disappear. The motor rotates and in the armature winding the rotational voltage is induced. The excitation flux changes its speed in a stepwise way from the synchronous to the rotor’s speed, it means the flux "sticks" to a rotor and then with a relatively long time windings electromagnetic constant of the rotor fades to zero. When the supplying voltage is turned on, in the most unfavorable circumstances, the current Iu can reach the value 18IN, and the torque can reach the value 10TN. The exciting current in the synchronous motor, due to the large electromagnetic time constant of the rotor’swinding (opened stator windings), causes an increase of the magnetic flux and increase of the induced voltage of rotation in the stator’s winding. When the most unfavorable circumstances appear, the current Iu can reach the value 25IN, and the torque can reach the value 18TN.
