Induction motors are used extensively in heavy industry. For these loads, this often requires reclosing on the motor before it reaches zero speed. However, if the supply voltage is applied before the motor reaches zero speed, the motor can be damaged due to excessive current and torque transients.

A new steady-state model describes synchronous reactance over the whole operating region of the machine. The model takes into account main and cross-axis magnetic saturation. An analysis is presented of saturation as a function of the total air gap ampere-turns which shows that complicated relationships exist at leading power factors making such relationships unuseful. Two large turbogenerators of... View full abstract»
