Abstract :
Many manufacturers of polyphase squirrelcage induction motors in the integral horsepower sizes have now added to their other products, a modified form of squirrelcage motor in which the starting current is reduced below that of the standard squirrelcage motor. The reduction in starting current is sufficient to warrant the power companies throughout this country to permit the starting of these motors directly across the line without the use of a starting compensator. This type of motor is now sold under a variety of trade names, such as line-start motors, auto-start motors, double-deck motors, double squirrelcage motors, high-reactance motors, etc.
