So for a squirrel cage induction motor, these starters can be either one of the following: 1. Direct On-Line starter (DOL) 2. Primary or stator resistance starter 3. Auto-transformer starter 4. Star-Delta starter For slip ring … See more On giving a three-phase AC supply to an induction motor, a rotating magnetic field gets produced. This field links with the rotor conductors and creates torque for the rotor. In this way, … See more It is the most economical method to start low-rated induction motors (i.e., up to 1.5kW). This starter applies full voltage to the induction motor. Hence the rated full load current flows through the motor windings. Now, isn’t it … See more In all the induction motor starting methods, the aim is to reduce the starting voltage and hence, the starting current. In this method, an Auto-transformerdoes this job. The auto … See more This method uses resistors to create a voltage drop and hence reduce the starting current to the motor. Each stator lead consists of a variable resistor in series with it. So, during the … See more css old terminal

"WebReduced-voltage starting of Induction Motor. In some cases, especially for larger three-phase induction motors, it is necessary to start the motor at less than rated voltage to limit the current to (and the heating of) the motor. As we see in equation 1, reducing the voltage reduces the shaft torque by the square of the voltage reduction. " - Starting methods of induction motor
