Adjusting the resistance allows control of the speed torque characteristic of the motor. If the full resistance is inserted into the secondary circuit when the motor is running the rotor current decreases and the motor speed decreases. Wound rotor motors can be started with low inrush current by inserting high resistance into the rotor circuit. Applications of squirrel cage induction rotor. Consider figure 1 in which a one loop wire for simplicity is placed inside a rotating magnetic field. Also notice that the resistor is external to the wire loop and its connection to the wire loop is through slip rings that are mounted on the shaft. Rotor is also cylindrical in shape and has slots to carry winding. Are connected to 3 slip rings. We will discuss the types of rotors used in 3 phase induction motors in the following section of types of three phase induction motors. Types of three phase induction motors three phase motors are classified mainly in two categories based on the rotor winding armature coil winding i e.

Notice that the single wire loop is connected to a resistor and together they form a closed loop. In wound rotor induction motor the rotor has a 3 phase winding similar to stator winding. Squirrel cage and slip ring wound rotor motor. Wound rotor motors can be started with low inrush current by inserting high resistance into the rotor circuit. If the full resistance is inserted into the secondary circuit when the motor is running the rotor current decreases and the motor speed decreases. Rotor of wound rotor induction motor. Adjusting the resistance allows control of the speed torque characteristic of the motor. Traditional squirrel cage induction motors can require anywhere from 400 to over 1000 percent of their full load current when starting. We will discuss the types of rotors used in 3 phase induction motors in the following section of types of three phase induction motors. Three phase wound rotor induction motor.

Types of three phase induction motors three phase motors are classified mainly in two categories based on the rotor winding armature coil winding i e. We will discuss the types of rotors used in 3 phase induction motors in the following section of types of three phase induction motors. In wound rotor induction motor the rotor has a 3 phase winding similar to stator winding. The below diagram shows a squirrel cage induction rotor having aluminum bars short circuit by aluminum end rings. As the motor accelerates. We use the. That was the basic structure of stator now let s talk about rotor. As there are no brushes and slip ring these motors requires less maintenance. Traditional squirrel cage induction motors can require anywhere from 400 to over 1000 percent of their full load current when starting. Notice that the single wire loop is connected to a resistor and together they form a closed loop.

In wound rotor induction motor the rotor has a 3 phase winding similar to stator winding.

Rotor is also cylindrical in shape and has slots to carry winding. Slip ring rotor or wound rotor or phase wound rotor. Wound rotor motors can be started with low inrush current by inserting high resistance into the rotor circuit. Its construction is very simple and rugged. As the motor accelerates. Traditional squirrel cage induction motors can require anywhere from 400 to over 1000 percent of their full load current when starting. In wound rotor induction motor the rotor has a 3 phase winding similar to stator winding. Also notice that the resistor is external to the wire loop and its connection to the wire loop is through slip rings that are mounted on the shaft. We use the.
