wound rotor meaning in Hindi

Examples

1. Induction motors may be further divided into Squirrel Cage Induction Motors and Wound Rotor Induction Motors.
2. This reactor or filter reduces the voltage stack up that can occur on older high impedance motors such as wound rotor motors.
3. Transistorized inverters with variable-frequency drive can now be used for speed control, and wound rotor motors are becoming less common.
4. A DFIG configuration will require the generator to be a wound rotor; squirrel cage rotors cannot be used for such a configuration.
5. It is based on an induction generator with a multiphase wound rotor and a multiphase slip ring assembly with brushes for access to the rotor windings.
6. In wound rotor motors, rotor circuit connection through slip rings to external resistances allows change of speed-torque characteristics for acceleration control and speed control purposes.
7. What type of generator is suitable ( asynchronous ) and what type of rotor ( squirrel-cage rotor, wound rotor, salient pole rotor or cylindrical rotor )?
8. The rest of the regulator's construction follows that of a wound rotor induction motor with a slotted three-phase stator and a wound three-phase rotor.
9. Liquid rheostats were sometimes used in large ( thousands of kilowatts / horsepower ) wound rotor motor drives, to control the rotor circuit resistance and so the speed of the motor.
10. Compared to squirrel cage rotors, wound rotor motors are expensive and require maintenance of the slip rings and brushes, but they were the standard form for variable speed control before the advent of compact power electronic devices.
