The conversation between human and AI assistant.
How one can make torque inversely proportional to the speed or supply frequency by keeping supply voltage constant in induction motor?
How does the flux control method work?
The flux control method works by adjusting the rotor resistance to control the amount of flux in the motor. This is done by adding or removing rotor resistance through external controllers. When the rotor resistance is increased, the amount of flux in the motor decreases, which in turn reduces the speed and increases the torque. Conversely, when the rotor resistance is decreased, the amount of flux in the motor increases, which in turn increases the speed and decreases the torque.
