Quizz Electro

• Braking

• Motoring

• Generating

Region where slip is greater than 1

• Motoring

• Braking

• Generting

Which of them is not a method of dynamic braking.

• AC dynamic braking

• DC dynamic braking

• Self-dynamic braking

• Plugging voltage braking

Is the speed of rotation of the air-gap field directly

proportional to the supply frequency?

• True

• False

The machine can only work as generator when it is connected to

• Supply

• Diode Bridge

• Stator

Which is the slip in Point c

• 1

• 0

• >1

• <0

The direct current flow through the stator produces a stationary magnetic field, and the motion of the rotor in this field produces induces voltage in the stationary windings. The machine therefore works as

• Motor

• Generator
