(TRUE OR FALSE) - Shunt motor should not be started on no-load. - Field copper loss is likely to have highest proportion at rated load of the DC generator. - In a DC generator, the iron losses mainly take place in the commutator
(TRUE OR FALSE)
- Shunt motor should not be started on no-load.
- Field copper loss is likely to have highest proportion at rated load of
the DC generator.
- In a DC generator, the iron losses mainly take place in the commutator.
- Energy conversion of DC generator is based on the principle of
production of dynamically terminal voltage.
- Increasing the speed of DC motor, the back emf will decrease but the
line current falls.
- The current drawn by the armature of DC motor is directly proportional
to torque.
- Lenz’s law rule is used to determine the direction of rotation of dc
machines.
- Compound dc motor at no-load it regulates highest speed.
- The direction of this force is perpendicular to both the wire and the
magnetic field in DC motor.
- The direction of DC motor induced emf is such that the same of the
armature current.
