A dc series motor with speed control can be connected on ac supply because dc machines are totally reversible.
Basically AC motors would not work on DC supply but there's however an exception for a Universal motor also known as a series motor. This is the only motor as far as I know that work on both AC and DC.
it burns thats it
why does the lamp bright when it is connected to the AC supply
It depends on the construction of the motor. If the field winding is connected in series with the armaturewinding, the motor is like a universal motor and will probably operate normally. If the field winding is connected in parallel with the armature, the motor will not run, but will draw current, make noise and get hot.
As the motor is a three phase machine,it must be AC supply
The direction of the motor is dependent on the way the stator coils are wound.
frequency of the power supply it is connected to. The speed of a single phase motor is directly related to the frequency of the alternating current (AC) power supply. As the frequency of the power supply changes, the speed of the motor will also change.
Ac motor have slip ring, to remove the slip ring,connected to the commutator its a dc motor.
motor will not rotate
the universel motor can runs at both ac and dc supply.
opposes changes in current
