It depends on whether the field winding of the dc motor is connected in series or in shunt with the armature winding.If it is connected in series,the motor will rotate since the torque,which varies as the product of the armature and field current is always positive.Thus,a positive average torque causes the motor to rotate,however the pulsating nature may cause the commutator segments and brushes to wear out.
Thus only small sized dc motors may be used with ac supply.
What else can I help you with?
What type of motor is used in ac servometer?
ac motor
Is schrage motor ac?
As the motor is a three phase machine,it must be AC supply
What the main different between shunt motor and induction motor and AC motors?
induction motor is AC motor also synchronic motors are AC motors but second one has not slip but first one has slip . shut motor is DC motor
What is the different between ac dc motors?
DC Motor works on DC source and AC motor works on AC source
Is the electric motor in a Ford Fusion hybrid AC or Dc?
It is an AC powered vehicle. It has an 88KW Magnet AC Synchronous Motor
What type of ac motor will operate at a constant speed from no load to full load?
The Synchronous motors will operate at a constant speed from noload to fullload. Even it is classified as an AC motor, we have to fed the motor both AC and DC supplies. That we have to supply DC to the Field (Normally Rotor) and AC to the Armature (Normally Stator).
What will happen if you will give ac supply to dc shunt motor?
it will not work.
Which is more effecient an ac motor or a dc motor?
ac
What type of motor is used in ac servometer?
ac motor
How does an ac drive variable speed drive operate to control speed?
Answer #1 It varies the frequency fed to a synchronous AC motor. As the frequency changes, so does the motor speed. Answer #2 The formula for calculating speed is: (120 X motor supply frequency) / number of poles 120 is a fixed number, so is the number of poles for a given motor, hence the only variable is the motor supply frequency. AC drives vary the motor supply frequency in turn achieving speed control.

How do you calculate 3ph AC motor power?
How do you calculate 3ph AC motor power?
How do you change an ac motor to a DC motor?
Ac motor have slip ring, to remove the slip ring,connected to the commutator its a dc motor.
What the main different between shunt motor and induction motor and AC motors?
induction motor is AC motor also synchronic motors are AC motors but second one has not slip but first one has slip . shut motor is DC motor
What is AC motor and DC motor?
AC stands for alternating current, and DC is direct current. A motor is a device that uses electrical energy to spin. An AC motor uses AC voltage, and a DC motor uses DC voltage. http://ezinearticles.com/?The-Difference-Between-AC-and-DC-Electric-Motors&id=193767
