Similar to DC permanent magnet motor (which I'm assuming you understand); except the stator is not a permanent magnet but an electromagnet. There are 2 separate coils on the stator, which are connected in series with the brushes and armature:
supply ----- stator segment --- brush - armature - brush --- stator segment ----- return
Since the stator coil segments are wired in series with the armature, reversing the supply will *not* change the direction of rotation; as both magnetic fields will reverse together. (But a reversing switch affecting only the armature *will* reverse the rotation.) And since the motor will always turn in the same direction independent of the supply polarity, this means it will work equally well from DC or AC; and the supply frequency will not affect the rotation speed.

Explain the principle of operation of a 3 phase induction motor with the help of relevant vector diagrams on no load and load?
The best way to do this is to find the diagrams. Do a quick image search to find the information that you need.
Is universal motor type of inductin motor?
No,look at the connection diagram for Universal motor. The Field and the armature windings are connected in series. But, in induction motor, the rotor end terminals are sorted by a kind of rings.That is rotor is apart from the supply.
How do you identify a motor and a generator without operation?
a motor drives something a generator is driven by something
What is working principle?
A working principle is a regulation or rule that is used so that work can be done. This is a general phrase that can be used in any circumstance from the working principle of a motor, to the working principle of a solar cells.
Why is it said that generator is a motor working in reverse?
because working principle of both the things are same.The motor converts electrical energy in to mechanical via magnetic induction and generator do the exact opposite of this.And yes,you should use 'electricity generator' not only 'generator'.
Operation principle of hysteresis motor?
Give a brief idea of principle of hysteresis motor,application.
Which part of a universal motor does not move?
The stator of a universal motor does not move. It is the stationary part of the motor that contains the windings and produces the magnetic field needed for operation.
Can AC motor work on DC?
use a inverter to change dc to ac or couple it to a ac motor making it a motor generator. Comment: AC motors cannot run on DC since their principle of operation based on induction. There's an exception,however, and thats for Universal Series motor which can run on either AC or DC.
Principle and operation?
principle refers to the basic objective of something. Operation refers to how it operates.
Which type of motor is used in wet grinders?
A universal motor is used to operate a food mixer.
Explain about construction of universal motor?
construction of universal motor
What is the working principle of motor?
motor works on the principle of mutual induction.
What device is used on a power tool's universal motor to provide a burnout-proof motor?
A thermal overload protection device is typically used on a power tool's universal motor to prevent overheating and avoid burnout. This device monitors the motor's temperature and shuts off power if it reaches a critical level, preventing damage and ensuring safe operation.
What is sometimes called a rule of nature?
A rule of nature is a consistent pattern or principle that governs the behavior or operation of the natural world. It is a fundamental, universal law that describes how things work in nature.
What is the principle of universal testing machine?
Utm works on force and elongation/deformation principle.
What kind of motor is used in mixie?
universal motor
Which motor used in ac and dc?
universal motor
