How many types of winding are used in AC and DC motors?
IN DC MOTORThere are 2 types of windings:1. Field windingOn poles core which are on stator body.These are always concentrated type.2. Armature windingOn rotor on motor may be simplex or multiplex and lap or wave connected.IN AC (Synchronous ) MOTOR3-phase star or delta connected on stator (armature ) suppliedby 3 phase may be concentrated or distributed (usually preferred) .Rotor (field ) has concentrared in salient pole type nd distributed in cylindrical type supplied by DC supply.IN AC ( Induction ) MOTOR3-phase (star or delta connected) distributed winding on stator and wound rotor .In squirrel cage rotor short circuted copper bars are used.
What type of motor has a stator?
An electric motor has a stator and a rotor. The stator does not move. The rotor rotates inside the stator.
What are the parts of a dynamo?
Electric motor, the alternating-current alternator, and the rotary converter. A basic dynamo consists of a stator wound with copper coils and a magnetic armature. As the magnetic armature spins it induces a current in the copper coils.
How energy is transferred from stator to rotor?
when current is passing through the stator windings of motor magnetic field is develop ,due to it emf is produced inside the stator windings,that emf is further cuts the emf across stator due to which current flowing inside the rotor.
What does stator mean in Spanish?
The Spanish word for "stator" (motor part) is estator. But the word is also used for an "estate" of land.
What is a permanent magnet synchronous motor?
combination of sinusoidally wound stator and a permanent magnet for rotor design is the basis of PMSM.
Why is the rotation of a fan only in one direction although it is connected to an AC supply?
The direction of the motor is dependent on the way the stator coils are wound.

What type of motor has a stator?
An electric motor has a stator and a rotor. The stator does not move. The rotor rotates inside the stator.
Difference between squirrel cage and wound rotor induction motor?
Both have 3 a phase stator winding, the squirrel cage has a rotor with bars arranged around it's periphery, these bars are joined at both ends by a continuous ring. This forms a closed circuit of low resistance which is fixed. The wound rotor (slip ring motor) is similar in construction but the bars are replaced by copper windings, similar to those in the stator. They are star connected and the three ends are brought out to slip rings which allow an electrical connection to be made to the outside world. When no connection is made between these ends and the stator is energised, little current flows in the stator which does not turn, but when some resistance is inserted, current flows in the stator windings and the rotor rotates. As the rotor gains speed the resistance is taken out of circuit and the slip rings shorted together. The motor runs as a cage induction motor.
What is the meaning of open end winding induction motor?
Normally the machine is supplied from one side of the stator winding only and the other side is isolated connected in star or delta. Open-end winding means the neutral point of the machine is opened and now the supply is possible from both side of the stator winding of the machine.
Cr 125 stator ohms?
Looking for coil ohms and stator ohms. And possibly the voltage comming out of the stator .
How many stator poles are used for battery charging when using the 3A stator system?
On a 1.25 A charging Stator it only has 2 poles. Now on a 3A charging Stator it has 4 poles for the charging. And both have 6 poles for Lighting Stator. So always remember that.
How electrical genrator work?
The stator and the armature are both wound. An excitation current is applied to the field(stator) windings from a DC source like a battery in order to produce a magnetic field. The armature is connected to a turbine or diesel engine via a shaft. As the armature turns, it's windings cut the magnetic flux of the field windings inducing an emf in the armature windings.
Working principle of ac motors?
Michael Faradeys laws of electromagnetic induction:When a current is passed through stator winding, an alternating flux created on the stator winding which in turn cuts a rotor winding(wire wound motor)/short circuited copper bar(squirrel cage motor), then a current flows through it and as above one motors works.
How to Wind the stator of an AC machine?
How ti wind the stator of an ac machine
What are the parts of a dynamo?
Electric motor, the alternating-current alternator, and the rotary converter. A basic dynamo consists of a stator wound with copper coils and a magnetic armature. As the magnetic armature spins it induces a current in the copper coils.
