Difference between 12volt armature and 24 volt armature?
24 volt armature is accept balancing cut
What is the difference between armature reaction and armature reactance?
armature reactant means loss in armature associated with inductive properties of the coil, while armature reaction include losses due to magnetizing component of current flowing through armature.
What are the differences between brakes and rotors?
There is no difference between brakes and rotors because the rotor is just one of the many parts that make up a brake. The function of a brake rotor is to stop the wheels from spinning. The rotor is what the brake clamps hold on to stop the car.
What is armature reaction in dc machines?
The armature reaction is the interaction between armature flux and field flux when current is introduced to a dc motor. It results in a cross-magnetizing effect and a demagnetizing effect.
What is the difference between a synchro and resolver?
1.synchro is a electromecnical device of three stator and one rotor,whearas resolver is a device of two rotor and two stator 2. In synchro stator is 120 deg aparted,,,,,,,,in resolver 90 deg aparted 3.synchro output in taken from stator,,in resolver output can be taken from either synchro or rotor
Difference between 12volt armature and 24 volt armature?
24 volt armature is accept balancing cut
What is armature in DC motor?
The armature has the stationary (not physically moving) magnetic field, which attracts the magnetic field in the rotor. Since DC does not alternate, a split ring is used to alternate the current (and resulting magnetic field), so that the rotor will spin.
What does a armature or rotor do?
The Armature(or rotor) is a electromagnet inside a motor and alters the magnetic field inside the motor when it rotates. In DC motors it is connected to a Commutator. In AC induction motors the armature isn't connected to a power source.
What is the difference between armature reaction and armature reactance?
armature reactant means loss in armature associated with inductive properties of the coil, while armature reaction include losses due to magnetizing component of current flowing through armature.
Why the induction motor does not have armature reaction?
Because the armature (or rotor) has no external connection. The currents that produce torque from the rotor are induced by the magnetic field in the machine, so there is no commutator, no brushes and no armature reaction.
Does armature rotates?
Typically the armature windings are in the stator of a generator, which does not rotate. Typically the field windings are on the rotor, which rotates.
What is Comparison of armature controlled and field controlled DC servo motor?
Difference between field controlled and armature controlled is that field control is open loop and armature current is closed loop.
Why armature winding resistance is less than field winding resistance?
An 'armature winding' is the rotor winding, and the 'field winding' is the stator winding.
What is armature current?
Armature current is the current flowing in a motor's armature. The "armature" is another name for the coil (or coils) of wire which are on the motor's "rotor", which is the part that rotates inside its stator. (The "stator" is the fixed, non-rotating part of the motor.)
What three things are required to produce EMF in an alternator?
armature, stator, rotor
What is armature in motors?
The armature has the stationary (not physically moving) magnetic field, which attracts the magnetic field in the rotor. Since DC does not alternate, a split ring is used to alternate the current (and resulting magnetic field), so that the rotor will spin.
What is mean by rotor in machines?
a ROTOR is basically any part of a machine that rotates. eg the armature in a motor a STATOR is the part of a machine that is stationary. ie the ROTOR revolves within the STATOR
