What is the main material in a motor armature?
Instead of a single piece of metal, the armature is made up of laminated thin metal plates. The thickness of the laminations is determined by the supply frequency. They are approximately 0.5mm thick. For the armature core, silicon steel laminates are used to reduce eddy currents and hysteresis losses.
Why armature core is laminated in dc machine?
to reduce the eddy current loss in the machine
What is the physical specifications of armature?
The physical specifications of an armature can vary widely depending on its application, but generally, it consists of a core made of laminated iron or steel to reduce eddy current losses. The armature typically includes windings of insulated copper or aluminum wire wound around the core. Dimensions such as diameter, length, and number of turns are tailored to optimize performance for specific motors or generators. Additionally, the armature may include features like commutators or slip rings, depending on the type of machine.
Can laminated glass be tempered?
Tempered glass can be laminated, but laminated glass cannot be tempered.
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.
Ac relay and DC relay?
what is the meaning of ac relay and dc relay EDIT: a DC relay is simply a coil and core that pulls on an armature. An AC relay usually needs a shaded-pole core (couple of copper loops) to prevent the armature from vibrating at 60 cycles or so. The core, also, is laminated steel like a transformer; so is the armature to help contain the magnetic field. You should not substitute a DC rated relay for an AC , but the reverse should be ok, if voltage and current ratings are the same.
Why dc shunt generator does not have armature resistance?
It does have armature resistance.
What is LVL?
Laminated veneer lumber (LVL) is a material made of thick veneers laminated along the grain direction, hot pressed and glued, and then sawed. Compared with solid wood, LVL has the advantages of uniform structure, high strength and good dimensional stability, which can meet the application requirements of wood structure building, bridge, furniture and transportation. Main species: Masson pine laminated veneer, eucalyptus laminated veneer, Yunnan pine laminated veneer, Larch laminated veneer, poplar laminated veneer, bamboo bundle laminated veneer, bamboo and wood composite laminated veneer.
Difference between 12volt armature and 24 volt armature?
The main difference between a 12-volt armature and a 24-volt armature is the voltage rating at which they operate. A 12-volt armature is designed to run on a 12-volt electrical system, while a 24-volt armature is designed for a 24-volt electrical system. This difference determines the power and speed capabilities of the armature when used in electrical devices.
What are the effect of armature reaction in DC machine and how the armature reaction is minimise?
Armature reaction is the interaction between the magnetic flux produced by armature current and that of the main magnetic field in an electric motor or generator.
What is armature reactions in a synchronous machine?
Armature reaction is the effect of armature flux on the flux generated by the fied windings.Cross magnetisation and Demagnetising are its consequences.
What is the function of armature core in dc generator?
this is wer the armature conductors ar being mounted,therefor it helps the flexibility of armature conductors.
