What is a stator made from?
The stator frame consists of laminations of silicon steel, usually with a thickness of about 0.5 millimetre. The stator coils are normally made of copper; round conductors of many turns per coil are used for small motors, and rectangular bars of fewer turns are employed for larger machines.
Why is a stator core made of laminated steel?
Reduces Eddy Current How much loss depends on several factors including frequency of EMF and density of magnetic flux. Stator laminations reduce eddy current by insulating the core. Thin silicon steel plates are stacked on top of one another around the center, preventing eddy current flow.
Which rotor construction is used in diesel engines or hydel generators?
The salient pole type motor is generally used for low-speed operations of around 100 to 400 rpm, and they are used in power stations with hydraulic turbines or diesel engines.
What are the main parts of synchronous generator?
In general, synchronous generator consists of two parts rotor and stator. The rotor part consists of field poles and stator part consists of armature conductors. The rotation of field poles in the presence of armature conductors induces an alternating voltage which results in electrical power generation.
What will a bad stator do?
Without a stator, your motorcycle will not get any spark at all as your battery is not capable of supplying the appropriate power levels to generate a spark. As a result, if your stator is going bad your motorcycle will run very poorly. Eventually, your stator can prevent your motorcycle from starting at all.
Which kind of rotor is most suitable for turbo alternator which runs at high speed?
177. What kind of rotor is most suitable for turbo-alternators which are designed to run at high speed? 178. The power developed in the alternator having salient type rotor is less than of having non-salient pole.
Why is the stator frame made up of cast iron?
It must be strong and accurately machined to that the stator is concentric with the rotor. It can be made of cast aluminum, cast iron or fabricated steel plates. The material is selected based on cost, heat transfer characteristics and manufacturing capability considering the size of the machine.
Why is a generator stator core made of laminated steel?
The stator core is made up of thousands, tens of thousands, or hundreds of thousands of individual steel laminations.
Which is used in the stator and the rotor?
The stator is used to generate a magnetic field within the air gap of the electrical machine. 2). What is the difference between the stator and the rotor? In the motor or generator, the stator is the stationary part whereas the motor is the rotating part. 3). Which supply is used in the stator as well as the rotor?
How is a magnetic field generated in a stator?
The main function of this is to generate a magnetic field within the air gap of the electric machine. Once the power supply is fed within the coils, then a magnetic field can be generated to supply throughout the air gap & get connected to the conductor of the rotor, inducing voltage within the rotor of the machine.
