What are the standard voltages of 3 phase induction motor being manufactured?
Wiki User
∙ 16y ago
The stator and rotor of a machine are not made from sold pieces of metal. They are constructed by clamping stacks of thin sheets of silicon steel, called 'laminations', together. Laminations are essential to minimise circulating currents due to voltages induced into the core/rotor when the machine is operating. These laminations are created by a stamping machine, which cuts the required shape from large sheets of thin metal.

∙ 14y agoThe voltage ratings of a 3 phase motor vary through out the world depending on what the local power distribution system uses. In North America there is 600 volts 480 volts. There are some 240 systems still in operation but this voltage is being phased out for the higher system voltages.

What did means by the stray losses in induction motors or transformer or generator?
Stray losses refer to secondary voltage to be inappropriately distributed to transformers, induction motors and generators. Stray losses essentially mean that there is leakage that causes a weakening of the voltage being delivered to the motor.
Why resistor needed to know the characteristics of diode?
The resister always being used to save components to damage by absorbing extra voltages, diode works on 0.7 volts n usually having 15 volts from the source so extra voltages drops across the resister and it works safely.

What is C99?
The ISO C standard that came into being in 1999.
How emf is induced in dc motor?
In brief,in a 3 phase SQIM,there are 3 windings per pole in the stator physically 120 degree apart,each of which is fed from per phase of a balanced 3 phase ac supply.As the magnetic field due to current in each winding varies with time as the current is alternating,the resultant field will be found to keep on changing its direction with time in a circular locus,magnitude being constant because of this setup which can be shown mathematically.Thus a rotating flux of constant mag links the rotor which induces an emf in the rotor,though initially both rotor & stator are static.Another AnswerA three-phase induction motor is, essentially, a transformer. The 'primary' windings being the stator's field windings, and the 'secondary' winding being the bars of the rotor. For this reason, induction motors are often termed 'rotary transformers'. So emfs are induced into the bars by 'transformer action'.Unlike a 'static' transformer, however, the secondary voltages and the frequencies of the voltages vary with the speed of the rotor.
Is a standard cooktop or an induction cooktop better?
An induction cooker uses induction heating for cooking. Unlike other forms of cooking, heat is generated directly in the pot or pan cooking vessel, as opposed to being generated in the stovetop by electrical coils or burning gas
Are high standard 22 pistols still being made?
Yes, although the current company known as High Standard is not the original High Standard Manufacturing Company, which folded in 1984. But it's the same pistols being manufactured currently, although there may be some cosmetic variances.
One application of induced magnetism?
Electromagnetic induction occurs when a conductor moves through a magnetic field. It produces a voltage in the conductor, and if the conductor is part of a complete circuit it creates a current. It's applications include electric motors which are used in many household products (washing machines, tumble dryers), and some forms of transport (electric cars and trains). Generators use electromagnetic induction. Almost all power is generated by a moving turbine attached to a generator. Either the turbine is moved by steam from burning a fuel to heat water, or is being moved by water or air (wind turbines and hydroelectric power plants). Transformers, used for transmission through power lines and power supplies, use electromagnetic induction. They are used to up-scale or down-scale voltage in alternating current (AC). They are used to send electricity through power lines at high voltages (above 111,000 volts) to lower lost energy. They are then used to down-scale the high voltages from power lines to lower voltages (240 to 110 volts) for transmission to households. More transformers are used in power supplies to down-scale this to lower voltages used by household electronics. Electromagnetic induction often incurs a lot of energy transferred into heat. Which can be used for welding or any kind of heating, known as induction welding or induction heating. Induction was one of the first methods of detecting touch on a surface, and was used for early graphics tablets. Induction is used in Electromagnetic forming, which uses high intensity pulsed magnetic fields to shape objects. Pickups use electromagnetic induction to convert vibrations from a stringed instrument and converts it into electrical current which can be amplified into a speaker or recording device. Pickups are used in electric guitars. Electromagnetic induction is also used in electric hobs on cookers. It uses induction heating to heat a pan without the need for fire.
What is the induction mean?
Leading or drawing; persuasive; tempting; -- usually followed by to., Tending to induce or cause., Leading to inferences; proceeding by, derived from, or using, induction; as, inductive reasoning., Operating by induction; as, an inductive electrical machine., Facilitating induction; susceptible of being acted upon by induction; as certain substances have a great inductive capacity.
What happens in an electrical generator?
To state it in the simplest terms, wires are caused to pass through magnetic fields. As a result, voltages are generated in the wires. That being said there are alternative ways of look at it. Look at Wikipedia.org's article on induction for the principle at the heart of it all. Refer to the related link in the Related Links section below.
Where are Tory Burch shoes manufactured?
the shoes used to be manufactured in LA and Brazil. Currently her products are being manufactured in China.
When being induced and waters are broken What is the next stage?

What is the difference between orientation and induction?
INDUCTION is a primary introductory course mostly designed by organizations for their new appointees to acclimatize themselves with the new office environment and organizational structure, whereas TRAINING is imparted to the employees with some experience in the organization to enhance their knowledge, skills to improve quality of service. There is not a huge difference between orientation and induction. Induction is the being accepted and orientation is being shown what to do once inducted.
Are Linytron televisions still being manufactured?

How can science contribute in technological development?
Science is technology. Whenever science leaps...a machine using that formula arises. When science discovered Induction technology, Induction cookers came into being.
What is the standard voltage and amperage in Toronto Canada?
The standard home voltage connection is single phase 120/240 volts. The amperage is what ever the service size requires. For new homes it is usually 200 amps. For business voltages it usually is three phase 120/208, amperage demand governed by equipment. For new industrial and commercial buildings the voltages are three phase 347/600 volts, amperage demand governed by equipment. For old industrial and commercial buildings the voltages are three phase 277/480 volts, amperage demand governed by equipment. The three phase 277/480 systems are being phased out for newer 347/600 systems.
