An asynchronous alternating-current machine, such as an induction motor or induction generator, in which the windings of two electric circuits rotate with respect to each other and power is transferred from one circuit to the other by electromagnetic induction.

Why direction is clock wise of 3 phase induction machine?
It depends which side of the motor you are looking at!
Why is the frequency of a synchronous generator locked into its rate of shaft rotation?
By definition a synchronous generator must be synchronous. If it is not "locked in" it is not a synchronous generator, but an induction machine.
Why is the number of poles of stator and rotor same in induction machine?
The number of poles on stator and rotor is always the same. If they are not equal?æno torque will be produced, thus, the machine will not function.?æ
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.
Describe whether the comb is charged by conduction or induction?
induction
Can you plug a 230V 50Hz welding machine into 220V 60Hz outlets?
FIRST THING I WANT TO KNOW THAT WHETHER YOU ARE TALKING ABOUT INDUCTION MACHINE OR SYNCHRONOUS MACHINE? IN INDUCTION MACHINE, RATIO OF VOLTAGE TO FREQUENCY MUST BE SAME FOR CONSTANT TORQUE. IN THESE CASE AS YOU CAN SEE, V/f RATIO IS NOT CONSTANT THEN INDUCTION MOTOR WOULD NOT RUN.
Are the friction losses of the machine linear in induction motor electrical machines?
yes
What has the author Jussi Huppunen written?
Jussi Huppunen has written: 'High-speed solid-rotor induction machine' -- subject(s): Electric motors, Induction, Induction Electric motors, Mathematical models
Why the no of poles are less in induction machine compared to synchronous machine?
The number of poles determines the speed a machine has to turn (RPMs). The more poles, the slower the machine can turn. I don't believe your statement is true. I've seen synchronous generators, for example, that turn at 1200 RPMS, and induction motors that turn at ~1800RPMs.
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 AC motor is used in an escalator?
we can either use dc series motor or induction machine ,but dc supply is not easily available so we use induction motor ,
What is induction heating?
Induction heating is the process of heating an electrically conducting object (usually a metal) by electromagnetic induction, where eddy currents are generated within the metal and resistance leads to Joule heating of the metal.induction heater including high frequency induction heating machine and middle frequencey heating machine. Induction heating applications for an induction furnace include induction welding, induction brazing, induction hardening, induction melting, quenching, forging, soldening, induction annealing and other forms of heat treatment. Induction heating is often used to heat graphite crucibles (containing other materials) and is used extensively in the semiconductor industry for the heating of silicon and other semiconductors. Induction heating can produce high power densities which allow short interaction times to reach the required temperature. That translates into lots of energy transferred into a material right now, with a very rapid rise in temperature.
Why direction is clock wise of 3 phase induction machine?
It depends which side of the motor you are looking at!
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 happens if the rotor in an induction machine is replaced with an iron cylinder?
Nothing. The motor won't run because you would no longer have the counter-acting magnetic field from the induction windings in the rotor.
What is the meaning of inductive?
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.
Can you make a generator out of a motor if not why not?
u can make it run but not the induction ones. For that u need to run the machine above the rated speed
