An induction motor is so-called because the currents circulating in the machine's rotor are due to voltages induced into the rotor conductors through 'transformer action' from the field windings located on the stator. In other words, there is no external electrical supply to the rotor which, instead, behaves in a similar manner to the secondary winding of a transformer.

What is meant by the term site induction?
What is meant by the term "Induction"?It means they show you the safety rules, where the assembly points are, what protective equipment you need to wear.....it is the law to have an induction before you can start work
What is an Induction Machine?
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.Reference: Wiki Answers
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 frictional losses of the induction machine linear?
No, the frictional losses of an induction machine are not linear. Friction losses increase with speed and are affected by factors such as temperature, lubrication, and surface finish. These losses are typically represented as a quadratic function of speed in machine modeling and analysis.
Are the friction losses of the machine linear in induction motor electrical machines?
yes
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.

Are the friction losses of an induction machine linear?
No, the friction losses of an induction machine are not linear. These losses are typically influenced by factors such as speed, load, and temperature, which can make the relationship between friction losses and operating conditions non-linear.
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.
