Squirrel Cage motor is a kind of Induction Motor. The reason an induction motor sometimes refered to a rotating transformer is because the stator (Primary windings in a transformer), which is powered to set up a magnetic field induces a current in the armature coils (secondar coils in a transformer). However, instead of giving an electrical power output, the coil is short circuited to produce mechanical output (torque in this case)

When will a synchornous motor acts as an induction motor?

If there is an extra winding called the "damper winding" in addition to the field winding.Then the synchronous motor will operate as a squirrel cage induction motor.Whats is a damper winding ?A damper winding is made up of copper bars which are placed in the slots in the pole faces of the rotor.These are short circuited with the help of end rings in a squirrel cage induction motor.


What can cause the 2000 Toyota Sienna power door locks fuse to keep blowing?

It could be short-circuiting or intermittent short-circuiting of wires to the power door motor.09/22/10--- take it to a body shop, have them reprogram the power door computer for $75 Toyota gave me BS about needing to replace everything for over $1000.


How do you start a single phase slip ring induction motor?

a single phase motor must have at least 4 poles one set is connected to the line the other is connected in series thru a capacitor or inductor to shift phase and set up a rotating magnetic field the rotor usually has a squirrel cage that will start turning the slip rings can have different purposes depending on how the rotor is wound if the highest rpm of the motor is a multiple of the line frequency 3600RPM for 60Hz 2 pole you apply dc to the winding to make it synchronous. if the hi speed of the motor is 3470RPM the squirrel cage is weak and you must short the rings to get up to the high speed there is beauty in this in that if you vary the resistance from short to open it will be a variable speed motor

Why is it not possible to insert the external resistance in the rotor circuit in a cage induction motor?

A squirrel-cage rotor consists of uninsulated copper or alumnium bars, short-circuited by rings located at opposite ends, and semi-enclosed within a laminated iron rotor, and there is no provision for any form of external connection. So it would be quite impractical to do what you suggest.

Which device provides short circuit protection?

A fuse protects a circuit from short circuiting. Also a breaker is used for this same purpose with the additional advantage of protecting the circuit from overloads also.
