What is the effect of starting torque and power factor on double cage and deep bar cage 3phase induction motor?

In double cage and deep bar the tarting torque increases due to skin effect in the rotor wire. So the rotor circuit draw less current than simple circuit that draw around 7-8 times the rated current on starting.
Due to skin effect the rotor resistance increases and it provide maximum torque at low speed.

What is the effect of increasing number of poles on the speed of an induction motor?
As the number of poles (P) increases, the speed of an induction motor (N) decreases. As seen by the formula: N=(120*f)/P
What is effect of frequency on induction motor speed?
secret......... They are proportional..
What is double cage rotor and deep bar cage rotor?
deep bars in the rotor that result in higher rotor resistance at low speeds thus resulting in larger starting torques. The higher resistance is due to the skin effect.

How do you use the word induction in a sentence?
I came to this conclusion using inductive reasoning. The inductive effect by the wire can create a static charge in the metal case.
What is the effect of induction motor on power factor?
An induction motor has a lagging power factor. Motors of more than about 2 HP are designed to have a power factor of 0.85 or higher.
What is the effect of increasing number of poles on the speed of an induction motor?
As the number of poles (P) increases, the speed of an induction motor (N) decreases. As seen by the formula: N=(120*f)/P
What is mutual induction effect?
when the current flow through primary coil an electromotive force generated to secondary coil in the direction that prevent the magnetic flux in the primary coil is called mutual induction.

Does double summon effect last the whole duel?
Double Summon's effect is only active during the turn in which you activate it.
What is the derivation of Torque and power equation of induction motor?
Torque is the cross product of radius and force .Torque is a twisting effect. Torque is the cross product of radius and force .Torque is a twisting effect.
What are the End effects in linear induction motor?
due to the finite length of primary core and windings of linear induction motor, the phenomenon so produced is called as end effect. this can be categorized further as dynamic end effects and exit end effects.
