Why a three phase system provides constant torque?
It doesn't. A 3-phase motor will provides constant torque because the three alternating fields produce exactly the same effect as a single rotating field.
What is a 3 phase torque?
It is a short-hand description of the torque from a 3-phase motor. By the nature of 3-phase electricity, a motor using it gives a constant torque, unlike a single-phase motor which gives a torque that pulsates at twice the supply frequency. Usually that does not matter because there is enough inertia in the rotating parts to mask the effect.
What is phase 3?

What is the advantage of polyphase system over single-phase system?
1) less copper cross section to conduct current2) constant power to load3) constant rotating magnetic field4) Ideal for Direction Reversing5) Current is not zero at any constant..
How does the 3-phase induction motor acts like 2-phase induction motor if a phase is disconnected from supply?
yes the motor will run but will draw more current and the torque will be not constant means not smooth due to unbalanced current
When the physical state of a substance changes during a phase what happens to the temperature of the system?
The temperature remain constant during a change of phase.
What is the units of phase constant?
Unit of Phase constant is Radians per metre .
What is the purpose of capacitor in a single phase motor?
the purpose of the capacitor is to create a phase difference between main winding current and axillary winding. this would produce a rotating constant magnetic field which is required to produce the torque.
What is the difference between phase equilibrium and metastability?
For the condition of phase equilibrium the free energy is a minimum, the system is completely stable meaning that over time the phase characteristics are constant. For metastability, the system is not at equilibrium, and there are very slight (and often imperceptible) changes of the phase characteristics with time.
A change of phase takes place at a constant what?
A change of phase takes place at a constant temperature.
When modulating freq is doubled then modulating index is halved and modulating voltage remains constant system is?
It's Angle modulated system where the amplitude remains constant & frequency & phase varies with respect to modulating signal.
