What three factors determine the amount of torque produced by an AC induction motor?

Torque is produced by a phase difference between two windings. The higher the phase difference, the higher the torque.

The rotor rotates slightly slower than the magnetic field produced by the stator (the fixed winding). The difference in speed is called the slip and it allows low-frequency currents to be induced in the rotor and torque to be produced. For a motor rotating just below the synchronous speed, the torque is proportional to the slip which is defined by this, where Nis the actual speed and Ns is the synchronous speed:
s = 1 - N/Ns

What are the materials suitable for induction hardening?
High frequency of electricity is passed through a coil and is most often used in steel alloys. The amount of heat and the size of the coil will help to determine the amount of time needed for the project being undertaken.
When the induction motor working as induction generator?
An induction motor connected to an existing ac supply normally runs at less than the synchronous speed by an amount described as the 'slip' which is proportional to the torque demanded at the shaft. If the same motor is instead coupled to an engine and driven at a speed higher than the synchronous speed, with negative slip, power then travels back into the ac supply and the motor has become a generator. The amount of power produced depends on the speed. However a normal induction motor will not behave as a stand-alone ac generator. For ac power generation synchronous generators are invariably used because it is necessary to set and maintain the frequency of the supply accurately.
What determines the amount of runoff?
One of the factors that determine whether water infiltrates is the nature of the surface. Another factor that determines is the elevation of the surface or its shape.
What four factors determine the amount of resistance in a circuit?
Material that makes up the wire, length of wire, diameter of wire, and temperature of wire
Which advancement in technology helped reduce the amount of solid waste produced?
electronic mail
What factors determine the carrying capacity?
Factors that determine carrying capacity are the amount of resources available and population. Other factors are land area and amount of water.
Determinants of demand include factors that determine the amount that will be purchased at each price?
Determinants of demand include factors that determine the amount that will be purchased at each price
How is electricity produced from magnetism?
Electricity are produced from magnetism from induction. Induction is a magnetic field.
What three factors determine the amount of energy required for an activity?
the three factors that determine the energy cycle are solar power, electricity, and heat.
What two factors determine the amount or lift achieved by an airplane?
thrust and wing size determine the amount of lift achieved by an air plane.
What factors that determine the soil pH?
The factors which affect soil pH levels are the amount of rainfall, the amount of plants and the number of soil organisms.
How much wind is needed to produce 12volt dc?
It's not the amount of wind, but the design of the generator, that decides what voltage is produced. The amount of wind will determine the power produced.
What factors determine how long a star lives?
the stars amount of mass
What are the four factors that determine a persons creditworthiness?
