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.

Can you use a 3 phase radial arm saw on 240V?

You cannot use a 3 phase motor on single phase power. It will be limited in it's torque output, if it starts at all. The best thing to do is put the 3phase motor up for sale on eBay and buy a replacement single phase motor. If that is not an option you can get a converter, but they are expensive. Don't try to wire a 3 phase motor up to residential 220 if you don't know exactly what you are doing. Chances are you will burn your motor up.


When you have 56KVA available in 3 phase supply how much is your available current in 3 phase and how much in 1 phase?

In three phase: I = (three phase VA) / (sqrt(3) x (phase to phase voltage)) for single phase: I = (single phase VA) / ((phase to neutral voltage)) keep in mine three phase VA = 3 x (single phase VA), and phase to phase voltage = 1.732 x (phase to neutral voltage) Therefore the single phase and three phase currents are the same (ie, the three phase currents are the same in all three phases, or balanced). But don't get available current and available power confused (KVA is not the same as KW).


Can you use 3 phase circuit as 3 separate single phase circuit?

yes we can use as a single phase circuit because at practise directly the 3-phase circuit is made by combining the three single phase circuits


What you basically want is will each phase take 26 Amps current for 15HP 3 phase 415VAC motor?

Yes. In a 3-phase motor, all 3 phases have the same current.


Why capacitor is used in ceiling fan?

Capacitor helps a motor generate a starting torque. once the torque is produced and motor rotates capacitor acts as a current path. technically capacitor creates a phase difference.

Why three phase induction motor has uniform torque?

The 3-phase currents in the 3 coils of an induction motor will produce a steady rotating magnetic field.


Why does a three phase system provide 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.

Disadvantages of 3 phase induction motor?

One of the disadvantages of the 3 phase induction motor is that it requires a three wire supply. The other disadvantage is that the 3 phase induction motors have poor starting torque and high have in the rush currents.


What are the advantages of three phase motor over the single phase motor?

A 3-phase motor produces a steady torque that does not pulsate. A 3-phase motor starts turning in the right direction when switched on without the need for a separate starting winding.


What type of motor is used in centrifugal pump?

3 Phase induction motor because it produce high torque at starting


How do you increase starting torque in cage type 3-phase induction motor's?

by adding external resistance to the shaft of rotor


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
