You can lower amperage by reducing the load on the motor (how much work it does), also you can increase the voltage, but the motor must be wired for the voltage increase or it will burn up.

Why 2 phase induction motors are not used in industries?

A two-phase* system is archaic, and has been completely superceded by three-phase systems, so there is no demand for two-phase induction motors. (*A two-phase generator has two phase windings, displaced from each other by 90 degrees.)


How single-phase induction motor classified?

The single phase induction motors are made self starting by providing an additional flux by some additional means. Now depending upon these additional means the single phase induction motors are classified as: 1.Split phase induction motor. 2.Capacitor start inductor motor. 3.Capacitor start capacitor run induction motor. 4. Shaded pole induction motor.

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.


Do all single phase motors have a start and run winding?

No, commutator motors as used in vaccum cleaners for example do not use a starting winding. Single-phase induction motors need a starting winding without which they will start in either direction if given an initial twist.

How many microfarad of starting capacitor is best for 15hp 3phase motor?

Starting capacitors are only required for single-phase induction motors. They are not necessary for three-phase motors.


Revolving field theory of single phase induction motors?

The revolving field theory of single-phase induction motors suggests that a rotating magnetic field created by current flowing through two windings (main and auxiliary or starting winding) produces a starting torque in the rotor. This theory explains how single-phase motors can operate without the need for a separate rotating magnetic field, as in three-phase motors, by using a split-phase or capacitor start design to generate a rotating magnetic field.


Why you use brushes for single phase induction motors?

There no brushes in an induction motor. The rotor is independent and is a short-circuited cage of parallel bars.
