What else can I help you with?
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.
Can you change the direction on an ac motor?
A series DC motor can be thought of as having two components, the rotor and the stator. The rotor has windings which rotate and the stator's windings stay stationary. In a series DC motor these windings are connected in series. To make the motor turn backwards you must reverse the current through either the rotor or stator windings, but not both.
What is an ac motor?
An AC motor is an electric motor that runs on alternating current, like household electricity, as opposed to a DC motor that runs on direct current from a battery. Most AC motors work from the mains supply, which has a frequency of 50Hz in the UK and 60Hz in the USA. Other types are available that work like stepper motors and need a specialist supply to run them.
How do you rotate a shaft?
I presume you are talking about how to change the direction of rotaion on an electric motor. To change the direction of a three phase motor, switch any two wires of the three phase feed, and the motor will rotate in the opposite direction.
Can you change the stator direction of 3 phase squirrel case motor?
yes by reversing phases

How do you reverse the direction of rotation of a ceiling fan by changing the connections?
You can't. All single phase motors can only rotate in the direction in which they were manufactured. That is either clockwise or counter-clockwise. Only three phase motors can be reversed by changing the connections. Most ceiling fans have two sets of wiring in their motors so that a direction switch determines which way the fan rotates.
Give three reasons why AC three-phase system is used universally in the electricity public utility supply?
1. 3 phase is more efficient for electric motors. 2. Electric motors start easier with 3 phase. 3. Less current draw 4. Less heat is produced that is waste.

What is done to revers direction of a three phase electric motor?
To reverse direction, swap any two hot wires.
Why would three phase be used instead of single phase?
Three phase electricity is used instead of single phase for industrial situations. Industries use three phase electricity instead of single phase to operate electric motors driving heavy machinery. Three phase electrical motors produce more power from the same amount of electricity and maintain steadier speed. Small portable motors such as drills and mixers use single phase. Motors used around the house are single phase. Motors used to run large industrial machines use three phase.
What are three phase motors?
Three phase motors are motors which operate under three phase supply.Each phase is displaced from one another by 120 degrees.It produces three fluxes which are also 120 degrees displaced.
What does P1 stand for in electrical wiring?
P1 is where you hook L1 on electric motors. Typically used on 220v motors in the wiring diagram. P1 (phase 1) gets connected to L1 (power leg)
Which statement gives the relationship between the waves in the electric and magnetic fields in an electromagnetic wave?
In an electromagnetic wave, the electric and magnetic fields are perpendicular to each other and oscillate in phase. This means that when the electric field reaches its maximum strength in one direction, the magnetic field will also reach its maximum strength but in a direction perpendicular to the electric field.
What would cause an electric motor to run backwards?
Motors running backwards: A DC motor wired backwards or magnetic field reversed. A 3 phase AC motor with 2 phases reversed A single phase motor will run either way unless it is 'persuaded' by means of a shaded pole or other method to rotate in a particular direction.
