If it is a three phase motor just interchange any two of the three wires. If it is a single phase motor, which is also known as a split phase induction motor, it has two sets of coils and a centrifugal start switch. The start winding is in series with the start switch. The start winding provides a rotating magnetic field in one direction enabling the motor to start. The motor can be reversed by reversing the connections of either the start winding or the run winding but not both.

Can you reverse the wiring to make the fan reverse?
Yes if it's a dc motor with a permanent magnet field, or if it's a 3-phase ac motor. No if it's a single-phase ac motor or a dc motor with a field winding in series or parallel with the armature. <<>> Single phase AC motors can be reversed by using a reversing switch. Reverse either the start winding or the run winding connections but not both.
How do appliances work if AC reverses direction?
AC current alternates polarity back-and-forth continually, by definition. Therefore, it is not possible to reverse AC direction. It is DC current that is directional such that when it's polarity is reversed the motor responds by turning in the opposite direction.
How can rotation be change of single phase motor?
With the starting winding disconneted the motor will start up in whichever direction it is spun. To make the starting winding operate the other way, it needs an inductor in series insead of a capacitor. Details depend on the motor, but the reactance of the inductor should match that of the capacitor.
What happened to electron under ac voltage and dc voltage?
when electrons flow under AC they flow in both direction firstly forward then in reverse and it does this for as long as there is a potential difference applied to the circuit. under DC the current only flows in one direction only
What is the value of capacitor for 1hp ac motor?
The value of the capacitor for a 1hp AC motor depends on the specific motor design and manufacturer guidelines. It is important to consult the motor's documentation or contact the manufacturer to determine the correct capacitor value for proper motor operation.
Reverse direction of singlr phase ac induction motor?
The direction of a singular phase induction ac motor can be reversed by switching the capacitor in relation with the motor windings. When started in the reverse direction, the motor will maintain the same torque level that it had in the forward direction.
Reverse direction on a 480 ac motor?
Reverse any two of the lead wires at the motor junction box.
Can you reverse the wiring to make the fan reverse?
Yes if it's a dc motor with a permanent magnet field, or if it's a 3-phase ac motor. No if it's a single-phase ac motor or a dc motor with a field winding in series or parallel with the armature. <<>> Single phase AC motors can be reversed by using a reversing switch. Reverse either the start winding or the run winding connections but not both.
How do you reverse single phase ac motor to generator?
how reversing an ac single phase induction motor to wark as induction generator
How do you reverse polarity on ac motor?
Reversing polarity is not possible with an ac motor. Some do have wiring that will allow you to change rotation. The type and model of the motor can tell you if it is reversible.
What happens when ac supply given to dc motor justify?
The motor will slightly oscillate if its enough voltage but will not run properly as the voltage is changing phase. So the motor is trying to go forward and then reverse say 60 times a second if its hook to a wall socket.
Will an ac motor run backwards if polarity is reversed at the outlet?
No, unless it is a three phase motor and you reverse only two of the phases.
High power motor is AC or DC motor?
Either or Both - AC and or DC motor's are both rated by Horsepower / RPM / Torque, DC Motor's are more commonly used where you need to reverse the rotation on the fly (by a button push) - Crane's for example.
What is the behavior of a forward and reverse biased diode?
Forward Resistance:def: It is resistance offered by diode to the forward bias is known as forward resistance.This resistance is not the same for the flow of DC as for the changing current. Accordingly this resistance is of two types :1. DC FORWARD RESISTANCE.2. AC FORWARD RESISTANCE.1. DC forward resistance: It is the opposition by diode to the DC. It is measured by the ratio of DC voltages across the diode to the resulting DC current through it.2. AC forward resistance: It is the opposition offered by the diode to the changing current. It is measured by the ratio of change in voltage across diodes to the resulting change in current through diode. The AC forward resistance is more significant as the diodes are generally used with alternating voltage.Reverse Resistance:def: The resistance offered by the diode to the reverse bias is known as Reverse Resistance. It can be DC reverse resistance or AC reverse resistance depending upon whether the reverse bias is direct or changing voltage. Idealy the reverse resistance of a diode is infinte however in practice the reverse resistance is not infinite because for any value of reverse bias, there does exist a small leakage current. It may be emphasized their that reverse resistance is very large compared to the forward resistance.These Definitions are from PRINCIPLES OF ELECTRONICS by V.K MEHTA and ROHIT MEHTA
Circuit diagram to operate ac machine in forward and reverse direction?
The word you are looking for is Drum Switch. Google it and there are many diagrams.
How does a DC brushless motor work?
To state it simply, a DC brushless motor is not a DC motor. It is an AC motor with an inverter (or electronic commutator) on the front end to make the AC, so you can use a DC input.
Where did Nikola Tesla make the ac motor?
In new york in 1844
