If you are talking about a switch that is used to change the direction that a single phase motor turns from clockwise to counter clockwise, the switch is called a forward - reverse drum switch.
By reversing any two of the three phase legs that feed the 3 phase motor.
<<>>
On a single phase motor a drum switch is used. This switch reverses the start winding so that when voltage is applied to the motor it will revolve in the reverse direction.

How do you wire a single pole motor 110 volt switch?
The switch will be wired in series with the motor. It is connected between the supply voltage and the motor's junction box. The switch will break the black wire while the white wire is just wire nutted together and is carried directly through to the motor.
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 is the necessity of the starter.Can a single pole switch replace it?
A motor starter usually has an overload heater incorporated into it. A single pole switch does not have that type of protection. There are many brands of fractional motor starter switches. These types of switches are sized by the motors full load amperage. These types are dual purpose being that they can be used as the motors isolation switch and also they can be used as motor protection for the connected motor.
Can a single pole switch replaced starter?
If you are talking about motor control then the answer is yes. There are two things to take into account though. One, is the motor thermally protected. This is for overload protection. On fractional HP motors it will indicate this on the nameplate. If the motor is not protected, then a fractional HP motor switch should be used. Incorporated into this switch is a heater element that the motor current flows through. If the motor current gets over the motor nameplate rating then the heater trips the switch and shuts the motor off. The other thing is that the switch has to be motor rated, currents and voltage matching the motor nameplate ratings. The specific switch has been designed to open motor currents under full motor loads. An ordinary house light switch is not motor load rated and should not be used for this purpose.
How do you change rotation of 6K709C dayton jet pump motor?
Interchanging the red and black leads in the motor's motor junction box will reverse the direction of rotation on the motor.
Switch that regularly reverses the current in some motors?
A switch that reverses the direction of the current in a motor is called a forward reverse drum switch. It is a single phase motor that turns from clockwise to counter clockwise.
To reverse the rotation of a three phase motor you would?
Switch two of the three wires.
How do you forward direction on a single phase induction motor?
A motor does not have a forward or reverse direction like a vehicle. Electrical terminology is clockwise or counter clockwise rotation determined by looking from the opposite drive end of the shaft. That said, a split phase induction motor 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's directional rotation can be changed by reversing the connections of either the start winding or the run winding but not both.
What is the definition of commutator?
A commutator is an electrical switch that periodically reverses the current direction in an electric motor or electrical generator. A commutator is a common feature of direct current rotating machines.
How do you wire a single pole motor 110 volt switch?
The switch will be wired in series with the motor. It is connected between the supply voltage and the motor's junction box. The switch will break the black wire while the white wire is just wire nutted together and is carried directly through to the motor.
How is direction of rotation for single phase induction motor determined?
A single phase induction motor is not self starting; thus, it is necessary to provide a starting circuit and associated start windings to give the initial rotation in a single phase induction motor. The normal running windings within such a motor can cause the rotor to turn in either direction, so the starting circuit determines the operating direction.
How do you change a direction of a motor?
DC motor: Switch your leads. AC single phase motor: Direction cannot be changed. The motor will run the same direction regardless of how your leads are terminated. AC 3 phase motor: Switch any two leads.
What is a reversing switch that rotates with the coil in am electric motor and reverses the direction of the current every half turn?
It's called a 'split-ring commutator'. It changes the naturally-produced a.c. into d.c.
How can you reverse the direction of rotation in an induction motor?
A single phase induction motor 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.

How do you change rotation on a Century AC motor?
There are two alternate methods depending on whether the motor is single phase or three phase. On a single phase motor, reverse either the start winding coil lead or the run winding coil lead but not both. This action will reverse the motor's rotation. On a three phase motor, interchanging any two of the three coil leads will reverse the motor's rotation.
