How can you rotate the dc series motor in both direction?
in any dc machine changing the polarity of the field will change its direction. here, in series motor, the field is in series with the armature, to which we feed the supply. hence, change the feeding polarity.
What is the difference between AC machine and DC machine?
ac machines can run only in one direction but dc machines can run in both the directions depending upon the direction of current flow into it. If we change polarity of input supply we can reverse the direction of motion of dc machineCommentThe above answer isn't altogether true, as it's very easy to change the direction of an AC machine. For example, to change the direction of rotation of a three-phase induction motor, the motor controller interchanges two of the three line conductors.The main difference used to be that the speed of DC machines is easier to control, but that is a thing of the past thanks to developments in electronic motor controllers.
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.
How can the direction of rotation of a DC shunt motor be reversed?
DC shunt motor can be reversed by changing the polarity of either the armature coil or the field coil.
How do you change over a ac motor to a dc generator?
Type your answer here... how can you change an ac motor to a dc generator
What would cause a 12 volt motor to change polairity?
This assumes you have a 12 volt direct motor. You should be able to simply reverse the wires leading to the terminals. There should be two wires going to the motor. Change them around.
How do you change an ac motor to a DC motor?
Ac motor have slip ring, to remove the slip ring,connected to the commutator its a dc motor.
When a dc motor is set in electrical neutral it will?
not run in either direction
An example of a stepper motor miniature dc motor and an ac motor?
stepper motor :- motor used for controlling direction of movement of robotic arm dc motor :- motor used in cellphones as vibrators ac motor :- motor used in textile machinery
Can a dc shunt motor be operated on ac supply?
yes.because the direction of motor is same in both half cycles
What can change an ac current to a DC current?
rectifierac motor - dc generator set
Why rotor of a dc motor moves in the anticlockwise direction?
Positive and negative are reversed. It will run either direction depending on which way it is wired.
