What else can I help you with?
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.
Can cross-wiring an electrical outlet cause a household fan motor to smell like it is burning?
I think by 'cross wiring' you mean reverse polarity. This means the hot wire is connected to the neutral screw and the neutral wire is connected to the hot screw. This shouldn't have any impact on an AC motor, since AC voltage already changes polarity 60 times per second.
What determines the magnitude and polarity of the counter-emf in a dc motor?
the magnitude is decided by the amount of flux, number of conductors, speed of the motor and the type of the winding used. the polarity is decided by the direction of rotation of the motor and the direction of armature current flowing in the motor.
How speed of the repulsion motor can be reversed?
it has very high speed but no load
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.
How is a DC permanent-magnet motor reversed?
Reverse the polarity of armature windings of the motor.
In what two ways can the rotation of a shunt connected dc motor be reversed?
DC shunt motor can be reversed by changing the polarity of either the armature coil or the field coil.
Will running a motor backwards generate power?
No. Motors can be run in either direction, clockwise or counter clockwise. However, mechanically spinning an electric motor will generate electric power.
How do you Reverse direction on a DC motor?
a general purpose D-C motor can be reversed by changing the polarity of either the armature or the field but not both
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.
How could the direction of rotation of the universal motor be reversed?
Change the polarity of either the field coils or the armature, not both and you will reverse rotation.
What happens if the direction of current at the terminals of a series motor is reversed?
No changes will occur by wiring a 110 volt motor in reverse polarity, rotation will always be the same. Some single phase motors are designed to be reversed ,but that is a function of the relationship of start windings and capacitors and requires some wiring changes in a motor junction box or an end terminal housing, not by just changing the incoming power.
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.
Why does the rotation of the motor reversed when change the polarity across the main winding coil?
When changing the auxilary face winding connection the current flow in the winding is changed so that the rotating emf direction is changed . Thats why the motor rotates in opposite direction.
You put 3 12v batteries in a golf cart 2 of them reversed polarity how do you stop this from happening?
You need an even number of them to offset... 4 of them would be too much for the motor to handle.
If the live and neutral connection in an electric meter are reversed does the meter rotate reverse?
In some cases yes, but it depends on the motor's application (use). For example, the electric motor in a batery-operated toy car will turn backwards if you reverse the polarity. Other more complex motors won't work at all, or can be damaged if you reverse the polarity. it is an AC motor that runs the Wattmeter, it is all about the direction of current flow to make the meter run backwards you would need to swap the incoming active and the incoming neutral with the outgoing active and the outgoing neutral, thereby reversing the meter. reversing the Active and Neutral does nothing because they already are swapping between themselves at 50 times a second or 60 depending on your location. Also if you put more current into your supply than is being draw by it then the meter will also spin backwards. eg: overdriving it with a generator.
The magnets in motor were backwards?
the magnets in motor were backwards alls good thanks for the help
