No, unless it is a three phase motor and you reverse only two of the phases.
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.
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.
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.
it has very high speed but no load
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.
Reverse the polarity of armature windings of the motor.
DC shunt motor can be reversed by changing the polarity of either the armature coil or the field coil.
No. Motors can be run in either direction, clockwise or counter clockwise. However, mechanically spinning an electric motor will generate electric power.
a general purpose D-C motor can be reversed by changing the polarity of either the armature or the field but not both

Change the polarity of either the field coils or the armature, not both and you will reverse rotation.
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.
DC shunt motor can be reversed by changing the polarity of either the armature coil or the field 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 need an even number of them to offset... 4 of them would be too much for the motor to handle.
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 alls good thanks for the help
