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 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.
Reverse direction on a 480 ac motor?
Reverse any two of the lead wires at the motor junction box.
Can small permanent magnet motors be reverse direction if the direction of current flow to the motor is reverse?
Permanent magnet field motors. With a these motors, a permanent magnet is used to replace the field coil. DC power is connected via the brushes, to the armature only. Reversing the polarity, will cause the motor to reverse its direction of rotation. It is very common to use a switch to intentionally reverse to the polarity, to allow reversal of the motor if desired.
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.
Which current is having high polarity?
ac(Alternating Current ) has the high polarity.
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.
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 is a DC permanent-magnet motor reversed?
Reverse the polarity of armature windings of the motor.
Is the actuator motor on all wheel drives a reverse polarity motor?
yes sir
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 does current flow in a nonreversing motor?
If you are talking polarity. DC motors automotive application run poss to neg. But any dc motor can reverse by changing polarity.
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.
Reverse direction on a 480 ac motor?
Reverse any two of the lead wires at the motor junction box.
What can reverse magnetic polarity make?
What can reverse magnetic polarity
Can you reverse the polarity of AC and DC?
We have the capacity to reverse the polarity of a DC voltage, at least as regards what we apply it to. When we consider a DC motor, like, say, the ones in the little "robot wars" we see on TV, the motors can be run in reverse by reversing the polarity of the applied DC voltage. We normally consider AC as already reversing its polarity. It is, after all, AC, which is alternating current. The current alternates because the voltage alternates. We'll avoid any further discussion of the polarity of AC voltages here and leave it at that.AnswerThe problem, here, is that 'polarity' has several different meanings.Polarity, in the sense of 'electric charge' cannot really be applied to a voltage (potential difference) although it can be to a potential (although the polarity is relative; it depends on the point of reference).Polarity, in the sense of 'direction', can be applied to a voltage. For example, is the voltage acting clockwise or counter clockwise around a circuit?Polarity, in the sense of 'connection', can be applied to a voltage. For example, it's important that the line conductor is connected to the centre terminal of an Edison lamp holder or to one or other of the slots in a receptacle (power socket).
