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.
The answer to that question is entirely dependent on the motor. Many motors have an access plate where the power feeds into the motor. Removing that plate often reveals a wiring diagram that shows how to change the wiring to reverse the motor direction. But most AC electric motors do not provide the option of reversing 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.
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.
The direction of a singular phase induction ac motor can be reversed by switching the capacitor in relation with the motor windings. When started in the reverse direction, the motor will maintain the same torque level that it had in the forward direction.
A synchronous motor will spin at the system frequency. 60 Hz translates into 60*60 = 3600 direction changes per minute. If this is a two pole motor (one north and one south), it will spin 1 rotation per direction change. If it is a four pole motor (two north and two south), it will spin 1/2 rotation per direction change. If this is an induction motor, it will spin at a frequency slightly less than an equivalent synchronous motor; this frequency difference is referred to as slip.
by changing the ryb phase altornat e.g. rby ,bry , yrb we change the direction of the induction motor .. . ..

Reverse any two line leads connected to the motor will reverse the directional rotation of the motor

Interchanging the red and black leads in the motor's motor junction box will reverse the direction of rotation on the motor.
yes by reversing phases
a) Change the direction of current flow through the fields DEC

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.
The direction of impulse for motor neurons is away from the brain.
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.
