Change the polarity of either the field coils or the armature, not both and you will reverse rotation.
the direction of the rotation of dc shunt generator could be changed only by changing the direction of rotation of the prime mover
A split phase induction motor has two sets of coils and a centrifugal start switch. The start winding is in series with the start switch. The start winding provides a rotating magnetic field in one direction enabling the motor to start. The motor can be reversed by reversing the connections of either the start winding or the run winding but not both.
The motor will spin the direction that the positive lead is on. So if the shaft is pointing towards you, you will need to put the positive lead on the left side to make it turn counter clockwise.
YES. If zero is established for a system that is revolving in a certain direction and the amount revolved is required in radians, then if the direction of rotation is reversed and the system rotates beyond zero the amount becomes negative. For circumstances where a simple angular measurement is required of a static system then it would be highly unusual for a negative radian measure to be seen.
You can put the tire on the front. The rotation arrow should point the same whether it is on the front or back.
The charge on the top of the tree could be positive or negative, depends on the direction of the wind. If the wind is in the same direction of the earth's rotation around the sun, the charge is negative, and vise versa.
If you reverse the polarity in a parallel circuit, the components will still function but the direction of current flow through each component will be reversed. This could lead to a change in the behavior of any polarized components in the circuit, such as diodes or electrolytic capacitors. It is important to ensure that the components can handle the reversed polarity to prevent damage.
rotation
No. It would be a diagonal.
Reverse gear is spur because it has to slide, sliding mesh gearbox uses spur gears. Because if it was constant mesh gear (helical) it could not slide in and out, therefore it could not go in the opposite direction of rotation.
yes
To change the motion from anticlockwise to counterclockwise, you can simply reverse the direction of rotation. This can usually be achieved by adjusting the settings or controls of the object or equipment that is rotating, such as a motor or a fan. Alternatively, you could physically modify the object itself to rotate in the opposite direction.
