DC machine
answer
In trigonometric terms and diagrams, regular terminal angle rotation is anti-clockwise. This is to keep standards universal across all diagrams.
Referring to the direction of rotation, a clockwise direction indicates rotation in the same direction as the hands move on the face of a clock. Counterclockwise rotation is in the opposite direction.
Retrograde rotation is when an object rotates in the opposite direction of its orbit. This is opposite to the more common prograde rotation, where the rotation and orbit are in the same direction. An example is Venus, which rotates on its axis in a retrograde direction compared to the direction it orbits the Sun.
the direction of the rotation of dc shunt generator could be changed only by changing the direction of rotation of the prime mover
No, you cannot change the rotation direction of an engine easily. The direction of rotation is determined by the design and placement of engine components such as the crankshaft and camshaft. It would require significant modifications to the engine's internal components to change its rotation direction.
It means that the rotation is in the opposite direction.
Spinning in a counterclockwise direction is called anti-clockwise rotation or counterclockwise rotation.
Rotation is a vector having a direction and magnitude.
The Earth's rotation axis is always oriented in a north-south direction.
The centre of rotation, the angle of rotation and, unless the angle is 180 degrees, the direction of rotation.
Axial vectors represent physical quantities associated with rotational motion, such as angular velocity, torque, and angular momentum. These quantities have both magnitude and direction, and their direction is perpendicular to the plane of rotation.
