TABLE OF CONTENTS Most of the motors (movable units) in this book are assumed to be viewed from the West side with the coupling end pointed North. From a personal standpoint, this is for the ease of writing and is hopefully for the ease of understanding by the reader. Refer to FIGURE (1). In FIGURE (1) you are viewing the motor from an elevated position just Northwest of the motor. The horizontal and vertical planes are (in reality) quite invisible; as is the centerline of the motor shaft. But the quite real existence of all three must be understood.
Very often in this book, mention is made about a move in the horizontal or vertical planes.
| Note | Rule of thumb: with just any old conventional motor in mind, if it s a shim move, it s a vertical move in either the up or down direction through the vertical plane. |
| Note | Rule of other thumb : With just any old conventional motor in mind, if it s a lateral move it s a move in either the North, South, East or West directions through the horizontal plane. |
| Note | And if you can spare one more thumb: Regard the horizontal and vertical planes as intersecting along the centerline of the movable unit shaft axis; that is as long as the subject matter involves just any old conventional motor . Think about it; if it s a vertical mounted motor, the rules have to change to the tune of about 90 ! |
In FIGURE (1) visualize the East/West...
