"Drive can power either constant-torque toads or those varying as the square of the speed.

be of critical importance in influencing total costs highly dependent on the terms of the rate structure applied by the power supplier.

• Operating characteristics. All the drives discussed in this section compare favorably and all are considered generally suitable to perform functionally as pump drives.

• Mechanical features include enclosure, mounting, bearing capabilities, and arrangement (horizontal, vertical). Features are highly application related.

• Mechanical simplicity is one of most importance to operations personnel. It can consist of the number of wear points (parts) in rotating and control equipment. The rationale is based on the concept that parts subject to wear are the eventual causes of failure; the smaller the number of parts, the less cause for failure.

• Heat emission—removal requirements can be critical depending on where the equipment is to be located. Heat can be emitted by both the equipment and the drive. If they are located in an enclosed area or building, heat emission can be an important issue.

In the final analysis, no simple routine can be suggested for drive selection. Each drive must be reviewed in the light of the application and its requirements. By reviewing the capabilities and features of the various drives, one has a starting point leading to successful drive selection.

The relative importance of these factors seldom remains stable but changes as application circumstances change.
