Abstract:

This guide provides the required basic ordering information for low voltage (1000 VAC or less, and up to and including motors of 500 hp) general-purpose (GP), commercial, universal, small and medium sized alternating current electric motors intended to drive common shipboard mechanical machinery such as fans, blowers, centrifugal and screw pumps. This guide does not address the ordering information for special-purpose (SP) motors, definite-purpose motors (for example, cryogenic service), or motors for use in hazardous (classified) locations as defined by the National Electrical Code (NFPA 70). The ordering checklist shall provide the following minimum information: electrical input; speed; power; enclosure; duty cycles; ambient temperature; insulation class; design class; service factor; drive method; mounting arrangement; mounting flange (end shield); rotation; motor conduit box location; closed-coupled; efficiency; and other special requirements.

Scope:

1.1 This guide covers the required basic ordering information for low voltage (1000 VAC or less) general-purpose, commercial, universal, small and medium sized alternating current electric motors for shipboard use, up to and including motors of 500 hp.

1.2 The electric motors covered by this guide are general-purpose (GP) motors intended to drive common shipboard mechanical machinery such as fans, blowers, centrifugal and screw pumps.

1.3 This guide is not intended to be used to order special-purpose (SP) motors or definite-purpose motors (for example, cryogenic service) or motors for use in hazardous (classified) locations as defined by the National Electrical Code (NFPA 70).

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use.
