scope:

This Standard relates to Motors, Torque, d.c. hereinafter referred to as torque motors. It is not complete in itself but shall be read in conjunction with Defence standard 61-14 (part 1), 'precision instrument, rotating servocomponents, Part 1: General requirements and common tests', hereinafter referred to as Def Stan 61-14 (Part 1), in which the latter shall be regarded as forming an inherent part of this document

This Standard requires that all torque motors complying with it and having the same type designation shall be physically, mechanically and electrically interchangeable. It specifies all the characteristics which are of importance in using these components and gives information on, or states the requirements for, those attributes which are relevant to d.c. torque motors:

-Definitions, terms and conventions

-Type designation and marking

-Test requirement and methods of test

-Nature of test equipment

Physical and performance requirements for individual types of standard torque motors are given in the relevant Supplementary Detail Sheets associated with this document.

NOTE: performance figure and their limits stated in the relevant supplementary Detail sheet are based on a close tolerance power supply and on test conditions which are strictly controlled. Under service conditions, these figure may be modified by the effects of power supply variations and of environmental conditions.
