Foreword
JB /T5867-2004
This standard is a revision of JB/T5867-1991 "General Technical Conditions for Coreless Electric Hydromagnetic DC Servo Motors". Compared with 3B/T5867-1991, the main changes in this standard are as follows: The standards cited in IB/T5867-1991 are GB/T2806 "Method for determination of motor noise", GB/T5872 "Technical conditions for packaging of control micromotors", GB/T7345 The "Basic Technical Requirements for Controlling Micromotors" has been completely revised, and this standard now refers to its revised version.
-The text symbol "SN\" in the electrical schematic diagram in JB/T5867--1991 is not the standard text symbol for DC servo motor, and is now changed to \SM".
4.3.2 in JB/T5867--1991 stipulates that "the appearance and installation dimensions shall comply with the provisions of 3.2", which is now changed to "should comply with the special technical conditions". Since 3.2 specifies the basic appearance and structural type, special structural types should be allowed to meet user requirements. 4.5 "Forward and reverse speed difference" in JB/T5867-1991 is now changed to "forward and reverse speed difference" because "forward and reverse speed difference" has been defined in GB/T2900.26 "Electrical Terminology for Controlling Motors" , the meaning in this technical condition does not conform to its definition and will no longer appear after the revision of 5.1.3 "Stable Temperature" in JB/T5867-1991. Because it has been defined in GB/T2900.26 "Electrical Terminology for Controlling Motors", GB/T7345 was originally cited, but this clause no longer appears in the revised GB/T7345-1994. There is no "electromagnetic disturbance" requirement in JB/T5867-1991. This requirement is added in this revision. Only the "electromagnetic disturbance" index is listed, and the "immunity" index is not included because this type of motor does not require requirements. This standard replaces JB/T5866-1991.
Appendix A and Appendix B of this standard are normative appendices. This standard is proposed by the China Machinery Industry Federation. This standard is under the jurisdiction of the National Micromotor Standardization Technical Committee. This standard was drafted by: Xi'an Micromotor Research Institute, Shanghai Aiyiqi Industrial Co., Ltd., and Beijing Shuangshan Technology Co., Ltd. The main drafters of this standard: Min Lin and Yu Ying. The previous versions of the standards replaced by this standard are: JB/T5876—1991.
