Introduction of JB/T 1012-2007

1 Scope This standard specifies the YY series permanent-split capacitor asynchronous motors in terms of type, basic parameters and dimension, technical requirements, test methods, inspection rules, marking, packaging, storage and transportation and warranty period. This standard is applicable to YY series permanent-split capacitor asynchronous motors (frame size 45~90) (hereinafter referred to as "motors"), and all other series motors derived from YY series permanent-split capacitor asynchronous motors may also refer. 2 Normative References The following standards contain provisions which, through reference in this standard, constitute provisions of this standard. For dated reference, subsequent amendments to (excluding correction to), or revisions of, any of these publications do not apply. However, the parties coming to an agreement based on this standard are encouraged to investigate whether the most recent editions of the standards apply. For undated references, the latest editions of the normative documents referred to apply.
