Subject content and scope of application
This standard specifies the model compilation rules for permanent magnet generator products JB/T6711-1993
This standard applies to permanent magnet generators on small tractors, agricultural transport vehicles, construction machinery and their diesel engines. Model compilation method
Model composition
Variant code
Power code
Product code
2.2 Product code
Use the initials of 2 to 4 Chinese phonetic letters, where YF represents the "Yong" and "Fa" of permanent magnet generator, and the meanings of the last two letters are shown in the table below.
Voltage level
Pulley permanent magnet generator
Through-shaft pulley permanent magnet generator
Inner rotor flywheel permanent magnet generator
Outer rotor flywheel permanent magnet generator
Fan permanent magnet generator
Disc permanent magnet generator
XX type DC permanent magnet generator
The nominal voltage of the permanent magnet generator is 12V, without voltage level code. 2.4 Power code
Pulley type does not have additional code
T-"Through" shaft pulley type
N-"Inner" rotor flywheel type
W-"Outer" rotor flywheel type
F_"Wind" fan typebzxz.net
P"Disk" type
z-"Direct" flow
The tail number below 60W can be 0 or 5: The tail number above 60W The rated power (W) of the generator is expressed in 2~3 Arabic numerals. All are 0.
The permanent magnet generator with DC output is expressed according to the DC output power after rectification. 2.5 Variant code
When the main electrical parameters and basic structure of the product do not change, it is generally called a variant according to the different installation dimensions and some local changes in the structure. It is indicated by capital Chinese phonetic letters A, B, and C, but the three letters "}", "O\", and "Z" are not allowed. Approved by the Ministry of Machinery Industry on July 29, 1993
