Full analysis of motor models: what do the letters and codes mean?

Understanding the motor needs to start with the model of the motor. Among the many types of motors, it is very necessary to be able to judge at a glance what type of motor it is, what place it is used for, and the basic motor parameters. These things are actually not that difficult, and we will explain them in detail next:

Generally speaking, the motor model consists of four parts: product code, specification code, special place code, and supplementary code.

Meaning of model code:

Y- represents "asynchronous" motor;

B- represents "explosion-proof", YB represents explosion-proof asynchronous motor;

A- represents "increased safety" type explosion-proof motor, YA represents increased safety asynchronous motor, YB belongs to "explosion-proof" motor;

K- represents "air" cooling, such as YKK, which represents an asynchronous motor with ambient cooling for both primary and secondary cooling medium in the motor enclosure.

S- represents "water" cooling, "transport" motor, such as YBKS represents explosion-proof motor with internal air cooling and water cooling system as the cooler;

YBS is a dedicated explosion-proof motor for conveyor belts.

R- represents "winding" rotor motor, such as YR belongs to wound rotor asynchronous motor;

P- represents "shielded", such as YP belongs to a shielded asynchronous motor;

L- represents "vertical", such as YL belongs to the vertical asynchronous motor;

J- represents "hoist" motor, such as YBJ refers to explosion-proof motor specifically designed for hoists;

F- represents "ventilation" and "dust", such as YBF represents an explosion-proof motor for fans, YFB represents an explosion-proof motor for dust;

T- "ventilation", "synchronous"; T, TK represents synchronous motor.

W represents "spark-free", brushless excitation, such as YW represents spark-free three-phase asynchronous motor, TAW represents increased safety brushless excitation synchronous motor.

GB- represents a "pipe" pump, such as YBGB represents an explosion-proof asynchronous motor for the pipeline;

PT- represents variable frequency speed regulation.

Explanation of explosion-proof motor model

For example:

YBX3 explosion-proof motor model:

YBX3-132M2-6F represents the meaning of the code

Y- represents: asynchronous motor

B- represents: explosion-proof

X- represents: high-efficiency energy-saving type

3- represents: the design number, 3 represents the third design

132- represents: the center height of the motor base (132mm)

M- represents: the length of the motor base (M represents medium length)

2- represents the length of the 2nd core

6- represents: number of poles (6 poles)

F- represents: special environment code (corrosion-resistant type)

B3 installation mode: foot connection

B5 installation mode: flange connection

B35 installation mode: foot + flange connection

It is worth noting that all models are composed of Chinese spelling letters. It is very simple to understand and remember the types of motors installed. Now, do you have a better understanding of motor models?

Understanding motor models can indeed simplify the process of identifying motor types and their applications. The breakdown of the model code into distinct parts provides a clear indication of key features such as motor type (e.g., asynchronous or synchronous), special characteristics (e.g., explosion-proof or increased safety), cooling method, and installation mode. By familiarizing oneself with these codes, one can quickly determine the suitability of a motor for a particular use case, making selection and integration more efficient. This knowledge also facilitates communication within the industry, as professionals can easily decipher and convey motor specifications using standardized model codes. Overall, grasping motor models enhances comprehension and facilitates informed decision-making in various engineering and industrial contexts.
