3 Model description
The motor model is composed of the product code and the specification code in order according to the provisions of GB4831. Product code by motor series
The code indicates that the meaning is as follows
JK—— Squirrel-cage rotor high-speed three-phase asynchronous motor JS, JS2— Squirrel-cage rotor three-phase asynchronous motor JR, JR2— Wound rotor three-phase asynchronous motor JSL—— Squirrel-cage rotor vertical three-phase asynchronous motor JRL— — Winding rotor vertical three-phase asynchronous motor
The specification code consists of the frame number, the serial number, the core length serial number, and the number of poles.
