Seeking help regarding motor energy efficiency

Thread Content

What do Y, E, and 3 represent in YE3 and YE5 motors? Are there energy efficiency requirements for variable-frequency motors? If so, how are they specified?
Reply #22022-01-05
Y is the motor series code; E3 denotes a 3-level energy efficiency rating. Variable-frequency motors are not subject to any energy efficiency requirements. Currently, the GB18613-2020 standard is in force
