3.2.4.  Efficiency curves 

 

 

 

 

Caution: The efficiency curves are typical values. They may vary from 
one motor to another. 

 
 

 

 

 

Caution: The efficiency curves are given for an optimal motor control (no 
voltage saturation and optimal phase between current and EMF) 

 
 

 

 

 

Caution:  The efficiency curves do not include the losses due to the 
switching frequency.
