The efficiency classes for motors are subdivided according to IEC 60034-30-1 into the classes IE1 to IE4. The values refer to the operating point 100; 100, i.e. 100 % speed and 100 % torque. Motor manufacturers are not obliged to specify the loss values at all operating points. Bauer assists its customers and gives the loss values of its permanent magnet synchronous motors, so that they themselves can determine the overall losses and – as previously – proceed with their system optimisation and protect their core knowledge.
