scope:
This part of IEC 61377 applies to the combinations of motor(s), inverter and their control system, and its object is to specify:
− the performance characteristics of electric drives consisting of an inverter, alternating current motors, and the related control system;
− methods of verifying these performance characteristics by tests.
Two categories of combined systems can be considered:
a) alternating current motors fed from an inverter without any control between the mechanical output (torque, speed) and the inverter itself (mostly auxiliary motors, for example cooling fan motors). The motor works exactly as if it were fed from a busbar (at variable frequency and voltage or not);
b) alternating current motor(s) (paralleled or not) with a control between the mechanical output and the inverter.
