Applies to the combinations of motor(s), chopper and their control, and its object is to specify a)the performance characteristics of electric drives consisting of a chopper, direct currentmotors, and the related control system b)methods of verifying these performance characteristics by tests.In traction drives, a combined system with chopper and direct current motor(s) without any control between the mechanical output and the chopper is not usual. It is not, therefore,considered in this standard. IEC 60349-1 applies to chopper-fed direct current motors, IEC 61287-1 to power electronic convertors, and IEC 60571 to electronic equipments.As a consequence, IEC 60349-1 describes the tests to demonstrate the compliance of the motor to its specification, while IEC 61287-1 does the same for the chopper.
