DS/EN 61377-3:2003 Railway applications - Rolling stock - Part 3: Combined testing of alternating current motors, fed by and indirect convertor, and their control system
This International Standard applies to the combinations of motor(s), convertors (direct or indirect) and their control system and its object is to specify: - the performance characteristics of electric drives consisting of an convertor, alternating current motors, and the related control system; - methods of verifying these performance characteristics by tests. Two categories of combined systems can be considered: - 1) Alternating current motors fed from an inverter without any control between the mechanical output (torque, speed) and the convertor itself (mostly auxiliary motors, for example cooling fan motors). The motor works exactly as if it were fed fr
