It was originally developed for rolling mill applications, but can also be used to advantage in hoists and comparable highcapacity drives running at slow speed. Following a brief review of the problems arising in the design of DC machines for maximum ratings, the paper describes the cycloconverterfed synchronous and asynchronous rotating ...
Cycloconverter Cycloconverter adalah rangkaian elektronika daya yang dapat mengubah gelombang masukan AC dengan frekuensi tertentu ke gelombang keluaran AC dengan frekuensi yang berbeda. Prinsip kerja cycloconverter (ac ke ac) adalah dengan menurunkan frekuensi sumber rangkaian dibagi menjadi 2 buah rangkaian konverter tyristorP dan rangkaian konverter tyristorN yang bekerja secara ...

have been manufactured and used for metal rolling main drives. The maximum value of the M constant is 2 x 106 to 3 x 106 for reversing rolling mills and 3 x 106 to 5 x 106 for nonreversing rolling mills. Figure 3 shows the technical selection criteria for single versus multiple dc motors for nonreversing rolling mills.
ACcycloconverter drives for cold and hot rolling mill applications Abstract: It is pointed out that there are several possibilities to realize an AC variable speed drive with cycloconverters. The motor can be an asynchronous or a synchronous type and the cycloconverter can be operated with or without circulating current.

network. In selecting the main drive system for rolling mills, a lot of factors should be considered. The system should adapt to technology requirement of the rolling mills such as the power, torque, speed, range of speed regulation, and so on. The overload capacity of the drive system is determined according to the maximum power of the rolling ...
Go gearless to meet your business objetives by exceeding standard availability targets in your grinding operations. ABB's GMD is the most powerful mill drive system in the market to power semiautogenous (SAG), ball and autogenous (AG) mills, This 'workhorse' for grinding operations combines a robust, servicefriendly and fit for purpose ...
Abstract: Following a brief review of the problems arising in the design of dc machines for maximum ratings, the cycloconverterfed synchronous and asynchronous rotatingfield machines with fieldoriented control as interesting alternatives to the dc drives will be described.

These types of Cycloconvertes are formed by using 3 threephase to single cycloconverters linked together to the load and is used in AC machine systems. Two basic configurations are wye and delta. Output of these converters can be connected in wye and delta. The phase of output voltages are 120 o shifted. The circuit diagram is shown below.
