Jun 14, 2018 cycloconveters are extensively used for driving large motors like the one used in rolling mills, ball mills cement kils etc. the out frequency of a cycloconverters can be reduced upto to zero which helps us to start very large motors with full load at minimum speed and then gradually increase the speed of the motor by increasing the output ...
The cycloconverter for slow-speed synchronous and induction motors with a high torque sinamics sl150 cycloconverters with thyristor stacks are the optimum choice when it comes to continuously controlling the speed of high-rating induction and synchronous motors with a
The above features of a cycloconverter fed induction motor drive show that it provides a very smooth low speed operation with the least torque ripple. thus it is very attractive for a low speed, large power, reversible drive. this drive finds application in gearless cement mill, or ball mill drives.
A number of practical applications of these drives, include rolling mill drive with voltage-fed converters, icebreaker ship propulsion with cycloconverter drive, gearless cement mill drive with cycloconverter, dual mining ore-crushing drive with cycloconverter, cruise ship propulsion with load-commutated current-fed converters, and future ship ...

Sep 22, 2018 a cycloconverter converts mains frequency 50 or 60hz into a low frequency output. this output frequency is an integral fraction of the input frequency fout 1n fin where n 1, 2, 3.. a common use for this is to run very large synchronou...
Cycloconverter when the output frequency is less than the input frequency. the basic topology used for this purpose is a mid point cycloconverter topology b bridge type cycloconverter topology. some applications of cycloconverters are o cement mill drives o ship propulsion drives o rolling mill drives o scherbius drives
May 04, 2020 the cycloconverter has been traditionally used only in very high power drives, usually above one megawatt, where no other type of drive can be used. examples are cement tube mill drives above 5 mw, the 13 mw german-dutch wind tunnel fan drive, reversible rolling mill drives and ship propulsion drives.
Some other applications where cycloconverters can be used are cement mill drives, ship propulsion drives, rolling mills, and mine winders, washing machines, water pumps, and used in industries as well. if any further more queries on this topic or on the electrical and electronic projects leave the comments section below. photo credit
