Mfundo yogwiritsira ntchito valve yamagetsi yamagetsi awiri ndi yakuti dalaivala amayendetsedwa ndi motor reversible synchronous motor yokhala ndi maginito clutch. Pogwiritsa ntchito mphamvu ya maginito ya injini kudzera mu rotor yamoto ndi clutch, torsion yokhazikika imatha kupangidwa pamene galimotoyo ili pamalo oima. Chifukwa chake, injiniyo ikakhala ndi zida zapano, imatha kuyima nthawi iliyonse mokhazikika. Vavu ikatsegulidwa kapena kutsekedwa kwathunthu, maginito clutch amalekanitsidwa ndipo kusinthako kumayimitsidwa. Chizindikiro chochokera kwa dalaivala wowonjezera kapena wowongolera amatha kupangitsa injiniyo kutembenuka molunjika kapena motsutsa.
