ELECTRONIC REGULATOR FOR ECONOMICALLY SUPLYING MACHINES EQUIPPED WITH ASYNCHRONOUS ELECTROMOTORS WITH STAR-TRIANGLE START-UP

摘要

the invention relates to an electronic controller.which provide the asynchronous connection electromotoarelor on star if power consumed is below about 40% of nominal power of electromotorului known as this characteristic pierelectrical derile are smaller and better power factor. the regulator device is completed and the idling timed and protection to overload.the regulator according to the invention works on the basis of calculation through a circuit realized with analog electronic components with static functions with the possibility of tracking on a beach on li limitit's procesuluicondus wide values of maximum and minimum loading respectively. the device can be applied to all cars tools with star triangle starting converters and to weld.
