Abstract
Established functional relationships and formulas for calculating the full energy of synchronous electromagnetic stirrers, combining synchronous electric machine and a rotating magnetic system of permanent magnets. Grounded requirements to ensure stable operation of the synchronous stirrer and eliminate its possible falling out of synchronism. The requirements for the magnitude of the stator current and the magnitude of the magnetization of the permanent magnets of the excitation system, which is also used to provide liquid metal in the magnetic induction of a given value. It is shown that under the same designs of the magnetic induction field system in the liquid metal can create higher value for underexcited operation mode of a synchronous machine. Modes control stirrer and the magnitude of the magnetic induction in the liquid metal it is expedient to change the voltage of the stator winding. References 8, table 1, figures 4.
