The article presents data that during the operation of synchronous motors at metallurgical enterprises, they give reactive power to the electrical network when switching to overexcitation mode, which, as a result, contributes to an increase in the value of cosjн in the part of the network connected to the load. For this reason, a method for designing synchronous motors for operation at rated power during overexcitation and in the case of cosjn=0.9 is considered, which creates the possibility of energy saving.
