Description
Summary:The paper presents original modified thermal networks for calculations of the temperature field in induction mine motors under steady and transient conditions aiding design and setting thermal protections. They can be used for location of the hottest places in motor elements in order to place in them sensors for temperature measurements. They can be also applied to determining the equivalent thermal constants of windings needed when setting microprocessor thermal protections.
