Thermal calculation model with internal wind The heat inside the motor is mainly caused by the loss of stator and rotor, mechanical consumption and miscellaneous consumption. It is believed that the heat dissipation of the stator is mainly achieved by the stator heat conduction to the casing. The heat dissipation of the rotor is carried away by the air passage inside the rotor, and the other part is transmitted to the stator in the form of convection heat transfer through the air gap between the rotor and the stator. Then passed from the stator to the casing. The mechanical consumption and the stator end are mainly carried to the wall by the air inside the motor. Among them, the heat dissipation of the stator and the rotor plays a leading role in the temperature rise of the winding. The outer diameter and inner diameter of the stator are constant, the area of ​​the equivalent silicon steel sheet is equal to the area of ​​the original silicon steel sheet; the thickness of the equivalent insulating layer is equal to the thickness of the original insulating layer; the remaining area is the winding area, and the temperature of the entire winding area is the same, equal to the winding temperature. The heat dissipation of the stator is the heat generation (copper consumption) of the winding region and the heat generation (iron consumption) of the silicon steel sheet, and the mechanical strength. The calculation of heat dissipation is a two-dimensional heat conduction problem with an internal heat source in cylindrical coordinates. Ignoring the iron loss, it is considered that the rotor loss is all copper loss. The heat-generating area of ​​the rotor copper consumption is simplified as an endless belt (equivalent copper-consuming heat-generating area). Similarly, the rotor vent is also simplified as an endless belt (equivalent ventilation area), the air flow area and heat exchange area of ​​the endless belt are kept the same as the original venting hole, and the equivalent diameter of the annular belt heat transfer and flow resistance is maintained. The vents are the same. The area of ​​the equivalent silicon steel sheet is equal to the area of ​​the original silicon steel sheet, and the remaining area is the winding area, and the temperature of the entire winding area is the same. The calculation of heat dissipation is a two-dimensional heat conduction and convection problem in cylindrical coordinates. The conventional temperature rise calculation of wind turbines covers the temperature rise calculation of products in special operating environments such as high prototypes and offshore wind power. The temperature rise of wind turbines with heat sinks is calculated comprehensively and accurately. The rotor structure can be The permanent magnet can also be a conventional electric excitation method, and the calculation results are in good agreement with the experimental results. The calculation method of the temperature rise of the wind turbine in the form of heat dissipation ribs and the value of the empirical coefficient have fully explained its rationality through the test. The development of the temperature rise calculation software greatly improves the reliability of product development, shortens the development cycle, and passes different models. The calculation is in good agreement with the experimental results, which fully reflects the maturity and accuracy of the software. The software includes both the temperature rise calculation of the permanent magnet wind turbine and the temperature rise calculation of the electric excitation wind turbine. The software has high coverage and comprehensiveness.
