Abstract

Heat conditions on components even on systems will impress a lifetime of components and affect all systems. On BLDC motor system with power capacitance of 120 kW will simulate the 3dimension (3D) model as divided into 2 components which are BLDC Motor 120 kW and Infineon IGBT type FF1400R12IP4. The simulation does in full power situation. BLDC Motor 120 kW model using 1 slot on stator with water cooling and 1 pole magnet on rotor. The stator winding will become heat source, with maximal power value is 1/9 of power rate, while IGBT model uses 3 pcs of IGBT arranged in cooling plate. Each IGBT will become a heat source with maximal input power to system being 40 kW. Simulation time run is t=3600s. The simulation base on online simulation using SimScale, generated the thermal change on each supporting component of the system. Final condition after 3 situation simulation sequentially of BLDC Motor and IGBT will generate final temperature on face133, face193, face177 and face185 of stator winding is 442.68°K, 439.75°K, 430.6°K and 424.59°K On face1602, face5562 and face84 of IGBT is 854.21°K, 663.74°K and 635. 78°K.

120kW无刷直流电机集成控制器的传热模型

部件甚至系统上的热条件都会影响部件的使用寿命并影响所有系统。对功率电容为120kw的无刷直流电机系统进行三维(3D)模型仿真，将其分为120kw无刷直流电机和英飞凌IGBT型FF1400R12IP4两部分。仿真在全功率情况下进行。无刷直流电动机120kw型号，采用1槽定子水冷，1极磁铁转子。定子绕组将成为热源，最大功率值为功率率的1/9，而IGBT型号使用3个IGBT放置在冷却板上。每个IGBT将成为一个热源，系统的最大输入功率为40千瓦。模拟时间运行t=3600秒。仿真基于SimScale在线仿真，生成了系统各支撑部件的热变化。无刷直流电机和IGBT依次进行3种情况模拟后的最终状态，定子绕组face133、face193、face177和face185的最终温度分别为442.68、439.75、430.6和424.59°K。IGBT的face1602、face5562和face84的最终温度分别为854.21、663.74和635°K。78°K。
