摘要
三相感应电动机的起动过程较为复杂,而稳态特性曲线又无法准确描述实际情况,为了准确计算电机的起动特性,在αβ-dq-0坐标系下建立电动机的动态数学模型。充分考虑到电动机的实际负载,起动过程中转子参数的变化,分析并计算了电动机的起动特性与起动时间。计算结果表明,动态特性曲线比稳态特性曲线更符合电动机起动的实际情况,为设计满足客户需求的电机提供了准确的参考依据。
The starting process of three-phase induction motor is complex,and the steady characteristic curve can′t accurately describe the actual situation.The dynamic mathematical model of three-phase induction motor was established inαβ-dq-0 coordinate system to calculate the starting characteristic of the motor accurately.By fully considering the actual load of the motor,and change of rotor parameters during starting,the starting characteristic of the motor are analyzed,and its starting time is calculated.The calculation results show that,in comparison with the steady characteristic curve,the dynamic characteristic curve is more suitable for the practical starting characteristic,and the characteristic provides the accurate reference data for the motor satisfying the customer need.
