电机软启动器启动时间的计算

Calculation of Starting Time of Motor Soft Starter

以电机软启动器时间计算研究为主,通过对电启动机在从最开始的运转到运行结束每个阶段的运动速度以及运动时间、力矩等,计算出电机在每段时间内加速运行的时间。结果证明在知道一端电压、电机力矩、负载力度的情况下,能够得到电机在运转过程中的平均电压,然后在通过电压与加速力矩,得到电机在某一时间内的运行速度,将这些运行速度相加,直到电机的运动结束为止,得到电机在整个启动过程中的时间。通过这些计算,我们可以知道,电机软启动器时间计算所涉及的内容很多,电厂中软启动器时间计算的精确度要求是相当高的。

with the motor soft starter time calculation research,through to the electric machine to start in from the start of the run to the end of run for each stage of the movement velocity and movement time,torque motor is calculated in each period of time acceleration operation time.The results proved that know the end voltage,torque motor,load strength condition,can get the motor in the operation process of the average voltage,and then through the voltage and acceleration torque motor,can be in a time of running speed,the speed of movement of the motor phase,until the end,to receive the motor in the whole process for starting time.Through these calculations we can know,motor soft start time calculation involves many contents,plant soft starter time calculating accuracy is quite high.
