西门子只是提供电机部分参数,内部参数不公开提供。但可以变通一下得到。
在starter中选择对应的电机,参数中就会调出与控制有关的相应的数据。
如楼主这个电机,相关参数如下:
Parameters(304, 0) = 385.255 'Rated motor voltage
Parameters(305, 0) = 1.43875 'Rated motor current
Parameters(307, 0) = 0.55 'Rated motor power
Parameters(308, 0) = 0.635412 'Rated motor power factor
Parameters(310, 0) = 50 'Rated motor frequency
Parameters(311, 0) = 1500 'Rated motor speed
Parameters(318, 0) = 2.2 'Motor stall current
Parameters(320, 0) = 0.860035 'Motor rated magnetizing current/short-circuit current
Parameters(322, 0) = 3200 'Maximum motor speed
Parameters(329, 0) = 0.071458 'Motor pole position identification current
Parameters(340, 0) = 1 'Automatic calculation motor/control parameters
Parameters(341, 0) = 0.002 'Motor moment of inertia
Parameters(344, 0) = 12 'Motor weight (for the thermal motor model)
Parameters(350, 0) = 9.7391 'Motor stator resistance cold
Parameters(356, 0) = 169.947 'Motor stator leakage inductance
Parameters(357, 0) = 757.758 'Motor stator inductance d axis
