ST Motor Workbench如何设置放置电角度

虽然数值可以从0到359，但唯一的实际选项是60和120度。对我来说，似乎不太可能在“错误”设置下你的电机运行得更好。

ST Motor Workbench - 放置电角度
 
你能描述一下如何设置''Placement electrical angle''。 ST Motor Workbench的默认值为300度。
 
 
我有一个8极电机，120度间隔霍尔传感器。根据我在网上找到的信息，我将此设置为60度，并且我在该设置下也获得了最大的扭矩。我把它解释为不同大厅状态之间的角度差异。
 
我问这个问题是因为''Placement electrical angle''的值可以是0到359度，我想知道什么时候改变了。
 
根据我的理解，如果使用120度间隔的霍尔传感器，则60度以外的值不应该正常工作......但是，ST Motor Workbench中的选项一定不是这种情况。
 
问候，

Although the numerical value can go from 0 to 359, the only real options are 60 and 120 degrees. To me it seems unlikely that your motor runs better with the ''wrong'' setting.

ST Motor Workbench - Placement electrical angle

Could you describe how to set ''Placement electrical angle''. The default value in ST Motor Workbench is 300 degrees.


I have an 8-pole motor with 120 degree spaced hall sensors. I have this set to 60 degrees based off information I found online and I get the most torque at that setting as well. I'm interpreting it as the angle difference between different hall states.

I ask the question because the value of ''Placement electrical angle'' can be from 0 to 359 degrees and I'd like to understand when that changes.  

From my understanding a value other than 60 degrees shouldn't work properly if using 120 degree spaced hall sensors...but that must not be the case hence the option in ST Motor Workbench.

Sagar

谢谢。是的，我想是的。我正在使用60度。它在UI中很奇怪，默认设置为300。

Thanks. Yeah I figured so. I'm using 60 degrees. Its just odd in the UI they have the default set to 300.

再见
 
 
 我试图澄清“传感器位移”和“放置电角度”之间的含义和区别。
 
 “传感器位移”与传感器之间的角度有关。这通常是60°或120°。这意味着物理上三个传感器在60°或120°的空间中移位，产生不同的信号序列。
 60°生成H1下降然后H2下降然后H3下降然后H1上升然后H2上升然后H3上升，依此类推
 120°度产生H1下降然后H2上升然后H3下降然后H1上升然后H2下降然后H3上升，依此类推
 
 “放置电角度”定义了三个传感器相对于定子的位移。因为FW需要知道与传感器的每次上升/下降相对应的角度。这不是让我说一个“绝对值”，你可以在电机的数据表中读到，因为你还必须定义一个名称（和每个角度）定子相的约定。所以我们的建议是直接在你的系统中手动计算这个参数（在固件中设置，以便从HALL传感器获得正确的角度测量）（所以在你将电机相连接到逆变器后建立定子的角度系统）。 FW用户手册中介绍了测量此参数的一些细节和步骤。

I'm trying to clarify the meaning and difference between ''Sensor displacement'' and ''Placement electrical angle''.

The ''Sensor displacement'' is related to the angle between sensors. And this is usually 60° or 120°. This mean that physically the three sensors are displaced in the space at 60° or 120° generating different sequences of signals.
60° degree generates H1 Fall then H2 Fall then H3 Fall then H1 Rise  then H2 Rise then H3 Rise and so on
120° degree generates H1 Fall then H2 Rise then H3 Fall then H1 Rise  then H2 Fall then H3 Rise and so on

The ''Placement electrical angle'' defines the displacement of the three sensors respect the stator. Because the FW need to know the angle that corresponds to each rising/falling of the sensors. This is not let's me say an ''absolute value'' that you can read in the data sheet of the motor because you have to define also a convention with the name (and angle of each) stator phases. So our suggestion is to calculate manually this parameter (to be set in the firmware to get the correct angle measurement from the HALL sensors) directly in your system (so after you have connect the motor phases to the inverter establishing the angular system of the stator). Some details and procedure to measure this parameters is explained in the FW user manual.
