L6235换向方案线圈的电流被切断

问答对人有帮助，内容完整，我也想知道答案 0 我们遇到了特定电机的问题：通过标准连接，一个旋转方向具有显着的低扭矩，并且在两个特定的霍尔传感器状态下，线圈的电流被切断！改变电动机线圈和霍尔传感器的连接（OUT1->线圈2，OUT2->线圈3，OUT3->线圈1和大厅连接相同）解决了这个问题。这是什么原因？数据表中没有提示，应用说明中没有提示。此外，当我试图与ST接触时，我失败了。 ST似乎拥有“我们的产品，您的问题”这一理念。无论是通过经销商还是在德国ST总部的绝望电话，都无法与FAE取得联系。我非常后悔使用ST的产品，因为如果有一个（甚至是严重的）问题，我一个人就不用了！＃L6235 以上来自于谷歌翻译以下为原文 We got a problem with a specific motor: With the standard connection one direction of rotation has a significant lower torque and also at 2 specific hall sensor states the current to the coil is switched off ! Changing the connection of the motor coils and Hall sensors ( OUT1-> coil2, OUT2->coil3, OUT3-> coil1 and the hall connections the same) cures the problem. What is the reason for that ? There is no hint in the data sheet, no hint in an application note. Also when i tried to get in contact with ST i failed. ST seems to have the philosophy 'our products, your problem' To get in contact with a FAE is impossible whether trying via distributors or even with a desperate call to ST headquarter here in Germany. I regret very much to use a Product from ST because if there is an (even serious) problem one ist left alone! #l6235 0

答案对人有帮助，有参考价值 0 对于您在我们的客户支持方面的糟糕体验，我深感抱歉。当然，这不是我们想要给客户的信息。回到你的问题。你能分享一下电机的数据表和一些关于你用其他配置获得的异常行为的波形吗？（OUT1-coil1，OUT2-coil2，OUT3-coil3和霍尔传感器相同，我猜）。以上来自于谷歌翻译以下为原文 I'm sorry for your bad experience with our customer support. For sure this is not the message we want to give to our customer. Going back to your issue. Could you share the datasheet of the motor and some waveform about the anomalous behavior you obtain with the other configuration? (OUT1-coil1, OUT2-coil2, OUT3-coil3 and the same for the hall sensors, I guess).

答案对人有帮助，有参考价值 0 ，，恩里科你好，很高兴与ST的真人接触。我们使用的是Maxon的EC13电机（430155）。我们还尝试了Maxon不同的其他电机，它们都在工作。以正常方案（OUT1-coil1，OUT2-coil2，OUT3-coil3）连接EC13电机，一个旋转方向正常工作，另一个方向是线圈电流始终处于霍尔状态H1 = L H2 = L H3 = H.这将使电机以低速停止。因此，更改电机与OUT1-coil2，OUT2-coil3，OUT3-coil1和霍尔传感器的连接可以解决问题。改变与OUT1-coil3，OUT2-coil1，OUT3-coil2的连接问题返回，但电机将在霍尔状态H1 = L，H2 = H，H3 = L时停止。在运动期间用示波器观察霍尔信号，显示出预期的模式，只是添加了一些噪声。我们得到了评估板L6235N以及我们自己的L6235PD板的问题。我还买了一个L6229的评估板，这个IC工作没有问题!!!! 你能解释一下L6235的行为吗？为什么线圈的电流没有在DIAG引脚上显示任何东西而关闭？最好的祝福 GeorgSpÃ¶rl t +49（0）7225 684 - 523 f +49（0）7225 684 - 900 e G.Spoerl@precitec.de< ;,mailto：G.Spoerl@precitec.de>，我www.precitec.de＆lt;，http：//www.precitec.de>， Precitec GmbH＆amp;，Co。KG DraisstraÃŸe1 76571嘉格纳德国 Amtsgericht Mannheim，HRA 521141 KomplementÃ¤rGmbH/无限责任合伙人：Precitec Consulting GmbH，65760 Eschborn，Amtsgericht Frankfurt / M，HRB 75364 GeschÃ¤ftsfÃ¼hrung/董事会成员：Benno Stork博士。 Wer*org，Thilo Stork博士。 Werorg，Michael Bauer博士，Stephan Biermann博士 *********************************************** ********************************************** ********************************** 该通信是在尽职调查的情况下编制的，但是信息（例如技术数据，交货时间和价格）按“原样”提供。 Precitec无法保证完整性，准确性或可靠性。此消息可能包含机密和/或特权信息。如果您不是收件人或有权为收件人收到此信息，则您不得根据此信息或此处的任何信息使用，复制，披露或采取任何行动。如果您错误地收到了此消息，请立即通过回复电子邮件通知发件人并删除此消息。谢谢您的合作 ********************************************** ********************************************** ********************************** 冯：恩里科波利 Gesendet：Mittwoch，1。Februar 2017 14:33 An：Spoerl Georg Betreff：Re： - Re：L6235换向计划 STMicroelectronics Community＆lt ;,https：//community.st.com/？et = watches.email.thread＆gt;，回复：L6235换向方案电源管理和电机控制中的Enrico Poli＆lt;，https：//community.st.com/people/Poli.Enrico？et = watches.email.thread＆gt;的回复 - 查看完整的讨论＆lt;，https：//社区。 st.com/message/145175-re-l6235-commutation-scheme?commentID=145175&,et=watches.email.thread♯comment-45175>, 以上来自于谷歌翻译以下为原文 , , Hello Enrico, very nice to get in contact with a real person at ST. We are using an EC13 Motor from Maxon (430155). We also tried out different other motors from Maxon, they are all working. Connecting the EC13 motor in the normal scheme (OUT1-coil1, OUT2-coil2, OUT3-coil3 ) one direction of rotation is working as expected, the other direction the current to the coil is switched off always at the Hall state H1 =L H2=L H3=H. This will stop the motor at slow speed. Changing the connection of the motor to OUT1-coil2, OUT2-coil3, OUT3-coil1 and the hall sensors accordingly will cure the problem. Changing the connection to OUT1-coil3, OUT2-coil1, OUT3-coil2 the problem returns but the motor will stop with at the hall state H1=L, H2=H, H3=L. Looking at the hall signals with an oscilloscope during motion shows a pattern as expected just added with some noise. We got the problem with the eval board L6235N and also with our own board with the L6235PD. I bought also an eval board of the L6229 and this IC works without problems!!!! Can you explain the behavior of the L6235 ? Why is the current to the coil switched off without showing anything on the DIAG Pin ?
