P-NUCLEO-IHM001电机分析仪过流如何调整软件和硬件范围

问答对人有帮助，内容完整，我也想知道答案 0 你好。我正在尝试使用P-NUCLEO-IHM001学习FOC SDK。第一个测试的固件是''STM32CubeExpansion_SPN7_V1.0.0 Projects Multi Examples MotorControl Binary STM32F302R8-Nucleo X-CUBE-SPN7.bin''。它起作用了（我判断它只是看电机的旋转）。第二个测试的固件输出项目''C： Program Files STMicroelectronics FOC SDK STM32 PMSM FOC LIBv4.2 Web Project MDK-ARM UserProject STM32F30x_UserProject.uvprojx''。（使用STMCWB输出参数.c / .h文件，3个分流和6极对）串行通信似乎很成功，但按下[Start]按钮后1秒内出现过流故障。我听说PWM声音会逐渐变大。（请查看附加的截图图片......）在停止电机轮廓仪之前，稳定电源指示0.05A。所以我想知道3个问题。 1.How Motor Profiler如何判断第一序列的电流。 * STMCWB设置为默认值（标称值为2.1A）。 2.如何调整（软件/硬件）该范围。 3.为什么X-CUBE-SPN7.bin起作用了。 [电机规格] http://www.hobbyking.com/hobbyking/store/__42861__Turnigy_Aerodrive_DST_700_Brushless_Outrunner_motor_700kv.html 请原谅我糟糕的英语。最好的祝福。＃p-nucleo-ihm001＃foc-sdk＃dst700 以上来自于谷歌翻译以下为原文 Hi there. I'm trying to learn FOC SDK using P-NUCLEO-IHM001. First test's firmware is ''STM32CubeExpansion_SPN7_V1.0.0ProjectsMultiExamplesMotorControlBinarySTM32F302R8-NucleoX-CUBE-SPN7.bin''. It worked(I judged it only just looking rotation of motor). Second test's firmware is output of project ''C:Program FilesSTMicroelectronicsFOC SDKSTM32 PMSM FOC LIBv4.2WebProjectMDK-ARMUserProjectSTM32F30x_UserProject.uvprojx''. (Using STMCWB outputs parameter.c/.h files, 3 shunt & 6 pole pair) It seems success about serial communication, However Over-Current faults occurs in a 1 seconds after push the [Start] button. I heard PWM sound would gradually get bigger. (Please check appended screenshot image...) Stabilized power supply indicated 0.05A, just before stop motor profiler. So I want to know 3 matters. 1.How Motor Profiler judge current of first sequence. *STMCWB setting was default(nominal 2.1A). 2.How can I tune(software/hardware) that range. 3.Why X-CUBE-SPN7.bin was work.

答案对人有帮助，有参考价值 0 再见您目前的选项是降低设置到电机部分的标称电流。 2.1A是硬件过流保护，如果您将此值设置为标称电流，您将确保过流错误。标称电流必须低于那个，不仅低于，而且低于此值，因为由于PWM的产生，电流中存在一些纹波，这取决于所施加的总线电压，主要取决于电机的电感。例如，如果在MC-Kit中编程的默认FW情况下具有工作条件，则使用0.7A的额定电流。您可以尝试找到正确的值。为了高，您将得到过电流，低电流，并且您无法获得足够的扭矩来旋转电机。再见梁咏琪以上来自于谷歌翻译以下为原文 Ciao The option that you have at the moment is to decrease the nominal current set into the motor section. The 2.1A is an hardware over current protection, if you set this value as nominal current you will have for sure the over current error. The nominal current must be below that one and not only below but greatly below, this because there are some ripple in the current due the PWM generation that depends on the Bus voltage applied and mostly from the inductance of the motor. For instance to have a working condition in case of the default FW programmed in the MC-Kit we used 0.7A of nominal current. You can experiment to find the proper value. To high and you will get overcurrent, to low and you can not have sufficient torque to spin the motor. Ciao Gigi
