目前我正在使用x-Nucleo-IHM07M1开发板驱动一个直流无刷电机，下载的是en.X-CUBE-SPN7_v1.1.0 模板程序，发现程序最多达到36000 rpm左右然后就上不去了，不管改变PI哪个参数都不行，请问这套方波的模板程序能够达到这么高的转速吗？需要怎么调，下面是我的MC_Sixstep_param.h ：/*

STM32H7和F4做永磁同步电机FOC控制如何选型，哪个开发更好？
谁知道这个芯片怎么搜。
STM32G473VET6同时使用6个片上放大器(OPAMP)的PGA加外部偏置模式，引脚位置让差分信号走线分离，信号有无较大影响？
STM32G431 用MCSDK5.4.8 进行PMSM永磁同步电机FOC控制，转速上升到某一值（3500rpm）无法继续上升，上不去
【求问】ST无刷电机控制器-最高控制可调节转速是多少？

1.可以尝试提升输入电压，看看是否可以提高转速
2.nonimal current 是否正确
报的什么错误？
谢谢大佬解答。
输入电压提升，确实能提高一点转速，我用的电机额定6V，现在输入电压已经达到10V了，不太想继续提高，而且我用电机厂家官方配的方波驱动器，10V情况下已经可以达到90000RPM，而且不发烫，所以想试试调参，把ST的这块板子达到差不多的效果。
