器件型号：MCT8329EVM
主题中讨论的其他器件： MCT8329A

我们使用 MCT8329EVM 驱动电动自行车 BLDC 电机。

电机规格为：36V、最大580W。无负载。

我们尝试通过对齐、双对齐、IPD 和慢优先来启动电机。

只有先慢才可以正常工作。所有其他方法都将失败。

但是、我们可以按如下方式来转换参数并设置各种占空比：

问题：

1.有时启动过程可能会失败。

2. 0x417似乎是负值，如果占空比>40%则保持0x8000000

3.如果我们将启动频率设置为小于40Hz，则会发生短路。

4. 0xEC 电流始终为0xFFFF、电池电源值错误

之后、我们尝试其他参数、如下表所示：

尊敬的 Realman：

当您发现启动故障时、nFAULT 引脚是否变为低电平、您能否描述电机在故障发生时会发生什么情况？
当占空比为50%时、测得的电流和电压值是多少？
您能告诉我、启动频率小于40Hz 时、短路发生在何处吗？
如果将 MCT8329A 芯片更换为已知良好的芯片、这些问题是否仍然会出现？

此致、

约书亚

你好、Joshua、

感谢您的回答。

1. 1~2使用 IPD 启动、电机会抖动 μ s、然后0xE2报告0xA0000000：IPD 频率故障。
我们将 IPD_CLK_FREQ 从50Hz 更改为2000Hz。
都无法正常工作。

2. I：~μ A 506mA、V：40.8V

3.将电动自行车电池电源连接到8329 EVM。
当电机发生故障时、它会触发电池上的短路 PROTECT 信号。
电池会立即切断电源。

4.我们已经把 MCT8329安装到了 EVB 上、情况是一样的。

还有一点：
在慢速优先模式下：
答：我们可以从0%到10%~100%阶跃10%的范围内启动、它们几乎成功。
但是、我们以10%运行、然后速度达到80%、90%或100%、它会立即发生短路。
以20%运行、速度高达90%、100%：短路
以30%或以上的速度运行、可任意占空比：安全

B.我们发现减速非常慢。但是、当我设置 FAST_DECEL_EN=1时、减速非常快、但会立即短路。

下面是 DUTY=0%时的参数

尊敬的 Realman：

Unknown 说：
我们尝试使用 IPD 启动，电机抖动1~2 μ s，然后0xE2报告0xA0000000：IPD 频率故障。

请尝试与 IPD 频率一起调整 IPD 电流限制。如果电机电感对于 IPD 电流限制或频率而言过高、或者 IPD 频率对于电流限制而言过高、这可能会导致 IPD 频率故障。如需更多信息、请参阅数据表的第7.3.20.12节。

4. 0xEC Current 始终为0xFFFF、电池电源的值错误[/报价]
Unknown 说：
2. 0x417似乎是负值、如果 duty >40%
、它将保持0x80000000
我假设您要引用寄存器0x714？请参阅此帖子中的最新建议： https://e2e.ti.com/support/motor-drivers-group/motor-drivers/f/motor-drivers-forum/1276831/mct8329evm-why-are-the-values-of-current-and-power-weird。

Unknown 说：
我们发现减速非常慢。

如果 CL_DEC_CONIF 设置为0b、则要增加减速度、请增加 CL_DEC 值、否则闭环减速率由 CL_ACC 中的值确定。

对于您看到的短路问题、请尝试通过调整 DIG_DEAD_TIME 寄存器来增加死区时间插入。如需更多信息、请参阅数据表的第7.3.2.1节。

如果这无法帮助您捕获 GHx、GLx 和 SHx、然后查看是否发生直通。

此致、
