BOOSTXL-DRV8305EVM电机参数识别电机不转

我使用的是基于BOOSTXL-DRV8305EVM和TMS320F28027板子,电机最大电流25A,Kv2000,在使用lab02c时,电机总是在RampUp阶段不转动。

 

按照User Guide里说的,逐渐加大USER_MOTOR_RES_EST_CURRENT,到达2A以上时,板子上的nFault指示灯就会亮起;

 

然后识别的参数误差会很大,电机也不转动;

 

当我仅使用航模所用的电调,输入PWM信号时,电机可以转动,电流达到1.2A左右,但是使用识别电路板,电流到达1.1A左右或者以上时,nFault灯常亮;

 

想问一下,怎么查找nFault灯亮的故障码?在程序里哪个变量里可以看到?

 

其次,怎么继续增大USER_MOTOR_RES_EST_CURRENT,nFault指示灯才不会亮,并且电机能够转动,完成电机识别过程呢?

 

 

 

以下是我的user.h文件 内容:

Susan Yang:

1.请设置正确的增益,并在user.h中设置相应的USER_ADC_FULL_SCALE_CURRENT_A和USER_ADC_FULL_SCALE_VOLTAGE_V。
2.根据您的电动机设置正确的USER_MOTOR_RES_EST_CURRENT,USER_MOTOR_IND_EST_CURRENT和USER_MOTOR_FLUX_EST_FREQ_Hz。

另外对于电机识别,电机需要在空载或轻载下工作,尤其是对于Ls和磁通量识别

回复 Susan Yang:

我确定我所设置的USER_ADC_FULL_SCALE_CURRENT_A和USER_ADC_FULL_SCALE_VOLTAGE_V均根据硬件设置正确,且USER_MOTOR_RES_EST_CURRENT,USER_MOTOR_IND_EST_CURRENT和USER_MOTOR_FLUX_EST_FREQ_Hz的设置也按照手册设置,区别在于我所使用的电机是不得不带负载的油泵电机,按照使用手册需要更大的USER_MOTOR_RES_EST_CURRENT,但是我将此数值增大到2A以上时,电机仍然不转动,且在RampUp阶段,板子的nFault指示灯常亮。

我联系了设计电路板的人员,基本排除硬件的限流原因,现在想知道在软件中,是否有对估算电流的限幅?如果有的话,在哪里可以更改呢?

Susan Yang:

回复 Alex He:

根据手册说明

另外请参考E2E上相关帖子

Alex He:

回复 Susan Yang:

我从1.0A开始设置,以0.1为增量逐渐增加,当电流达到2.0A时,电机依然没有转动,继续增大该值,就会出现板上nFault指示灯常亮,识别过程还在继续,但是电机不转,识别出的参数数值很小,严重偏离实际值。

回复 Alex He:

谢谢您的反馈,我们会在研究确认后给您回复。

Susan Yang:

回复 Alex He:

看起来是未正确识别电动机。请在电动机上不加任何负载进行识别,并根据电动机的规格在user.h文件中设置正确的识别变量值,以确保在磁通量测量和Ls识别状态下电动机平稳旋转。

#define USER_MOTOR_RES_EST_CURRENT(1.0)// A - 10-30% of rated current of the motor#define USER_MOTOR_IND_EST_CURRENT(-1.0)// A - 10-30% of rated current of the motor, just enough to enable rotation#define USER_MOTOR_MAX_CURRENT(5.0)// A - 30~150% of rated current of the motor#define USER_MOTOR_FLUX_EST_FREQ_Hz(20.0)// Hz - 10~30% rated frequency of the motor

Alex He:

回复 Susan Yang:

我的电机需要带动油泵才能够正常运转,不得不带负载运行;

根据所给定的数据,以及我自己调试的数据来看,电机无论在哪个参数下都无法平稳旋转;因为电机根本就没有在旋转;根据使用手册,我应该增大

#define USER_MOTOR_RES_EST_CURRENT(1.0)// A - 10-30% of rated current of the motor但是,增大该变量到2A,电路板上报错,就无法再驱动电机了。
