Part Number: LAUNCHXL-F28069M
Other Parts Discussed in Thread: BOOSTXL-DRV8305EVM, MOTORWARE

LAUNCHXL-F28069M+BOOSTXL-DRV8305EVM使用Lab02b运行,电机不动作。电机参数,24V,0.5A,扭矩0.005Nm,2000RPM。JP6短接,JP7断开,JP4,JP5断开;

  • Hi,

    我已经向相关工程师寻求帮助了,有了结果我会第一时间回复。

  • Hi,

    请查看motorWare中以下文件夹中的指南,并按照指南设置套件和运行Lab:

    C:\ti\motorware\motorware_1_01_00_18\docs\labs\instaspin_labs.pdf

    C:\ti\motorware\motorware_1_01_00_18\docs\boards\kits\docs\readmefirst_instaspin_launchboost.pdf

    当您使用lab02a/b/c时,在辨识的过程中请不要给电机加任何负载,并在user.h中根据电机的规格设置正确的辨识参数值,以确保电机在Flux测量和Ls辨识状态下平稳旋转。

    #define USER_MOTOR_RES_EST_CURRENT     (2.0)                               // A - 10-30% of rated current of the motor

    #define USER_MOTOR_IND_EST_CURRENT     (-1.5)                             // A - 10-30% of rated current of the motor, just enough to enable rotation

    #define USER_MOTOR_MAX_CURRENT           (20.0)                               // A - 30~150% of rated current of the motor

    #define USER_MOTOR_FLUX_EST_FREQ_Hz     (40.0)                           // Hz - 10~30% rated frequency of the motor

    请详细描述您的问题,操作步骤和测量的电流波形将有助于我们了解您的问题。
