How to speed up the motor speed?

Other Parts Discussed in Thread: MOTORWARE, HVPMSMMTR

Now I am using this sample

C:\ti\motorware\motorware_1_01_00_14\sw\solutions\instaspin_foc\boards\hvkit_rev1p1\f28x\f2802xF\projects\ccs5\proj_lab10a

and the motor is working. Hardware is TI EVM.

I want to increase the motor speed, Now only go to 1000 rpm.

Would you please give me a hand, how to modify code for speed over 1000 rpm.

Thanks very much.

    proj_lab10A will allow you to increase the modulation to the maximum value, allowing for the maximum bus voltage to be applied to the motor.
    the only way to go any faster would be to use more voltage.

    first, what is the maximum speed of your motor? attach your user.h as well

    What speed are you commanding when you only reach 1 KRPM?

    Hi ChrisClearman,

       My motor maximum speed is 6k rpm.

       user.h please see attachment.

       8484.user.h

    I did not use GUI to control speed, this is just the default setting.

    Thanks very much.

    what is your Vbus?

    are you using the HVPMSMMTR that we sell?
    #define USER_MOTOR Estun_EMJ_04APB22

    If so, you should be able to reach maximum speed - which is 3 KRPM

    If you have a custom motor (you say it is 6 KRPM) you need to ID the motor parameters and update them in user.h
