using dvr8301-69m-kit for prototype project

1.  We developing a remote controller for an unmanned ground vehicle using DRV8301-69M-KIT. We want to ascertain compatibility between the embedded driver in the Kit and the power required by vehicle's brushless DC motor. The motor technical parameters are:

      Rated Power(W)             1200
      Rated Voltage(VDC)       48/60
      Rated Speed(RPM)        3750
      No load Speed(RPM)     3900
      Rated Torque(N.M)        30.5
      Rated Current(A)           ≤36/30/27
      No load Current(A)         ≤5/4/3
      Efficiency                     ≥83%
      Gear Ratio                    1:10

 

2.  If heating is a problem, are dissipators recommended? 

3.  Can TI identify the pin in assignment of the 20pin connector on the DRV8301-69M-Kit?

Thank you for you kind assistance in this matter.

    1. the kit you have is good to 60Vdc and 40A peaks, so you are probably ok. Many battery based 48V systems typically design a higher voltage range though to give some buffer, so this DRV8301 isn't typically used in true 48V systems.

    2. shouldn't be a major problem in this application if there is any sort of airflow on the board

    3. schematics are included in the controlSUITE installation
