Other Parts Discussed in Thread: MOTORWARE
Invertor : DRV8301-69M kit based invertor with proper thermal/ heat sink design
MCU : F28069M controller
Software : Motorware / Torque control
We have customer requirement to use gearless sine wave motor. Since there are no gears it requires huge torque/ current at startup.
Currently we are limiting the current to 40A max, since as per datasheets (DRV-8301-69M Kit) the max current is 40A.
When the motor is moved very slightly under load conditions it works properly. But without that movement it fails start on its own.
As per motor specs the motor needs around 70A surge current at startup (from standstill).
My question is can i supply surge current (more than 40A) for few seconds (say 5secs) during startup. As of now I am programing the timer to 5secs and later removing the surge/ boost current. But limited the current to 40A.
Many Thanks and Regards
