i got a set of bldc demo as below:

?TWR elevator

?TWR K60D100M


?TWR serial


the motor can run when i config it as bldc with sensors .when i config it as sensorless ,it just vibrates in stead of running ,the motor got hot after sometime of vibrates.


i configged the jumps on the TWR MC-LV-3PH  and download the software of "BLDC_Sensorless_Kinetis_rev_B.exe".
