Based on your hall sensor displacement you should be getting a waveform similar to above when the motor is running. 

All the 3 hall sensor signals shall not be all low or high, then there is a problem. Tap the 3 hall sensor signals and check on oscilloscope.

Do you use sensored (hall based) commutation? 

H1,H2,H3 are hall signals

U,V,W are the inverter outputs. Both are different.
