Sequence Boundary The sequence boundary is an unconformity updip and a correlative conformity downdip. Where it is an unconformity, it is a surface of subaerial exposure and erosion; however, the expression of those features in an individual outcrop may or may not be obvious.
The brushless motor provides greater reliability and efficiency for its low weight and size as compared to the brushed motors. Efficiency for the brushless motor is typically between 85-90% while that of the brushed motor ranges between 75-80%.
DC DG PMG. The permanent magnet alternator is the core of a successful, fuel efficient DC Diesel Generator. Our PMG is a brushless alternator that produces a high frequency AC output. There is an inbuilt magnetic field through permanent magnets. The efficiency of the unit is over 93%. We use a proprietary design built through our engineers that reduces electric ripple and maintains efficiency through a range of rpms. The unit is bearingless which reduces wear and tear and requires no maintenance.
