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%.
Cam Lobe Motor - A hydraulic radial piston motor in which rotational force is created by the outward movement of the pistons against the lobes of a stationary cam. Cavitation - A phenomenon which occurs when the pressure at a point in a hydraulic system is lowered below the vapor pressure of the oil in the system. This allows bubbles of oil vapor to form in the oil.
