grinding, coating, and other operations calling for fine surface finishes. Because they have no commutator, brushless DC
motors BLDC are more efficient, need less maintenance, and can operate at higher
speeds than conventional dc
motors.
High efficiency and small size are especially important for military, aircraft, and automotive applications, and for portable instruments and communications equipment. The cost of both brush-type and brushless DC
motors BLDC likely will rise because of increasing costs...
