[TowerTalk] What Rotors Run on DC? Swap for One?

[K0FF]

Main advantages to DC motor is that the speed can be adjusted easily. The
new Orion 2800DC uses this feature to ramp the motor up and down on
start/stop. Great idea for heavy/long loads.
Principal disadvantage is that the motors generally require brushes, which
can wear
 ( carbon dust is messy too). Motor design can be either Permanent Magnet
type, or field winding type.

Main advantage to AC motors is simplicity of control circuit design, and
easy design of relay-boosters for very long runs.
