Type CVR armatures feature five segments instead of the normal three. A five-segment armature will provide extremely good low speed control, but will sacrifice power, torque and drag brake. Typically half the winds of three-segment armature will result in the five-segment equivilant. EX: 35 Turn, three-segment = Approx. 17 Turn five-segment.
