Nov 24, 2013· 2 There are basically 2 types of vector drives: closed-loop, and open-loop or sensorless 3 Closed-loop vector drives require special motors with encoder feedback (hence the term "closed-loop") that provide motor shaft position info to the drive The drive uses this information to constantly alter the V/Hz ratio to produce maximum torque

Most modern closed-loop CNC systems are able to provide very close resolution of 00001 of an inch Closed-looped systems would, naturally, require more control devices and circuitry in order for them to implement both position and velocity control This, obviously, makes them more complex and more expensive than the open-loop system

Closed-circuit systems The efficiency of the early stages of grinding in a ball mill is much greater than that for formation of ultra-fine particles, so ball mills operate most efficiently by making a coarse product, the fine fractions of this then being separated, and the coarse part being returned to the mill inlet
