Fastened-pace, traditionally, SCIM the world's workhorse particularly in low-performance functions of every type Variable-pace, historically, low-performance variable-torque pumps, fans, blowers and compressors. Variable-speed, more and more, different excessive-efficiency fixed-torque and constant-power or dynamic masses. Fastened-speed, low-efficiency functions of all kinds. Variable-velocity, historically, WRIM drives or fastened-velocity V/Hz-managed VSDs. Variable-velocity, more and more, v...
