Variable Frequency Drive Theory
VFD Theory: 43. Constant Torque vs Variable Torque. • Variable Torque (VT) refers to centrifugal pump and fan applications. Their load torque “varies” in proportion to the square of motor speed. • Constant Torque (CT) refers to most other applications. Their load torque is based on friction losses which are relatively.
