Variable Torque

A variable torque VFD (Variable Frequency Drive) is designed for applications where torque demand decreases as speed decreases. These drives are optimized for energy efficiency in systems like centrifugal pumps and fans, where power requirements drop dramatically at lower speeds.

Key Characteristics of Variable Torque VFDs:

• Torque decreases with the square of the speed.

• Power (HP) decreases with the cube of the speed.

• Lower current demand compared to constant torque drives at reduced speeds.

• Often includes energy-saving features.

• Typically not suitable for applications that need full torque at low speeds.
