Variable Frequency Drives (VFD’s)
Constant Torque Loads •Horsepower increases or decreases as a direct function of speed. – A 50% drop in speed produces a 50% reduction in power required to turn the load. •Energy savings using a VFD to control the speed of a constant torque load is a direct function of speed reduction. Variable Torque Loads • Require much lower torque &

DC Braking A function that applies a DC voltage to the induction motor for braking control (i.e., firmly stops motor rotation). The function operates either when the motor starts or stops.

By function it is a “constant-airflow motor.” Both of these terms define the type or style of ECM and how it is programmed to function. Variable-speed motors are built in 1⁄ 3-, 1⁄ 2-, 3⁄ 4-,
