Analog variable frequency filters require the use of variable passive components. The higher the slope of the filter, the greater the number of needed variable passive components. These elements are ...

Applications Variable frequency drives are used for two main reasons: To improve the efficiency of motor-driven equipment by matching speed to changing load requirements. To allow accurate and ...

Variable frequency drives typically control velocity or torque. In contrast, servodrives are often used to control motor position — and almost always use a position feedback device on the motor.
