AVariable Frequency Drive (VFD)is a type of motor controller that drives an electric motor by varying the frequency and voltage supplied to the electric motor. Other names for a VFD arevariable speed drive,adjustable speed drive,adjustable frequency drive,AC drive,microdrive, andinverter. Frequency...

The continuing trend towards more efficient energy consumption in motor drives has led to a wide offering of devices for the power stage of variable speed drives. An integrated solution like the new SmartDriver provides a highly flexible method to contro
Variable frequency drives are one place where EMI can cause problems, and chokes on the motor phase outputs are generally prescribed. He used an expensive choke marketed as specific for VFD applications on one of his machines, but wondered if a cheap ferrite core would do the job just as ...

The pressure sensor in the duct will send a signal to theVariable Frequency Drive(VFD) causing the supply and return fans to slow down or reduce its RPM. If the pressure in the duct decreases because the VAV boxes are opening due to the need for additional cooling, the pressure sensor wil...
Cable Shielding: Using shielded motor cables can help reduce electromagnetic interference and protect the motor from high-frequency voltage pulses. For reference, the formula for the reflection coefficient is below. The greater the mismatch, the greater the voltage amplification factor. ...
