All conventional VFDs are of the same basic design to use an input rectifier section to convert the AC to DC. That DC power is then stored in capacitors. In Figure 2, the output section draws from that DC power and sends pulses to the motor in a method called pulse width modulation. B...
A VFD or variable frequency drive is an electronic device used to control an AC induction motor or synchronous motor. A VFD controls the torque, speed, and direction of the motor, smoothly starting and accelerating the motor to the desired speed at a controlled acceleration rate. Deceleration is...
From the above you can see the IPM in the Inverter drive will control Voltage and Frequency over virtually any range the parameter settings in the VFD tells it to. This means when setting up an Inverter drive we can choose to run a small ‘Delta’ connected 230V motor from a 230V singl...

increasing use of variable-frequency drives (VFD’s) calls for a frequency range on the nameplate. If only one frequency appears on the nameplate, consult the manufacturer before applying the motor on a VFD. NEMA allows motor frequency variation of only plus or minus 5% for non-VFD ...
