WebSep 17, 2014 · Adding a variable-frequency drive (VFD) upstream of an AC motor can lower energy use, reduce peak demand and improve power factor in many applications. Reducing motor speed at startup and during operation can cut maintenance costs, increase uptime and extend equipment life.

WebMar 8, 2024 · An easy experiment, if it is a brush-type motor, is to try running it on 12 volts DC. You can try that first off a car battery, and if the speed is OK then one of those 12 volt or 19 volt power supplies from a resale shop can drive it and you are all set. That is about the cheapest way and it may have enough torque for your application. WebUnlike DC motors, an AC motor's speed cannot be controlled by modifying the input voltage. Instead, it is necessary to change the AC power supply frequency, which determines the speed of the rotating electromagnetic field in the motor that turns the rotor shaft. A VFD (or Variable Frequency Drive) achieves this by converting the AC power to DC.

WebIn order to maintain torque at a speed other than its rated speed, you need to adjust the frequency in proportion to the voltage. If you want to do it right, you rectify the AC into a DC bus and then use IGBTs to chop up the bus (using PWM) to generate an AC waveform at the frequency and average voltage you need.
