Throttling the output, lowers the motor current but heating may occur due to reduced air flow. Max. Thread Starter spike1947 Joined Feb 4, 2016 484 Jun 27, 2024 #8 MaxHeadRoom said: 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.

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.

WebAn AC motor is effectively a dead short when connected to DC, and it's almost a dead short when the frequency is very low. The motor might work beautifully at 120V and 60Hz, but it will immediately burn up at 120V and 10Hz. The frequency change is what slows the motor down, and the voltage drop is what prevents the motor from burning up at that ...
