Controlling Induction Motor Speed with Fixed Frequency Supply

Click For Summary
Induction motors connected to a fixed frequency supply operate as constant speed drives. To control the speed of these motors, options include using a variable frequency drive (VFD) or altering the number of poles in the motor. VFDs adjust the frequency of the supply, allowing for precise speed control. Changing the number of poles can also modify the motor's speed characteristics. Effective speed control is essential for optimizing motor performance in various applications.

If I have an induction motor connected to a fixed frequency supply then it is essentially a constand speed drive.

How can I control the speed of such a machine?

Thread 'I thought it was only Amazon that sold unsafe junk'

I grabbed an under cabinet LED light today at a big box store. Nothing special. 18 inches in length and made to plug several lights together. Here is a pic of the power cord: The drawing on the box led me to believe that it would accept a standard IEC cord which surprised me. But it's a variation of it. I didn't try it, but I would assume you could plug a standard IEC cord into this and have a double male cord AKA suicide cord. And to boot, it's likely going to reverse the hot and...
