What is an Inverter Drive?
An Inverter drive (also known as AC Drive, Variable Frequency Drive, or VFD) is a motor drive device which regulates the amount of power supplied to a motor, allowing for precise control of speed or torque to the motor to suit its application. They are situated between an electrical supply and a motor. Electrical motors run many things we use in our society today and AC drives are used for speed control in a range of applications, such as simple fan and pump loads. These units are also used widely in industrial applications for high torque machine control. Most now have features such as digital operation and LED displays allowing for easy set-up, monitoring, and adjustment of parameters by the user.
How does an Inverter Drive work?
Inverter drives are controlled by inputting specific frequencies or parameters into the device. When power goes through the drive the inverter adjusts the frequency and voltage that is supplied to the motor. They ensure that an electrical motor receives only the necessary amount of power it requires to function, in order to reduce waste or loss of electrical energy, thereby making it more efficient to run. They can also gradually ramp up power for a slower, safer machine start up. Inside the inverter, incoming AC power is converted to DC power via a rectifier made up of diodes, which is then smoothed to a clean, constant voltage by capacitors, and is then fed back out as AC power via output transistors.

Great Book.
Format: Mass Market Paperback
Its great to be able to go back and read Stokely Carmichael today in his own words. This book provides an excellent overview of what black power means and how the concept originated. Although the book seems a bit dated today, many of the ideas presented are still entirely relevant.
Ive only given the book four stars due to its age. Many of the statistics presented are dated, and undoubtedly there are other texts available today that present these ideas in a much better/newer way. But if you are interested in Stokely Carmichael and what he stood for, this is the book to read.

Format: Paperback
Excellent articulation of the Black Power initiative within the Civil Rights Movement. A detailed view of Black Power, it's objectives, how these would be achieved, as well as it's misinterpretations.
An afterword from each author appended in 1992 provides insight, reflection, and perspective on all that's changed, and what hasn't, since the book's publishing.

Get one while you can
Format: Mass Market Paperback
Any book with the name Stokely Carmichael is a rare find. You can easily find the same book with Kwame Ture as the author since he changed his name and so later editions reflects the name change. Kwame Ture (fka Stokely Carmichael) changed his name for a reason. However, those of us from the sixties can never forget him nor the name Stokely Carmichael.
