Electrical Motor Control Systems (Book with DVD)

Once the proper motor is selected, understanding the many various control devices available and their uses and limitations becomes an important part related to reliable operation and protection of the motor and the personnel using the motor. An understanding of each of these areas is necessary to e ectively apply motor control principles and equipment to e ectively operate and protect a motor. Motor controllers can be manually, remotely or automatically operated. They may include only the means for starting and stopping the motor or they may include other functions. This book discusses the basic concepts of electric motor, including motor control. A motor controller is a device or group of devices that serves to govern in some predetermined manner the performance of an electric motor. A motor controller might include a manual or automatic means for starting and stopping the motor, selecting forward or reverse rotation, selecting and regulating the speed, regulating or limiting the torque, and protecting against overloads and faults.
