Motor protection covers the disconnection types, overcurrent and overload provisions, and other protection devices.
Motor starting is a vital consideration, as the starter must supply the motor with sufficient current to bring it up to speed under the worst-case voltage and load conditions. Six types of reduced voltage starters are described.
Under speed control, you will learn about five external drives along withmulti-speed and adjustable-speed motors as well as controls.
The section on drive types provides a complete look at how drives impact the operation of equipment.
You'll find detailed explanations of how adjustable and variable speed drives operate, and separate sections on:
~ Mechanical Drives
~ Speed-Flow Reduction Drives
~ Multi-Speed Motors
~ Adjustable Speed Drives
~ Direct Current Drives
Four methods other than allowing a motor to coast to a stop are also discussed.
System Requirements
~ Windows 95 or higher
~ Pentium 90 or higher
~ 16 MB RAM or more
~ 4X CD-ROM or faster
