Single-phase ac motors are as ubiquitous as they are useful -- serving as prime power sources for a seemingly limitless array of small-horsepower applications in industry and home. Knowing how to ...

Many single-phase motors used with refrigeration-duty, semi-hermetic and hermetic compressors require an external relay to assist in starting. How much do you know about these necessary products? An ...

A synchronous and synchronous motors are the two main categories of ac motors. A synchronous and synchronous motors are the two main categories of ac motors. The induction motor is a common form of ...

THE first edition of this work appeared in 1904. Since then remarkable advances have been made in electrical engineering. A foremost place in this progress must be given to electric motors, and more ...
