Description
 
The use of power relays to provide a switched sequence of events for starting, stopping, foward and reversing of electrical machines has been traditionally carried out by Electromagnetic control gear. The application of these devices is widely used today and therefore the principles need to be understood. The EMC Electromagnetic Motor Control 60-070 provides study methods and terminology associated with the implementation of control devices in some of the most commonly used circuits for control of ac and dc machines, to a level that can be understood by both maintenance engineers and technicians alike. The equipment consists of a wide range of control gear that is provided on three panels. One has electromagnetic contactors, and the other two have pushbutton and rotary switch gear and indicator lights.
