Basic principle. An electric motor is a device converting electrical energy into mechanical energy (generally a torque). This conversion is usually obtained through the generation of a magnetic field by means of a current flowing into one or more coils. Electrical energy.
19 lut 2018 · In many commercial and industrial applications, quite a few electric motors are required, and it is often desirable to control some or all of the motors from a central location. The apparatus designed for this function is the motor control center (MCC).
Read a basic line diagram. Describe the construction and operating principles of manual starters, electromagnetic contactors, and electromagnetic motor starters. Explain the need for motor overload protection. Briefly describe the operation of thermal and electronic overload relays. Describe the advantages of reduced-voltage motor starting.
Wiring diagrams, sometimes called “main” or “construc-tion” diagrams, show the actual connection points for the wires to the components and terminals of the controller. They show the relative location of the components. They can be used as a guide when wiring the controller.
