In the 1830′s, Michael Faraday made a discovery that has made work easier for all of us. While experimenting with magnets he found that lively a wire through a magnetic field would furnish an electric current. This experiment is leading because it led to the discovery of the operating principles of electric motors and generators.
A motor is a rotating engine that converts electrical power into mechanical energy. A generator, on the other hand, is a rotating engine that converts mechanical power into electrical energy.
When we talk about electric motors and motor repair, we are typically referring to big market equipment, however, the truth is that electric motors are at work all nearby us at home, work, school, and even at play.
Electric motors play a very leading part in furnishing power for all types of domestic and market applications. Their versatility, dependability, and cheaper of carrying out cannot be equaled by any other form of motive power.
Currently, there is a growing request for electric motor sales, as well as experienced repairing experts. When choosing a sales or mend location make sure to check that they are Easa members and have been trained in the latest Ieee and Nema specfications.
These motors, the engine they drive, and motor controller are interrelated. They need to be determined a holder when choosing a specific gadget for a singular application.
In general, five basic factors sway the selection of a controller:
- Electric Service-Establish whether the service is dc or ac. If ac, rule the whole of phases and the frequency-in addition to the voltage.
- Motor-
- Operating Characteristics of the Controller-
- Environment-
National codes and Standards-Motor and motor operate equipment are designed to meet the provisions of the National Electrical Code (Nec):
Occupational protection and health Act (Osha)
National electric Manufacturers relationship (Nema)
Underwriters Laboratories (Ul)
Each of which furnish protection and practical information in the application of electric motors and controls.
There are new governmental standards on efficiency of electric motors (Iee-84I ).
