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 inviting a wire through a magnetic field would yield an electric current. This experiment is leading because it led to the discovery of the operating system of electric motors and generators.
A motor is a rotating engine that converts electrical energy into mechanical energy. A generator, on the other hand, is a rotating engine that converts mechanical energy into electrical energy.
Electric Motor Drives
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 colse to 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 economy of carrying out cannot be equaled by any other form of motive power.
Currently, there is a growing inquire for electric motor sales, as well as experienced repairing experts. When choosing a sales or fix location make sure to check that they are Easa members and have been trained in the newest Ieee and Nema specfications.
These motors, the engine they drive, and motor controller are interrelated. They need to be carefully a box when choosing a exact gismo for a singular application.
In general, five basic factors work on the choice of a controller:
- Electric Service-Establish either the assistance is dc or ac. If ac, decree the amount of phases and the frequency-in increasing to the voltage.
- Motor-
- Operating Characteristics of the Controller-
- Environment-
National codes and Standards-Motor and motor control 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 supply protection and practical facts in the application of electric motors and controls.
There are new governmental standards on efficiency of electric motors (Iee-84I ).
