Areas of application
The areas of application for electric motors are extremely diverse. From the small fans that cool the computer, to household appliances, to the large drives in industry with an output of several megawatts. We would like to present some examples from the industry and mobility sectors in the following chapters.
Use in industry
The areas of application of electric motors in industry are divided into different categories. They all have different requirements. Therefore, different motor types and designs are used.
- Drives for conveyor belts
- Drives for fans or pumps
- Drives for vehicles used to transport materials (e.g. forklifts)
- Drives for cranes or other lifting devices
- Drives for industrial robots.
- Synchronous drives, for example for rolling or printing
- Drives for winding and unwinding, for example sheet steel or paper (special requirement here: the speed must be constantly adapted to the size of the roll)
- Clock drives for cross cutters or flying saws (the material moves during the cut)
- Drives with non-uniform movement, such as those used for punching
- Drives for forming processes, for example presses
- Tool drives, for example lathes or drills
The efficiency of electric motors
The idea of protecting the environment has come to the fore in recent years, even with electric motors. The motors most frequently used in industry (low-voltage three-phase asynchronous motors) have their own efficiency classes. What is a scale from G to A (best) for a refrigerator is for low-voltage three-phase asynchronous motors in the power range from IE1-IE4 (best).
The currently valid status is shown in the following graphic
