DOL System for Electro Motor

DOL System for Electro Motor

Engineering Basic Training
The basic ability of engineering in hotels or buildings is to understand the basic control of electric motors. because almost all equipment in hotels uses a system like this.
The DOL- Direct online system using the ON-OFF push button is widely used in hotels, for pumps, exhausts, and many more.
As a basic training material, we provide a simple schematic so that basic engineering knowledge increases.
After understanding, it is hoped that it will be quick to analyze the troubleshooting if there is a problem with the electric motor control system.

 

Here are some examples of how the DOL- Direct online system is used in hotels:

  • Water pumps: DOL starters are commonly used to start water pumps in hotels. This includes pumps for drinking water, swimming pools, and landscaping.
  • Exhaust fans: DOL starters are also used to start exhaust fans in hotels. This includes fans in kitchens, bathrooms, and public areas.
  • Elevators: DOL starters are sometimes used to start elevators in hotels. However, more complex starters are often used for elevators, such as variable frequency drives (VFDs).
  • HVAC systems: DOL starters can also be used to start HVAC systems in hotels. This includes systems for heating, cooling, and ventilation.

Here are some other examples of how the DOL- Direct online system is used:

  • Conveyor belts: DOL starters are commonly used to start conveyor belts in factories and warehouses.
  • Fans: DOL starters are also used to start fans in a variety of applications, such as industrial ventilation systems and cooling systems.
  • Pumps: DOL starters are used to start pumps in a variety of applications, such as water supply systems, irrigation systems, and sewage treatment systems.
  • Compressors: DOL starters are also used to start compressors in a variety of applications, such as air conditioning systems and refrigeration systems.

The DOL- Direct online system is a good choice for many applications because it is simple, reliable, and relatively inexpensive. However, it is important to note that DOL starters can cause a high inrush current when the motor is started. This can cause problems with electrical equipment and wiring, so it is important to size the starter correctly.
