Soft Starters

With soft starter products, problems that may occur in your motors or electrical installations can be eliminated quickly and effectively. The models in this product group are also called soft starters. Soft starters are especially preferred in commercial and industrial facilities.

You can protect your electronic devices with soft starter connection. The systems focus on energy efficiency and eliminating possible malfunctions before they occur. In the facilities and enterprises where they are used, they are generally preferred for purposes such as reducing expenses and protecting electrical installations. Related products work in a way to minimize the vibrations observed in electric motors and prevent problems such as motor locking before they occur.

What is Soft Starter?

Soft starters are produced with model options with different technical features to meet the needs of different businesses. These electronic devices have models operating at different kW values. Soft starter devices are increasingly preferred to ensure that electric motors or installations do not compromise the maximum level of safety.

In order to avoid problems such as faulty grounding and motor locking, faults must be prevented before they occur. You can use soft starters for electronic devices that operate smoothly at maximum performance. These efficiency-oriented electronic devices minimize the level of vibration as they take up little space.

What is a soft starter? As their name suggests, these devices allow motors to start softly. The control of electric motors is an extremely important issue for industrial plants. Systems that allow the current to be controlled during the acceleration phase of the motor do not allow the electrical stress to increase.


Soft Starter Price

Soft starters are used for sudden voltage drop and for the grid-connected devices to function as desired. It is known that the use of soft starters provides various advantages to businesses. These benefits, especially the control of power consumption and prevention of possible failures, can be summarized as follows.

Working with the world’s leading soft starter manufacturers such as ABB, AuCom and Siemens, Kraftek offers its customers a wide range of stock options. Electric motors can frequently malfunction due to their structure. How does a soft starter work? Soft starter systems allow the motor to rise slowly in order to contribute to reducing mechanical shock.

Soft starter systems can make a difference in your business, as they also have benefits such as increased system safety or extended device life. How do motor soft starters work? The main circuits of these systems contain thyristors and the motor voltage is regulated by printed circuit boards.

Siemens Soft Starter

Siemens is one of the world’s leading electronic system manufacturers. It stands out with its model diversity in the soft starter product group. The devices are diversified according to different motor options and energy requirements. It provides a soft start of the motors and an effective protection against the risk of voltage drop.

One of the areas of use of soft starters is waste water pumps. These devices are used to reduce maintenance costs and prevent pump blockages. The devices operate at different kW values. Different values such as 15 kW and 37 kW are used in different

The use of soft starters can extend the life of equipment by reducing mechanical wear and tear. They also provide a more efficient use of energy with lower energy costs and less electrical stress. These devices are often used in combination with a component called a drive.

Drives help control the speed, torque and electric current of the motor. This can be used to optimize a motor’s performance and further reduce energy use. Soft starters are often a good alternative to more complex variable speed drives (VFD).


Soft Starter Connection

Soft starters are usually connected directly to three-phase electric motors and control the network voltage. They have input and output terminals to control the speed and torque of the motor. A typical soft starter connection may include the following steps, reviewing the user manual is the key to accessing safer and more accurate information.

  • The main electrical line to the power supply is connected to the soft starter’s input terminals (L1, L2 and L3).
  • The output terminals (T1, T2 and T3) of the soft starter are connected to the power input of the motor.
  • The soft starter’s control terminals are then connected to a control signal source such as a start/stop control button or PLC (Programmable Logic Controller).
  • If present, the thermal protection relay and other safety devices must be properly connected.
  • The soft starter must be properly grounded from the main power line and towards the input of the motor.
  • Finally, a test is performed to verify that everything is connected correctly and that the soft starter is working correctly.
