Everything you want to know about frequency converters
A frequency converter (frequency converter) or also called drive in the field, is a type of motor controller that an electric motor drives by changing the frequency of a supplied power supply while the voltage varies with it so that the torque is maintained. In addition, the frequency converter can also control the motor starting and stopping continuously during starting and stopping.
Usually AC drives are used to control the speed of a motor by changing the frequency of the rotating field. The term speed control is often used here because it ultimately ensures an adjustment of the engine speed.
There are many application possibilities of frequency inverters. There are drives for small drives such as a conveyor belt of several hundred watts. But also large drives of, for example, underwater motors of 6 megawatts. It doesn’t stop there, because agitators, water transport at water boards, extruders, cranes, fans and electric vehicles also use drives for the food industry. Small frequency inverters are used for light drives and mounted in the wall. With heavy drives, the drives are built in control cabinets.
Why a frequency converter?
A frequency converter has many reasons why you should apply it. For starters, it lowers the inrush current. When using the drive, the motor inrush current will not exceed 1.5 times the rated motor current.

What are the advantages of the Siemens Sinamics series?
The 6 advantages of the Siemens SINAMICS series:
4. Safety Integrated
5. System solutions
The user-friendly and scalable Siemens Sinamics series frequency inverter brings many advantages. Firstly, it gives performance and functionality to the need and thus is really versatile. From low voltage and medium voltage regulators to direct voltage regulators. This drive offers future-proof and turnkey solutions for all applications.
Second, it has higher productivity and is forward-looking. An important step towards digitized data analysis is digital extended drive components. Digitization offers new dimensions to realize in availability, productivity and efficiency. Valuable insights are provided by analyzing the control data.
A third advantage is that the frequency converter is easy to use for engineers. The tasks are easy to select, parameterize and integrate. It couldn’t be simpler than this.
The fourth advantage is that the drive has maximum safety for operating and maintenance personnel. These are already integrated in the frequency converters. This also gives benefits such as short response times, less wiring and profitability.
Fifth, the SINAMICS controllers fit seamlessly on SIMOTIC motors and SIMOGEAR gear units and thus interact perfectly with each other. This saves you time, money and gives you a sustainable lead in the market. In addition, it has reliable and fast communication via PROFINET.
What are the advantages of the Schneider Electric Altivar series?
The 4 advantages of the Schneider Electric Altivar series:
1. Machine Safety
2. Versatile products
3. Efficient performance
4. Long life
Firstly, the low voltage AC drives provide machine safety. This is due to proper motor control and accurate speed control in any situation. Secondly, the range consists of many different products for electrically controlling small and easy machines, but also for large advanced machines. Third, the Schneider Electric Altivar is made to perform as efficiently as possible at the highest level of quality. Finally, fans, pumps and conveyors can be started gradually without causing overload. This is very important and protects the machines which ensures a longer life.
