Professional Speed Control Devices – High-Performance Solutions Tailored to Your Needs

Greetings everyone,
If your systems require torque control, consider our high-performance and functional inverter models. These products are equipped with rich features such as built-in PLC functions, temperature sensor inputs, ammeter inputs, and pressure sensors. They are ideal for winding and unwinding systems and controlling basic machinery.

Although their prices are higher than other models, they are in a very competitive position when compared to rival products. These devices, which are rich in parameters and have many built-in function macros, are relatively more difficult to use. However, we provide videos and usage notes to make the commissioning process easier.

Why Do We Need Professional Devices? (Even though they are more expensive)

For critical applications, it is essential to maintain a stable pulling or releasing moment. In this case, while the load curve and motor current change inversely with speed, the line current and motor power remain constant. Winding-unwinding and lifting-lowering applications in cranes are examples of such applications.

The reason for the inverse relationship between torque and speed is as follows: For example, in winding applications, we want the material to be wound at a constant tension. In this case, the pulling force and linear speed must remain constant. Due to the Fv=Tw equation, when the diameter decreases, the torque decreases, and when the diameter increases, the torque increases. To maintain constant speed, as per the v=2pin/60 *d/2 equation, the speed must decrease as the diameter increases. Therefore, as the diameter increases and the speed decreases, the torque increases.

For applications requiring high torque after a stop, it is appropriate to choose speed control devices with 150% loadability. As in crane lifting motors, the 150% selection will also be accurate for applications with an impulsive load curve, such as eccentric presses, saws, and grinders.

Alternative Solutions: Standard Speed Control Devices

If you do not need these types of features, our standard speed control device (VFD) models also offer similar functions. These products provide more economical solutions tailored to your needs, and you can still improve the efficiency and control of your systems.

In conclusion, professional speed control devices offer suitable solutions for high torque and critical applications, while more affordable standard speed control devices are designed to meet your general needs. By choosing the right model according to your needs, you can increase the performance and reliability of your systems.
