There are many reasons why the VFD is a popular choice for consumers, as other controllers are readily available. The most important reasons for the popularity of VFDS are low energy consumption capacity and initial setup costs. In terms of energy consumption, the VFD is more efficient than any controller device in the same market segment. Thus, in large factories and workshops that require more horsepower motors, VFDS offer low power consumption, which reduces the amount of energy bills and provides opportunities for cost savings.
The VFD limits the inrush current under motor start and stop conditions, which also reduces the inrush load in the supply line and provides a safety margin for expensive motors.
In addition to the above advantages, VFDS can reduce system maintenance costs. No additional expensive electrical connections and control operations are required. There is the option to connect multiple motors that can be controlled using a single VFD, further reducing additional system setup costs.
Disadvantages of VFD
However, despite the above advantages, VFD systems also have some disadvantages. The main drawback of VFD systems is the initial setup investment. For factories or workshops that need to control multiple high-horsepower motors using VFDS, high investment is required.
In addition, the VFD causes the motor to heat up and requires a special motor structure. The construction requires a special type of motor insulation, and the motor needs to be specified for the inverter rating application.
Another major disadvantage of VFD is that the main power line is seriously disturbed by distortion and notch harmonics of the line. Therefore, under operating conditions, other devices connected to the same power cord can also be obstructed.
However, advances in the modern semiconductor industry have greatly improved the structure of modern VFD systems. Before the era of solid-state devices, rotary machines were the main components used to manufacture VFDS. In the modern microprocessor era, VFDS are equipped with various protections, such as undervoltage, overvoltage, thermal overload protection, etc. Have proper control equipment. Motor applications in this industry consume 25% of the world’s electrical energy, and using VFDS can effectively control this consumption.
