3. AC Drives / VFD

What Is A Variable Frequency Drive?

Variable Frequency Drive (VFD) is a device that helps you in converting the fixed voltage and frequency of the input power provided to the motor, into variable voltage and frequency. This conversion regulates the functioning of your electric motor.

Majority of applications need variable speed during peak load and a constant speed when the load and current is normal. The key use of a VFD is to maintain the speed of a motor at a constant level even if there are disturbances in load and input.

Types Of Electric Drives

1. Eddy-current Coupling

This VFD is present between the fixed speed motor and the application driven by the motor. It contains a fixed speed motor and a variable speed motor. Both of these components are separated by a small air gap.

2. DC Drives

DC drives involves the DC converter turning the AC supply of power into a DC voltage of variable magnitude. This voltage is supplied to the armature winding of the concerned DC motor. These drives make use of thyristor technology and are used in an array of applications.

3. AC Drives

There are three major types of VFDs here, all of which convert AC input into DC, followed by changing DC into a variable AC output with the help of an inverter. The three different AC VFDs are Current Source, Voltage Source and Direct Conversion drives.

Important Features of VFDs

Now that you are well-versed with the different types of VFDs and applications of the same, let us look at a few key features of the same.

Line Voltage

  • It is important to state the operating voltage of a variable frequency drive. This reading generally comes to 240VAC or 480VAC. A voltage variation of 10% can be allowed in the reading.
  • It is advisable to consider power deviations while recording a voltage reading for any major application.

Continuous Run Current Rating

  • This is the value depicting the maximum root-mean-square (rms) current your VFD can safely handle under all operating conditions with a constant ambient temperature (usually 40 degrees Celsius).
  • This rating is important because it should be equal to or more than the motor ball load sine wave currents for proper functioning of an electric motor.

Overload Current Rating

  • In simple terms, this is the maximum amount of current your VFD can produce for a given period of time. It is expressed as an inverse time/current rating.

4. PLC / HMI

PLC (Programmable Logic Controller) and HMI (Human-Machine Interface) are integral components of modern industrial automation systems. PLCs are programmable electronic devices used to control and automate various processes in manufacturing, such as machinery operation, production lines, and industrial processes. They are designed to monitor inputs from sensors and other devices, execute control algorithms, and generate outputs to control actuators and machinery.

On the other hand, HMIs are user interfaces that allow operators and technicians to interact with PLCs and other control systems. HMIs typically consist of graphical displays, touchscreens, and input devices such as buttons and switches. They provide real-time data visualization, control capabilities, alarm notifications, and system diagnostics, enabling users to monitor and manage industrial processes efficiently.

PLC / HMI

Together, PLCs and HMIs form the backbone of industrial automation, enabling seamless control, monitoring, and optimization of complex manufacturing processes while improving productivity, reliability, and safety.

An HMI is typically easier to use than a PLC because it has a graphical user interface that can be controlled with a mouse or touchscreen. This means that people without much knowledge of programming can still use a SCADA and HMI System to control machinery

5. Loadcell

A load cell is a transducer used to convert mechanical force or weight into an electrical signal. It is commonly used in industrial applications to measure force, weight, or pressure. Load cells are essential components in various systems, such as weighing scales, industrial automation, material handling equipment, and testing machines.

Load cells work on the principle of strain gauge technology, where strain gauges are bonded to a metal structure that deforms under applied force. As the metal structure deforms, the strain gauges experience a change in resistance, which is converted into an electrical signal proportional to the applied force. This signal is then amplified and processed to obtain accurate measurements of the force or weight being applied.

There are different types of load cells available, including:

  • Compression Load Cells: These are designed to measure compression or pushing forces.
  • Tension Load Cells: These are used to measure tension or pulling forces.
  • Shear Load Cells: These are used to measure shear forces.
  • Bending Beam Load Cells: These are commonly used in weighing scales and industrial applications.

Load cells are calibrated to ensure accurate and reliable measurements. They are used in various industries such as manufacturing, aerospace, automotive, healthcare, and agriculture, where precise force or weight measurements are required for process control, quality assurance, and safety.
