VFD Training

This VFD training is to gives you the basic facts about VFD and how they work and assist you in finding the right VFD for your application.  A VFD are used on AC and DC motors to manage and control speed, torque, acceleration, deceleration and direction of rotation of a machine.  A VFD are mostly used to optimize the machines or motor and to improve product quality, production speed, save energy and safety.  In the beginning, VFDs  as a relatively and cost effective method of variable speed, control was poor at best.  But in recent years, with new VFD technology has evolved into highly sophisticated digital microprocessor control with high switching frequency IGBTs power devices.  The two significant benefits has been the cost and reliability and the significant reduction in size.

VFD Training - How a VFD works

A VFD in many cases are called "inverters" because the way a VFD works. The following will give you a simple design of a  AC VFD and how it works.

  1. AC power is applied to the input of the VFD and feeds a bridge rectifier

  2. The bridge rectifier converts the AC voltage into DC voltage

  3. The DC voltage then feeds the DC buss capacitors on the VFD where is is stored for use by a transistor or Insulated-Gate Bipolar Transistor (IGBT)

  4. DC from the capacitors feed the input of the transistor(s)

  5. The transistor then continuously turns on and off at the appropriate frequency to build a new sine wave for use by the motor connected to the output of The VFD.  This process is called as inversion because it changes from one form to another then back again.

The voltage frequency in the US is 60 cycles per second and the unit of measurement is Hertz (Hz).  The VFD output frequency and voltage is variable and controlled by the speed at which the output transistor is continuously turned on and off.  Today the variable speed is control more by digitally and changed by the operator through programming, an operator interface, or by changing an analog input to the VFD that is programmed as "speed reference input".

VFD Training - Benefits of using a VFD

A VFD offers many benefits but the most significant is the energy saved.  With the use of a VFD it soft starts the motor by applying a low frequency and voltage ramping up the motor slowly, this avoids a high inrush of electrical current.  After the motor is started the voltage and frequency are increased at a controlled rate until the electrical current meets the electrical load requirements of productions.  By using a VFD a motor can reach 150 percent of its rated torque while only using 50 percent of its rated current.  Without the use of a VFD the motor will immediately draw full voltage at about 300 percent of its rated current while producing less than 50 percent of its rated torque.  This cause the equipment to run inefficiently and causes more wear and tear on the machinery because of the unbalanced inrush of power.

VFD Training - Application Guide

Before purchasing a VFD for a new or existing applications there are many factors to consider before making the final decision on what type of VFD should be use.  The following will give you a guidelines what you will need to look for.

  • Research the motor and VFD specifications

  • Know your application requirements

  • Know what VFD products that are available

  • Understand the feature of these VFD products to determine what one is appropriate for your applications

  • There are several different types of VFD not all drive manufacturers offer every type of VFD available in the market.  If you have your heart set on a certain product line, make sure the supplier offers the type needed for your applications.

VFD Training - Types of VFDs

The following are the most popular types of VFDs that are available and what type of applications they are used for.

V/Hz VFDs

These are most commonly used and the most basic.  These VFDs are for basic applications in pumps, fans, conveyors, blowers and others.  They do not require high starting torque, full motor torque at low rpm and speed feedback.  Most of these have some programming features for many applications.  Be certain adequate I/O and programming features are available to meet your applications requirements. 

Sensorless (open loop) Vector VFDS

These VFD are used where full torque is require throughout the motor speed range, such as lathe or mill applications.  These Sensorless Vector VFDs are also referred to as open loop vector drives.  They are made for more complex applications and should be applied where high starting torque or full torque operating at low RPM is required.  If you need speed feedback or extremely complex programming you cannot use a this type of VFD.

Closed loop vector VFD

These are more advanced and are used where applications require accurate speed regulation and feedback from the motor or require complex programming.  This type of VFD is often offered as a three in one and able to operate in all operating modes.

V/Hz sensorless Vector and Closed Loop Vector

These are the most advance of the VFDs, they are for complex and extremely efficient when properly applied.  These closed-loop vector technology has few limits in drive technology.  These VFDs are used in applications where superior speed regulation and torque performance are require.  The product features are phenomenal in these drives.

Before choosing a VFD for applications consult with TEMCo who will ask all the right questions and make an appropriate recommendation.  They can guaranteed to have the right VFD for your applications.  TEMCo is a leading distributor of top manufacturer and with their large inventory you will find the correct VFD at the lowest price.  TEMCo has been in business for over 40 years and with their highly trained staff of engineers and technical support people they can help you before, during and after your sale to make sure your operations is running smoothly in the shortest time.  TEMCo ships most products within 24 hours and they guaranteed the lowest prices.
