Variable Frequency Drives (VFDs) - A special type of
adjustable-speed drive that regulates the rotational speed of an
AC electric motor by governing how often electrical power is
delivered to the motor.

Baldor Variable Frequency Drives
- Variable motor speed use to be achieved by using a
wound rotor motor or variable rotor resistors. The new
more efficient and effective way to achieve this variable speed
today is with variable frequency drives. Baldor Drives now
offers a complete solution to your motor control needs.
WEG Variable Frequency Drives
- Dedicated initially to production of electric
motors, the company started expanding its activities in the 80's
with the production of generators, electrical components,
industrial automation products, power and distribution
transformers, liquid and powder paints and electroinsulating
varnishes.
Find out more about WEG and
the quality products they offer.
Variable Frequency Drive Basics - Learn what a
variable frequency drive is, how they work and what applications
they are used for. Variable speed drive technology is a
cost-effective method to match driver speed to load demands and
represents a state-of-the-art opportunity to reduce operating
costs and improve overall productivity.
AC Variable Frequency Drives - The demand for
highly reliable AC power has grown in the last decade. The
advancement in electronics and high power microprocessors is one
of the reasons for the increase.
The
main power components of an AC drive, have to be able to supply
the required level of current and voltage in a form the motor
can use.
Variable Frequency Drive Motors - Variable
frequency drive motors control air handlers, chillers, pumps,
conveyors, machine tools, mixers, draw lines, and many other
applications once considered strictly DC applications, or
constant speed. Find out more about the knowledge and
technology of variable frequency drive motors.
Soft Start Drives -
Soft start drives are another form of reduced voltage starter
for AC induction motors. It is similar to a primary
resistance or primary reactance starter in that is in series
with the supply to the motor.

"Phase Converters"
- VFDs, also known as variable frequency drives can
be used to control motor only type of loads. They cannot be used
for any type of non-motor 3 phase load. Find out more about VFD

VFDs as Phase Converters - There are three ways
that you can convert 1P to 3P. You can use a static converter,
rotary converter or a VFD. Find out why choosing a VFDs as a
phase converter has its disadvantages.
Electric Motors - Electric motors convert electrical
energy into kinetic energy. Electric motors have rotating coils
of wire which are operated by the magnetic force exerted by a
magnetic field on an electric current.
