Woodworking Machinery Phase Converters

Phase converters for woodworking equipment

Woodworking shops come in all sizes. Larger facilities generally are located in areas already served by three-phase power, but not always.

For the small and medium size shops, a woodworking machinery phase converters is often the most cost effective alternative.

A rotary converter can supply power to multiple machines.

A typical shop might include a 5HP sliding table saw, 5HP planer, 5HP dust collector and edgebander with several small motors and glue heater.

This arrangement of equipment could easily be fed from a single converter with a rating no larger than 10HP.

What are woodworking machinery phase converters?

Rotary Phase Converters draw energy from two-single phase lines which make use of a generated motored as a source for energy.

Woodworking machinery phase converters can merge with the other lines to produce power. 

3 types of rotary phase converters

Standard Rotary Phase Converter 

  • Pro-Line (PL) with digital start circuit
  • Digital Rotary Phase Converters

– Smart-Boost™ (SB) with digital current boost mode

– Smart-Phase™ (SP) with active digital voltage balancing

  • Rotary Converter Control Panels

CP (add your own idler motor)

Why invest in a Rotary Phase Converter

It is true there are other options out there to get three-phase power to your equipment.

Each option has its pros but it does come down to what is affordable for you and your situation.

The options are to get three-phase power through your utility line, a gas or diesel generator, or through a rotary phase converter.

Three phase generator is a good option if there is not power at the site.

They can run on gas or diesel fuel.

Generators are also available in both single-phase and three-phase options.  There are many different sizes available depending on specific needs.

The price is also reflected by the size of the generator and can range greatly.

When someone thinks of getting three phase power they think of Utility three phase. 

Characteristics of woodworking machines

Woodworking machinery are rather easy to start and not to severe.

This includes saws, drills, wide-belt sanders, boring machines, routers, among others.

All machines must be treated according to its operating characteristics.

Severe loads that run at high speed include shapers, jointers, and planers.

Edgebanders have a mix of frequency drives and glue heaters which can become problematic.

A well informed converter representative should be able to sort through the specifics and recommend an appropriate selection. 

What you must know in order to apply a woodworking machinery phase converters in your shop

Any load can be operated from a phase converter.

Careful sizing is the key to a successful installation.

It is important to be familiar with HP or KW ratings of each machine that you will be running.

You must also find out which machines will be operating together.

These steps are important in order to make sure you are getting a converter of the right capacity.

Service size

Sometimes great plans get sidetracked when the available service is inadequate to supply the equipment to be operated.

Some may ask how much single-phase service is needed to run a line-up of machines. 

Their is no limit on how much 3-phase equipment you plan to run.

If you don’t have enough single-phase service you don’t need to worry about what size converter to purchase.

In order to supply Single phase loads such as lighting, HVAC, single-phase machinery, etc you need to have enough service over and above what is needed.
