Do you have a selection guide for phase converters vs. VSDs etc?

The simple table below can be used a guide to select the most appropriate electrical power solution for your circumstances. Just answer questions in numerical order until you locate a suggested solution. As with all such guides it is not perfect but you are welcome to contact us if you need more help.

The general message is that remotoring and/or installing an inverter drive might suit the simpler and/or single machine workshops, but that a phase converter will suit a wider range of machinery. If buying a phase converter it is almost always worth stretching your budget to a rotary phase converter rather than a static.

*Table of phase converter selection guidelines*		About your machinery
		Only one three phase machine				Multiple three phase machines
		No motors	One motor	One motor & suds pump	Multiple motors
Questions about your circumstances	1. Three phase cheap to install or easy to move premises?	Yes = Install a three phase electrical supply at your premises or move to premises with three phase.
	2. Are the motors easy to replace?		Yes = install single-phase motor unless high starting torque required.
	3. Accurate speed control necessary?		Yes = consider a variable speed inverter drive if a package is available for your machine tool.
	4. High starting torque or high speed required?		No = consider a static phase converter (but you will get better performance from a rotary converter).
	5. All other cases.	It is probably most cost-effective to install a rotary phase converter.
