Phase Converters

Rotary Phase Converter

The most common and universal type of phase converter is a Pro Line rotary phase converter. NAPCco proudly builds two of the finest on the market today – The “Pro Line” Rotary Converter and the Smart-Boost™ Digital Rotary Phase Converter. A rotary phase converter uses an induction generator (sometimes referred to as an idler) to produce 3 phase power. The 2 single phase lines are used to energize the induction generator; in turn the induction generator produces the 3rd line of power (voltage). This 3rd line of power is joined together with the single phase lines to make 3 phase converter power.

CNC Balanced Rotary Phase Converter

DSCN5738When used with CNC machines and/or other voltage sensitive equipment, a CNC balanced rotary phase converter maintains a more stable voltage balance output. Our “Pro Line” converters are CNC balanced.

UL Industrial Control Panels

UL Rotary Phase Converter - DSCN5723-50This is a rotary phase converter control panel that is built per UL (Underwriter’s Laboratories) specifications and carries the UL Listed markings.  Our generator idler motor made by Baldor Electric is a UL recognized component.  North America Phase Converters is a UL 508A Panel Builder.

Rotary Phase Converter Control Panel

Rotary Phase Converter Control Panel - DSCN5608-50The control panel is half of a rotary phase converter. This is for the customer that has his/her own 3 phase motor to use as an idler motor. We are just supplying the control panel. The rotary phase control panel includes a motor starter, voltage balancing and input and output terminal blocks.

Static Phase Converter

Static Phase ConverterTo start a 3 phase motor but run it with the 2 single phase lines a static phase converter is used. A static phase converter consists of one or more start capacitors and a start relay. The start capacitors produce electricity across the third winding of a motor during start up. Once the motor is up to speed the phase converter capacitors are disconnected from the motor winding. The motor load is now running on just the two single phase lines of power (in essence, the motor is single phasing). North America Phase Converters offers two lines of static phase converters – Heavy Duty and High-Low Double Horsepower.

Digital Rotary Phase Converter

SP-10 websiteUnlike other converters, a digital rotary phase converter uses solid state electronic controls along with an induction generator to produce the 3rd leg of power.  Then it uses a microprocessor to monitor the output voltage of the digital phase converter, and maintains a 2-3% voltage balance under any load condition. North America Phase Converters proudly offers our Smart-Phase™ Digital Rotary Phase Converters.
