Phase-A-Matic PAM-7500HD PAM Series 50 to 75 HP Static Phase Converter, Heavy Duty

STARTS THREE-PHASE MOTORS FROM SINGLE-PHASE POWER AT 2/3 RATED HP*

IMPORTANT: Static Converters do not produce constant 3-phase power; they "jump-start" your 3-phase motor to run on single-phase power. Be sure to read all information provided.

NOT FOR USE IN WET OR DAMP LOCATIONS

*Refers to wye-wound motors; delta-wound motors will run at 50% rated HP. Delta-wound motors are very rare in the USA, occasionally being found on some imported equipment, and are particularly found on German and Italian machines.Phase-A-Matic™ Static Phase Converters have been developed, tested, and thoroughly proven over a 46 year period demonstrating exceptionally high reliability and long life. These converters are the workhorse of many commercial uses and multitudes of home shop machines.

Designed especially for running three -phase 230V Machine Tools and Motors from single -phase 230V power.

Features:

• Immediate Delivery From Stock
• No More Changing Motors or Switch Gear
• Simple Installation
• Reliability Has Proven Exceptionally Good

Applications:

• Lathes and Mills
• Grinders and Drills
• Saws and Metal working and Woodworking equipment
• Printing Machines and Equipment
• Sewing Machines and Garbage Disposals
• Food Processing Equipment
• Meat Grinders and Dough Mixers
• Food Blenders Elevator Belts
• and numerous other uses.

METHOD #1

Reduced HP method. Using the PHASE-A-MATIC Static Converter alone will produce approximately 2/3 normal HP.* It runs MOTOR LOADS ONLY. This method is inexpensive and the most popular. It provides excellent results on most machine tools and can be for numerous other uses. Motor speed is not changed and most 2-speed motors, power feeds, coolant pumps, etc. will operate. Motor will instant reverse, there is nothing to change and all switch gear will work normally. *Refers to wye-wound motors; delta-wound motors will run at 50% rated HP. Delta-wound motors are rarely made in the United States but are occasionally found on some imported equipment and particularly on German and Italian machines.

METHOD #2

Full or close to full HP method. Make your own type of ROTARY CONVERTER using the PHASEA-MATIC Static Converter. In conjunction with a three-phase motor used as an idler motor, this can produce full or close to full HP. When running unloaded, the windings of the motor function as a rotary transformer or generator while consuming little extra power. The idler motor needs to be a minimum of 50% larger than the largest motor that you want to run to accommodate the higher starting current. A good quality 3600 RPM three-phase wyewound 230V motor is the best choice. 1800 RPM motors can be used on applications not heavily loaded. Used three-phase motors are inexpensive and readily available. When using this method, it is possible to run multiple machines as long as the idler motor is large enough to handle the largest load it would ever have at any one time. For instant reversing of the load motor, as in rigid tapping, the idler motor must be a minimum of twice the HP rating of the load motor, and perhaps more. The Static Converter is sized to the HP of the idler motor, not the load motor(s).

LIFE EXPECTANCY

The Static Converter has been in use for approximately 52 years and has already proven itself to be extremely reliable when properly applied. Phase-A-Matic™ was recently able to purchase back the first one that was ever sold, and it is still working fine. It is reasonable to expect the converter to be in good working condition and service for 20 or 30 years or more. We continue to hear back from customers who have them still running their equipment faithfully after 20 years and more. Uses include: Lathes, Mills, Grinders, Drills, Saws, Metalworking and Woodworking Equipment, Printing Equipment, Sewing Machines, Garbage Disposals, Food Processing Equipment, Meat Grinders, Food Mixers and Blenders, Conveyer Belts, and numerous other uses.
