The General Application Guide will help you determine the suitability of an Autogen Model to your particular machine.
Select a converter with a hp range that fits the 3-phase motor you want to operate. Smaller motors that the converter’s range may be operated only while a motor in the converter’s range is operating.
Special Duty—for air compressors, hoists and other high-inertia loads of short duration: Select the largest CD3 that will operate your motor hp. (Example: A 5hp air compressor uses the CD 14—rather than the CD 13—converter.) Do not oversize a CD3 converter expecting to get more hp. (Example: Do not use a CD 17 for a 10 hp motor.)
Our Autogen is a capacitor-start, capacitor-run device. Even though ours is the best on the market, no static converter will produce the quality of power that our Rotary converters provide. A motor operated at or near full-load continuously on any static converter will run hot and burn up. A rotary converter, however will allow continuous full-load motor operation. If economics keeps you from buying a rotary phase converter, an idle 3-phase motor may be operated with the Autogen to increase power with little additional electrical cost. This idea was the “grandfather” of the modern rotary converter, and still works well on many machines.
The Idle motor acts as an “electrical flywheel” to carry heavily loaded motors along, and also permits operation of small motors on a large static converter. It works best on GWM’s converters, which include motor-run capacitors to boost the idle-motor’s performance and reduce operating current.
The idle motor method should not be used on CNC, modern high-efficiency motors or other specialized equipment. Consult Smith Electric Motorworks if you have questions about your application.
