What Can I Do With A Difficult Motor Application?
Some motors operate under extreme starting and running loads and require special consideration. A rotary converter that is at least two-and-one-half times the size of the largest operated motor is used. Applications for this type of rotary converter might include: Submersible (deep-well) water pumps 20 HP and larger, high-speed geared-head lathes manufactured in the Far East and Europe, and/or lathes with multi-speed motors, some fertilizer blenders and cement mixers, cement augers, soft ice-cream machines, most hydraulic brakes, shears, compactors, pallet notchers, fire sirens and other tough loads.
When thinking about purchasing a three-phase converter, be sure to check out an application guide to find out which one, rotary converter or static converter, works best for your needs.
When Do You Need a Static vs. Rotary Converter?
Static phase converters provide motors or machinery power in single phase. This is how they are different from rotary phase; static phase converters do not generate three-phase power continuously like the rotary phase converters.
Sometimes static phase converters are not well suited for motors or machines that operate continuously close to the maximum rated horsepower. When used in the wrong applications, static phase converters can damage the motors and machines that they are meant to operate. When machinery requires three-phase power, it must get true three-phase power of a rotary converter. Static phase converters damage the machinery they are set up to run, because they only allow the motors and machinery to run at half or two-thirds the power they were designed for. Then when the machinery is put under its full-rated load, the motor or machinery will stall out causing it to overheat and burn out.
But when is it more appropriate to use static? For lightly loaded machine tools, such as drills, mills, low-speed lathes fitted with a clutch, pedestal grinders, bandsaws, conveyors, shapers, motor-driven welders, and dishwashers, you may wish to check out static phase converters.
On a multi-motor application, it is better to use a rotary converter of equal HP to the largest motor operated. It is wise to choose a rotary that is at least one size larger than the largest operated motor, even on these lightly-loaded machines. The multi-motor load may then be three times the HP of the largest motor you operate.
Three-Phase is More Economical
Using a three-phase converter for your electrical needs is more economical. Why? A three-phase system is generally more economical, because it uses less conductor material to transmit electric power than equivalent single-phase or two-phase systems at the same voltage. How does this work? In a three-phase system, three circuit conductors carry three alternating currents of the same frequency, which reach their peak at different times. Taking one conductor as the reference, the other two currents are delayed in time by one-third and two-thirds of one cycle of the electric current. This delay between phases has the effect of giving constant power transfer over each cycle of the current and also makes it possible to produce a rotating magnetic field in an electric motor. Three-phase systems can save a person a lot of money in electrical costs.
Did you know…?
If you are in the market to purchase a three-phase converter, there are many opportunities out there, and you may be overwhelmed when trying to decide which converter model is right to fit your need. Whether you are searching for a converter to meet your irrigation needs on your farm, operating your embroidery or engraving machinery, or running and sander or saw in your shop, there is a converter out there for you. Many times, custom work can be done just to meet your specific needs!

What is the Difference in Types of Rotary Converters?
Whether you’re in the metal shop or operating farm equipment that requires a lot of power, rotary phase converters are often used to help you transition from AC to DC power or DC to AC power. The question is of all of rotary phase converters available, which one is the best to fit your needs?
In most cases, the answer to this question lies in the environment in which you are operating your converter. Some rotary converters are more suited for the outdoors, in home shops or businesses that are located in a more dirty setting. Other rotary converters are used for heavy computerized equipment in businesses and are designed for indoor environments. Talking with a developer about your particular use for your rotary converter can help you establish what you’ll need to find success in your business.
Phase Converters – A Big Investment Worth Making?
A phase converter can be a big investment.
When some people are thinking about possibly investing in a 3-phase converter, a question in their minds might be why are three-phase converters better than single-phase power?
Single-phase AC power is a lot like a pulsating shower head, compared to a flowing garden hose. This could lead to a subtle but persistent power interruption in single-phase and is the reason that single-phase motors above 5 Hp are rare and expensive.
By contrast, three-phase power flow allows for phase overlaps in the dead space that can occur in pulsating single-phase power. This overlap in power is the key to the smooth, continuous and universally adaptable power of three-phase.
Having that overlap created in three-phase power converters can equal higher productivity that can be a big pay off in the end.
