A static phase converter can be an important power source for specific pieces of machinery. But what exactly is a static phase converter? How does it work? What types of machinery can it be used to power? What size phase converter do I need? We have created an outline of sizing tips to give you the basic knowledge you need to determine if you need a static phase converter or if you need a rotary converter instead.
What Is a Static Phase Converter?
A static phase converter is a startup device used to power three-phase motors that are on single-phase power. This means that the phase converter generates three-phase power to start the equipment's motor. Once the motor has started, the static phase converter drops out, and the motor will run on single-phase power. This means that only two of the three windings within the converter will receive power after startup, reducing the horsepower output by about one-third to one-half of its full power.
This makes a static phase converter ideal for operating motors that don't require full power output continuously, but they're not recommended for equipment that requires continuous high load output. However, for hobby applications or occasional use where motors don't require full power, a static phase converter is a cost-effective option.
What Size Phase Converter Do I Need?
Phase converters come in various sizes, with different limits on their power output. A sizing tip that you will need to utilize prior to purchasing a static phase converter is choosing a piece of hardware that is rated for the horsepower of the motor you wish to start. Remember, these are intended for easy to medium motor loads.
Now, you might think that buying an oversized phase converter will simply ensure you have enough power to start up any motor. However, it is possible to oversize your converter, and this can lead to some issues. An oversized static phase converter produces too much startup power, which can excite the motor and cause it not to start.
Additionally, it's important to note that a larger phase converter won't help the motor to run on full power; it will still operate at two-thirds to one-half of its horsepower once the motor has started and the static converter has disengaged.
Do You Need a Static or Rotary Phase Converter?
Static converters do have their limitations, so it's important to know whether a static phase converter will work for you, or if you need a rotary phase converter. If you follow our sizing suggestions prior to choosing a static phase converter, you will be able to operate various types of equipment at acceptable loads. Static phase converters can be utilized to operate equipment such as bench grinders, chop saws, drill presses, meat slicers, table saws, belt-drive band saws, and industrial dough mixers.
Additional Types of Hardware to Operate With Static Phase Converters:
- Sewing Machines
- Above-Ground Pumps
- Horizontal Conveyor Belts
What Types of Equipment Require a Rotary Phase Converter
A sufficient amount of hardware in various industries will not function without a rotary phase converter that is the correct size and capacity for specific applications. Various types of equipment that require a rotary phase converter include air compressors, bailers, direct-drive band saws, vehicle lifts, granite saws, hoists, shears, thickness planers, and vacuum pumps.
