Yes, and without the expense and difficulty of a phase converter! Simply use an Inverter/VFD that accepts single phase power ( most newer models do) and let it create its own three-phase, which is much more stable than ANY phase converter can produce. Just make sure to buy an Inverter rated for one size larger spindle motor ( ex. 2HP Spindle, 3HP Inverter). Go to www.ajaxcnc.com/partsources.htm to see where we buy ours!

Single-phase induction motors are just about the most common type of motor out there, and they'll run just about anything you can think of on your farm or in your industry. They are especially valuable for agricultural applications (irrigation systems, deep well pumps) and for any application using portable equipment, such as cement mixers and portable conveyors. For a more complete list, please click here.

All booth motors (except for a few) come standard with a 3-phase 208/230/460V/60HZ motor. Single-phase motors are available (up to and including 7.5 HP) for a small charge.

We make capacitor start/capacitor run induction motors (480V, 10- 200 HP; or 240V, 15-50 HP), which combine the very best features of other types of single-phase motors: They have a high starting torque, high overload torque, and higher efficiency, meaning they operate at a lower temperature than other types of single-phase motors of the same horsepower. You'll note we also offer larger sizes of single-phase motors (up to 200 HP) than you're likely to find anywhere else.

The application note here is a modified excerpt from our manual, which describes the wiring theory of both unipolar and bipolar motors to our system. It includes details on the double power mode of operations. The section shown here is an actual summary of wiring a 1.25 amp unit to one of our 0.6 amp controllers.

my logic says ,it can be used but i don't know its consequences or,side effects,if any,please help me. using a scott transformer, feeding two single phase loads, which are unbalanced, how dramatically could this affect the overall power system? Are power electronics and svc the only solutions to mitigate the problem? Which solution is most appropriate> My name is Jose Garcia, EE. My Company: AGC Electric & Recycling Contractors Inc., Miami, FL.

It is not possible for a transformer to present a balanced load to the supply and deliver a single-phase output. Changing three-phase to two-phase, and vice-versa, can be done using special circuitry with standard dual-wound transformers.

The phase-shift technique relies on using the harmonic currents produced by one load to cancel with the harmonic currents produced by a similar but phase-shifted load. Phase-shifting will therefore not work with a single harmonic producing load. Options for harmonic treatment include active filters, tuned filters, reactors, or moving the load to a dedicated feeder. Other treatments are possible.

Get out your wallet again! You need either a new motor and controls, or a phase converter. A phase converter does just what it says, it converts single phase power to three phase power. There are usually two types available, rotary phase converters and solid state or static phase converters. A rotary phase converter is simply an electric motor and a three phase generator connected by the same shaft. The motor turns the shaft and the generator produces the three phase current.

Yes, but because of how foreign motors are made, you will need to order a rotary phase converter that is one size larger than you would need for an American-built motor. For example, if you have a 2 HP Chinese or Taiwanese motor, you should order our 3 HP rotary phase converter. Foreign motors require greater amperage for start-up than American motors, so you would need a bigger converter.

The EOCR with Phase Reversal protection has provision for bypassing the Phase Reversal trip with DIP switch settings on the face of the EOCR.

Yes. SEECO is the leading supplier of electro-mechanical (non-hydraulic) motor operators for Turner switches. Our operators provide variable speed adjustment in both the opening and closing directions, easily field adjusted for normal open and fast slam close.

For rotary phase converters, the answer is a resounding "No!" Provided the converter is large enough, a rotary phase converter will develop the entire nameplate horsepower of the motor. You will have no power or capacity loss at all on a rotary phase converter. The same cannot be said for static converters, which generally do not allow motors to develop full horsepower. Static converters are unable to balance a current into three different legs.

Normally, machining operations have a built in cycle time when the machinist does an operation and then turns off the machine while a part is measured or changed. The advent of software generated 3D CNC programs that are thousands of lines long has brought a different type of use to Sherline machines, because some of these programs may take several hours to run.

If a barber or cosmetology shop, salon, or school only utilizes single-use manicure/pedicure instruments, then the sterilization requirement would not apply.

Most household electrical current is 240 volts, single phase. Industrial or commercial can be anything. If you aren't sure ask your electrical utility company or an electrician. It is important to know because it can be expensive to convert a kiln form one voltage to another. See complete technical information on voltage for more information. Not normally. You still use the same amount of KW hours regardless of the phase of the power.

Yes, provided that the motor HP does not exceed 15, and the job site voltage is 230 volt. The motors on these units are not currently Listed for fire protection, but the control panels on the fire pumps are. Cost increases are moderate.

Three-Phase Power - A type of power supply usually used for operating heavy loads. The three conductors of an HV system or (confusingly) the four conductors of an LV system (three live and a neutral). Kilo-Volt Amperes (KVA) - A measure of electrical power. The capacity of a supply is measured in KVA's. (KVA) - A measure of electrical power. The capacity of a supply is measured in KVA's.

Three-phase motors are less expensive than single-phase motors for motors of one horsepower or larger. Also, they are mechanically and electrically simpler than single-phase motors. This means they are more reliable. A three-phase system can use smaller wires and conduits than a single-phase system.

a. Normally this not a problem as long as the motor operates within the speed and current limits set by the manufacturer. Since motor speed is proportional to the voltage across the motor leads, select a power supply voltage that could not cause a mechanical over-speed in the event of an amplifier malfunction or a runaway condition.
