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.
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.
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.
Ajax CNC -- Frequently Asked Questions
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!

Yes, however, if the load inertia is more than ten times the rotor inertia, cogging and extended ringing at the end of the move will be experienced.
Phase shifting transformer is used in certain systems to push more power in a specific line by introducing angle difference . The phase shift angle in the element data corresponds to the shift given to boost the power flow. Phase angle in the library is the phase shift introduced due to vector connection i.e. 1'O clock position or 11' O clock position etc. The Tie line refers to those lines connecting one utility to other or those lines, which island the system, when kept open.
SYSTEM BLOODCLOD - Radio Controlled Monster Trucks (RCMTs)
The number of turns of a motor is the number of times the wires in the motor are wound around the armature. 'Single', 'double', 'triple' and 'quad' refer to the number of strands of wires being wound onto the armatures. Single refers to one wire, double refers to two and so on Hence, a 16 turn double (16x2) breaks down to 2 wires being wound around the armature 16 times. The lower number of turns generally results in higher RPMs, amp draw and heat, as well as lower runtimes.
California Linear Devices, Inc.: Frequently Asked Questions
CLD motors are not designed to have an external side load applied. Any lateral loading of the bearings will increase wear of the bearings and reduce the life of the motor. Side loading of the shaft can also cause misalignment of CLD provided feedback devices.
DogLogic Great Dane FAQ's
quot;The Great Dane's personality is the quality that most find so appealing. The Dane is a "people dog" - a sensitive and affectionate companion. They can be elegant and dignified one moment, and then playful and silly the next." (Georgia Alyse Thomas) Danes are "leaners" and "blockers". This means that if there's a free lap, or an available foot, you'll usually find the resident Dane upon it.
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.
Roboteq Frequently Asked Questions
Yes. However, this requires a different wiring of the controller which must be set at the factory. This version of the controller is a special order. Price is the same as the standard version. Yes. Power will typically flow back into the battery during deceleration, or whenever the motor is spinning faster (because it is pushed, or inertia) than it would at the applied power level. Unfortunately not. Some of the energy is lost in heat inside the leads and the controller.
FREQUENTLY ASKED QUESTIONS FOR L&L CERAMIC KILNS
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.
Steven Brown Associates Sales and Service of fire pumps and ...
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.
California Linear Devices, Inc.: Frequently Asked Questions
The achievable peak frequency depends on the load mass and the amplitude. See AN-0140 for some guidelines in comparing motors for this type of use.
Frequently Asked Questions
This a difficult question to answer, because motor starting characteristics vary so much. Starting under load is also much harder, then starting with no load. We have successfully started many 2 h.p. motors in the past, but each application should be evaluated individually. We can start a 16,000 BTU air conditioner and after it is operational, we can start an additional 12,000 BTU unit.
The answer to these questions depend on the "stiffness" and capacity of your system. We can provide the right solution to ensure your motors will start without having to sacrifice system stability.
RV's To Go - Portland, Oregon
The motorhomes are equipped just as a normal truck or car, and you will find that they have a similar feel. The difficulties arise from the size of the vehicle compared to a normal vehicle. The height of the motorhome is up to 12 feet, which is considerably taller than most vehicles. In addition, the width of the motorhome is 8-1/2 feet, which is much wider than even a truck. The biggest challenge is the "tail swing" .
A-Aaron RV Rent, Indianapolis/Greenwood, IN - FAQ
We take the time to go over RV driving safety. Like anything new, you must orientate yourself to your RV. Stay focused. You are not driving a car or truck. It is different. If you elect we will take you on a test drive. In any RV you are driving a big box. All are long, wide and top heavy. In a Class A you are more conscious of the RV mass around you because your driver’s seat is at floor level and the road is more visible.
