can we able to run 1hp,3phase generator,with input power from single phase 1hp motor?

Answer 1

No, because you cannot even reach synchronous speed with an induction motor. It would have to be belt-driven or have a gear box to reach sufficient speed, not to mention the drive losses.

Besides, what type generator will you use? A synch generator needs constant speed and a voltage regulator.

You could use a universal motor, i.e., the ones in blenders and vacuum cleaners, coupled to a 3-phase induction motor but you will need a speed regulator, and a capacitor bank to excite it and control the voltage. Too complicated.

The easiest thing would be to use a single to 3-phase static converter. You can get them cheap from ebay.com. I installed a 3HP one on a 5HP elevator motor. Works great.

Answer 2

One horsepower = 746 watts. A single phase 1hp motor will turn a shaft that may be connected to the shaft of a 1hp (746 watt) three-phase generator. If the generator is run without a load, the motor will run with a very small load. As the generator is loaded up the motor will take up the load. The load limit of the combination will likely be less than 746 watts due to less than 100% efficiency of the combination. The generator could even be wired to drive three unloaded single phase motors but the motor loads would have to be added in a balanced manner and each motor could be loaded to less than a third of the 746 watts power available from the prime mover. Single phase motors (in a home, etc.) are driven by a single phase of the two-phase power delivered to most homes which is supplied from the three-phase power system the power company supplies down most main streets.

Answer 3

If you link the motor to the generator with a driveshaft or drive belt it won't make any difference what the electrics of each are like, as long as the resistance in whatever the generator is powering isn't too great, and the speed of the motor is correct for the desired generator output.

Shouldn't the question be the other way round - can we run a single phase motor from a 3 phase generator?

If this was the case, the answer would be yes, as long as you couple the motor to only one of the phases from the generator, and as long as each phase is the right frequency and voltage for the motor. Depending on the type of generator, if you try coupling all 3 phases together without using a combiner such as a transformer, the frequencies of each phase may not match and so may, in effect, give a DC output of a different voltage.

Answer 4

A coworker a long time ago ran a 3 phase blower motor for a theater pipe organ with a device that was basically a capacitor. You connect the capacitor to one side of the single phase power and then connect the motor to the capacitor and the 2 sides of the power line. It is not perfect but it did work. I don't know how you size the capacitor except that you would want to be sure that the voltage rating was high enough. Can you contact the manufacturer of the lift to see if they know what to use? Edit: Check the reference.

Answer 5

If the question is for a single-phase motor driving a three-phase generator, the answer is you can. However, the generator may not be able to generate power to supply a 1hp load because of losses when transforming mechanical power to electric power. By the way, generators are not rated in hp; instead, they are rated in kVA or kW.

Answer 6

High power RF transmitters always run on 3 phase power. In remote locations where only single phase is available, they uses a "rotary" converter, which is what you propose. The are not particularly efficient, 80 to 85 percent is about the ratio of input to output power. This runs up the electric bill. The 15 to 20 percent waste creates heat. If you have to control the room heat with airconditioning, that will run up the electric bill even more.
