You asked: Can I put a bigger motor on my generator?

If you put a larger engine on the generator, you would need to entirely replace the alternator with a larger one. The wiring inside would literally melt and short out if you tried to run double the power through your alternator.

What size generator do I need to run a 2.2 kW motor?

Single phase 2.2Kw motor : therefore the Generator will need to be 8.8kVA.

What size generator do I need for a 50 hp motor?

Rule of Thumb

Electric Motor Size Minimum Generator Req’d (KVA) by Starting Method
HP KW D.O.L to KVA Size (Note 1)
15 11 37.5
20 15 50
25 19.6 60.5

How many horsepower does it take to run a 10kW generator?

a 10kW alternator is likely to be roughly 85% efficient[1], so you need to be looking for around 11.8 kW on the input shaft. so 11.8/0.746 = 15.8 HP.

How do I increase the rpm of my generator?

Where f be frequency of the generated power from that alternator. Ns be synchronous speed. So, if we want to generate 50HZ frequency power from the 4-pole generator output then we have to rotate the alternator with the speed of Ns = (120*50)/4 = 1500 rpm or (1500/60) rps.

Why would a generator run but not produce electricity?

Loss of Residual Magnetism (Most Common)

Generators work by moving electrical conductors through a self-created magnetic field. However, generators do not contain any magnets. … However, if residual magnetism is lost, your generator will produce no power at startup.

What size generator do I need to run a motor?

Here’s a simple rule for estimating the size of an engine-generator set for motor starting: 1kW of generator set rating per each 3/4 to 1 hp of motor nameplate.

How do I calculate generator needs?

The basic generator sizing formula goes like this:

  1. Form a list of all items that will be powered.
  2. Determine the starting wattage (energy needed to turn it on) and running wattage (energy needed to operate it) for each piece of equipment. …
  3. Calculate your total power requirement by adding up these kW or KVA figures.

What size generator do I need for a 3 HP motor?

A generator rated 3 kVA will run a 3 hp motor. The engine that drives the generator may be rated 4 hp. If the motor load is hard starting, then you might need a larger generator, 4–5 kVA. Usually generators are rated in kilowatts, so a 3kW generator could be large enough, 4kW will work ok in most all cases.

Will a 12000 watt generator run a house?

Whole House: Starting at about 12,000 watts, these generators can generally keep a home running without missing a beat. You’ll be able to run lights, fans, TVs, refrigerators, computers, space heaters and pretty much anything else you plug into an outlet.
