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:**

- Form a list of all items that will be powered.
- Determine the starting wattage (energy needed to turn it on) and running wattage (energy needed to operate it) for each piece of equipment. …
- 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.

## What size generator do I need to run a 5 hp motor?

Use of Engine Driven Generators – Single-Phase or Three-Phase

Motor Rating | Minimum Rating of Generator | |
---|---|---|

HP | KW | Internally Regulated |

5 | 3.7 |
9.4 |

7 1/2 | 5.5 | 12.5 |

10 | 7.5 | 18.75 |
