How many watts does a sewing machine use

Due to COVID-19 and other economic crises worldwide, inflation has skyrocketed, due to which the majority of business owners are concerned. The same goes for sewists. Therefore they often ask, How many watts does a sewing machine use? 

Below, in this helpful guide, I will explain everything about wattage consumption, how to calculate it at home, and much more. So let’s start. 

Note: first, learn the difference between Ampere and Watt because this article will have these two terms a lot. 

Watts: it refers to the total amount of energy produced by electrical energy to run a machine.

Amps: It measures the amount of electrical energy flowing through an electrical line. 

That’s great; let’s get started!

How many watts does a sewing machine use?

“In short, a regular domestic sewing machine doesn’t consume too much electricity as it only consumes around 100 to 110 watts if only switched on; however, it will consume 145 watts if you start sewing”.

The wattage consumption of a sewing machine is not related to a single point but rather dozens of different factors, such as

  • Motor power
  • Usage duration
  • Fabrics Nature
  • LCD screen
  • Built-in features
  • LED light, if any
  • Number of stitches, etc

Be aware: Vintage or old-fashioned sewing machines consume more electricity than modern electronic sewing machines because they have clutch motors, which consume 70% more watts than motors found in modern sewing machines. 

Extra info: if you want to calculate watts, you must MULTIPLY Amps with Volts. For example, 1.2 Amps × 115 volts = 138 watts.

How to calculate electricity consumption per Hour of a sewing machine

Knowing the power consumption per Hour is essential for calculating the monthly consumption. 

A typical sewing machine consumes approximately 100 to 110 watts of power. 

Suppose you live in the US, where the approximate price of a UNIT is 0.16 USD, so here you use 0.10 watts in an hour“.

How much electricity does a sewing machine use per Hour?

Knowing the power consumption per Hour is essential for calculating the monthly consumption. A typical sewing machine consumes approximately 100 to 110 watts of power. Taking into account your physical location in the USA and a price of 0.16 per unit of electricity, you consume 0.10 watts per Hour.

You may ask, how did you find 0.10 watt? It’s done through a formula I’ll explain below.

But how? Let’s calculate…

How many watts does a sewing machine use

Two factors have to be taken into account when calculating the consumption of an electrical appliance in kWh (kilowatt-hours):

  • Watts: It shows the capacity of your electrical appliance. 
  • Usage time: This refers to the amount of time spent using your sewing machine, it can be expressed in seconds, minutes, or hours, but for universal formulas, you should use HOUR

a) Putting the values

Let’s suppose I use a sewing machine for 24 hours, and its wattage capacity is 100, and the electricity price in the USA is 0.16 USD per unit.

b) Let’s see the wattage consumption

The following is the result for an hour, a day, a week, a month, and a year.

How to locate the watt number of my sewing machine?

Following these steps to locate within a few seconds:

  • First, check the user’s manual of your sewing machine; you will probably find it, but in a few cases, you need to do something else. (Optional Step)
  • The best method is checking the BACKSIDE of your sewing machine, where there will be a STICKER (as shown in the pic below) that indicates the wattage of your machine. (The Easiest Option) 

Types of sewing machines based on Watts consumption

1) Industrial Sewing Machine

  • Industrial sewing machines use more electricity than any other machines because they are intended to be used for the mass production of fabrics. 
  • Consequently, industrial sewing machines consume around 180 and 280 watts of electricity depending on the power of their motor. 
  • However, different industrial models, such as double needle lockstitch sewing machines and other high-end ones, consume 430 watts.

2) Handheld sewing machine or mini sewing machines

  • Handhelds are the smallest among all other types of sewing machines and consume around 20 and 50 watts. 
  • Their work is also less demanding as they are used only for small sewing cuffs, etc.

3) Brother Sewing Machine wattage consumption

  • Brother manufacturers advanced and user-friendly machines with less watt consumption of around 75 to 100 watts, depending on their model and capabilities. 
  • A typical sewing machine from Brother consumes 70% less electricity than other heavy-duty machines.

4) Singer sewing machine use

  • In today’s sewing world, Singer sewing machines are also considered king. They are too effective and come with a top-of-the-line motor. 
  • Let’s assume that your Singer sewing machine has an ampere number of 0.7 amps and that you reside in the USA, where the voltage is 120 volts. The result of multiplying 0.7 amps by 120 volts is 84 watts, a very efficient number.

5) Juki Sewing Machine wattage consumption

  • The typical Juki sewing machine consumes approximately 110 watts, which makes it no different from Brother and Singer sewing machines. 
  • However, the Juki Semi-Electrical Industrial Sewing Machine consumes 300 watts due to its high power output.

6) Hand-powered sewing machine

  • Electricity will not be consumed by anything that does not use electricity. Does that make sense to you? Let me explain in more detail. 
  • In addition to electric sewing machines, manual sewing machines are operated by hand without electricity. 
  • These machines are often referred to as treadle sewing machines since they are vintage models that are highly durable and reliable.

Long story short, vintage treadle sewing machines do not require electricity; they are operated manually and do not consume electricity.

Does my domestic sewing machine use a lot of electricity?

Unlike industrial sewing machines, regular household machines consume a decent amount of electricity everyone can afford. 

As mentioned above, a typical sewing machine will consume around 100 to 110, showing that you are safe. 

Moreover, if your sewing machine has an LED light bulb, it may consume an extra 10 watts, nothing more. But it is when your machine has this feature.

For example: If you use a 100W sewing machine for 30 complete days, you are using 2.4KWH per day. In one month, the consumption cost will be (2.4kWh x 30 days x 0.16 $/kWh) = $11.52. So $11 is a small amount, even for those who live in an expensive apartment with a rent of around $2000 ( in NEW YORK).  

Note: It is explained in the above heading completely with the formula and screenshots.


Frequently Asked Questions

Q1. How many watts is my sewing machine motor?

Ans: An electric motor drives the sewing machine, and a domestic sewing machine generally has a motor with a power rating of 40 to 50 watts. However, adding electric bulbs and other electric devices to these machines may consume approximately 110 watts in total.

Q2. Can I power my sewing machine with an inverter?

Ans: An essential characteristic of an inverter is that it makes work easier and faster while supplying electricity on a regular basis.

Q3. Can I operate a sewing machine with solar energy?

Ans: Solar energy can make your sewing machine extremely powerful and makes it work better for you. In addition, you should attach a permanent magnet DC motor since this motor increases the efficiency of the sewing machine by 25% by making it compatible with solar power.

Q4. Do all sewing machines consume the same amount of electricity?

Ans: No, it depends upon the brands, types, and models of different sewing machines. Like a typical Brother sewing machine 75 to 100 watts, Singer machines may consume approximately 85 to 100 watts, etc.
