electric motors Let’s get mechanical energy in the simplest and most efficient way. Depending on Number of supply phaseswe can find single phase, two-phase and three-phase engines with rolled up starting winding and with wound starting winding with a capacitor. And the choice of one or the other depends on the needs energy.

If you are involved in a project and don’t know what type of motor to use, this post will interest you! In it we tell you about each one Engine- and their differences. Let us begin!

What is a single phase motor?

A single-phase motor is an electrically driven motor rotary machine that can turn electrical energy into mechanical energy.

It works with a single phase power supply. they include two types of wiring: hot and neutral. Your power can reach 3Kw and supply voltages vary in line.

You only have one single AC voltage. The circuit works with two wires and the current that flows through them is always the same.

single phase

In most cases these are small engines with a limited torque. However, there are single-phase motors with power up to 10 hp that can work with connections up to 440 V.

They don’t create a rotating magnetic field; they can only produce one alternative fieldwhich means they need a capacitor to start.

They are easy to repair and maintain as well payable.

This engine type is Second hand mainly inside Apartments, offices, shops and small not commercial companies. your most common Used This includes appliances, home and business HVAC, and other equipment such as drills, air conditioners, and garage door opening and closing systems.

What is a two phase motor?

A two-phase motor is a system that has two voltages that are 90 degrees apart, which is no longer used today. The alternator consists of two windings that are offset by 90 degrees from each other.

you need 2 live and one ground wire working in two phases. One boosts the current to 240V for motion, and the other maintains the ability to flow current for motor use.

What is a three-phase motor?

A three-phase motor is a electric machine which converts electrical energy into mechanical energy by means of electromagnetic interactions. Some electric motors are reversible – they can convert mechanical energy into electrical energy as generators.

You work with a three-phase current Source. They are powered by three alternating currents of the same frequency, which reach their climax in changing moments. You can have power up to 300KW and speeds between 900 and 3600 rpm.

Three tracks are used for transmission, but final use requires 4-wire cables corresponding to the 3 phases plus neutral.

Three phases

Three-phase current is the most common method in action at electrical networks around the world as it transmits more power and it sees significant use in the industrial area.

Differences between a single-phase motor and a three-phase motor

First we have to differentiate them Type of installation and electricity that flows through. In this regard, the Difference between single phase current and three phase current is that single-phase power is transmitted over a single line. In addition, since there is only one phase or alternating current, the voltage does not change.

single phase motors are used when a 3-phase system not available and/or for limited power – They are generally used for Outputs under 2 KW or 3 kilowatts.


three-phase motors frequently see more use in Industrysince their power is more than 150% greater than that of a single-phase motor, and a three-phase rotating magnetic field is generated.

When running a Single phase motor can be noisy and generate vibrationThree-phase motors are more expensive, but they don’t generate these vibrations and are less noisy.

at CLR we work with them every day single phase motorsdesign and manufacture speed reducer to achieve the perfect movement. Our success stories include a Folding system for side mirrors for cars and commercial vehicleswhich can exceed 50,000 cycles – 100% more cycles than originally requested by our customer, Volkswagen.
