Los electric motors they allow us to obtain mechanical energy in a simpler and more efficient way. Depending on the number of power phases, we can find motors single-phase, biphasic, three-phase, with wind-wound auxiliary starter And with auxiliary starter with coil and condenser. And the choice of one engine or another will depend on the wattage necessary.

If you are immersed in a project and you don't know what type of engine you should use, this post interests you! In it we will explain to you what each consists of motor and their differences. Let's do it!

What is a single-phase motor

A single-phase motor is a rotary machine electrically powered, capable of transforming the electrical energy in mechanics.

It works through a single-phase power supply. In the wiring we can find two types of cables: one warm and one neutral. They have a power of up to 3Kw and the supply voltages vary in unison.

It has only one Alternating voltage. The circuit works with two wires and the current flowing through them is always the same.

In most cases these are engines of reduced size with a small power torque. However, there are single-phase motors, with a power of up to 10 hp that can operate with a connection of up to 440V.

They don't produce a rotating magnetic field, they can only create a Alternate field, so you need a capacitor to start.

And they are easy to repair and take care, in addition to affordable.

These types of engines are used mainly in homes, offices, stores and small businesses non-industrial. Among their uses The most common are household appliances, commercial and domestic refrigeration, ventilation, heating, and other utensils such as drills, air conditioning machines and parking door opening and closing systems.

What is a two-phase motor

A two-phase motor is a system of two voltages out of phase 90 degrees, which is no longer in use today. The alternator consists of two windings positioned 90 degrees relative to each other.

Require 2 power lines and one ground line that work in 2 phases. One increases the current to 240v for movement and the other maintains the fluidity of the current for motor use.

What is a three-phase motor

Three-phase motor It's a Electric machine that transforms electrical energy into mechanical energy by means of electromagnetic interactions. Some of the electric motors are reversible, they can transform mechanical energy into electrical energy working as generators.

They work through a source of three-phase power. They are driven by three alternating currents of the same frequency, which reach their maximum values alternately. They have a power of up to 300KW and speeds between 900 and 3600 RPM.

To be transmitted they are used 3-conductor lines, but for final use, 4-wire lines are used, which are the 3 phases and the neutral one.

Three-phase electrical energy is the most common method used by electrical networks all over the world because they transfer more power and it is widely used in the industrial sector.

Differences between single-phase and three-phase motors

First of all, we need to differentiate between the type of installation and current that circulates through this one. In this regard, the Difference between a single-phase and three-phase current consists in that single-phase current is transferred through a single path. In addition, having a single phase or alternating current, the Voltage does not vary.

Los single-phase motors are used when there is no three-phase system and/or for small powers, are generally used for powers less than 2 Kw or 3 Kw.

Los three-phase motors they are usually more used in the industry, since it has a power greater than 150% than a single-phase motor and generates a rotating magnetic field in three phases.

While the execution of a Single-phase motor can be noisy and vibrating, three-phase motors are more expensive, but they do not produce these vibrations and are less noisy.

In CLR we work daily with single-phase motors, designing and manufacturing reducers to get the perfect move. Among our success stories, the Deletion of mirrors in cars and commercial vehicles, capable of exceeding 50,000 cycles, 100% more cycles than those required at first by our customer Volkswagen.
