Their most common uses include home appliances, home and business HVAC and other appliances such as drills, air conditioners and garage door opening and closing systems. This type of motor is used mainly in homes, offices, stores and small non-industrial companies. They are easy to repair and maintain, as well as affordable. They do not generate a rotating magnetic field they can only generate an alternate field, which means that they need a capacitor for startup. However, there are single-phase motors with a power of up to 10 hp that can work with connections of up to 440V. In most cases these are small motors with a limited torque. The circuit works with two wires and the current that runs across them is always the same.

They only have a single alternating voltage. Their power can reach 3Kw and supply voltages vary in unison. They contain two types of wiring : hot and neutral. It works by using a single-phase power supply.

Let’s get to it!Ī single-phase motor is an electrically-powered rotary machine that can turn electric energy into mechanical energy. If you are involved in a project and don’t know what type of motor you should use, this post will interest you! In it, we tell you about each motor and their differences. And choosing one or the other will depend on the necessary power. Depending on the number of supply phases, we can find single-phase, two-phase and three-phase motors with coiled startup winding and with coiled startup winding with a capacitor. Electric motors let us obtain mechanical energy in the simplest and most efficient manner.
