Are you considering purchasing a fan coil motor for your HVAC system but aren't sure which type is right for your needs? Look no further than this guide, where we break down the different types of fan coil motors available on the market today.


Fan coil motors are an essential component of any heating, ventilation, and air conditioning (HVAC) system. They work to circulate air throughout your building, keeping it at a comfortable temperature and ensuring proper air quality. But not all fan coil motors are created equal. There are several different types available, each with its own unique features and benefits.


In this guide, we'll take a closer look at the different types of fan coil motors available, so you can make an informed decision about which one is right for your needs.


Permanent Split Capacitor (PSC) Motors

One of the most common types of fan coil motors is the Permanent Split Capacitor (PSC) motor. These motors are simple, reliable, and cost-effective, making them a popular choice for many HVAC systems.


PSC motors use a single-speed design, which means they can only run at one speed. They're also not very energy-efficient, as they tend to draw a lot of power even when they're not running at full speed. However, PSC motors are easy to install and maintain, and they're a good choice for smaller HVAC systems or those with less demanding cooling requirements.


Electronically Commutated Motors (ECMs)

Electronically Commutated Motors (ECMs) are a more advanced type of fan coil motor. These motors are more energy-efficient than PSC motors, as they can vary their speed depending on the cooling requirements of your building.


ECMs are also quieter than PSC motors and produce less vibration, which can help to reduce noise levels in your building. They're also more durable than PSC motors, with a longer lifespan and lower maintenance requirements. However, ECMs are more expensive than PSC motors and may require a more complex installation process.


Three-Phase Motors

Three-Phase Motors are another type of fan coil motor commonly used in larger HVAC systems. These motors are highly efficient and can run at high speeds, making them ideal for cooling large buildings or commercial spaces.


Three-Phase Motors are also highly reliable and require minimal maintenance. However, they can be more expensive than other types of fan coil motors, and they require a more complex installation process.


Split-Phase Motors

Split-Phase Motors are similar to PSC motors but offer a bit more flexibility in terms of speed control. These motors can run at two speeds, allowing them to adjust their output depending on the cooling requirements of your building.


Split-Phase Motors are a good choice for HVAC systems with moderate cooling requirements. They're also relatively easy to install and maintain, making them a cost-effective choice for many building owners.


Shaded Pole Motors

Shaded Pole Motors are the simplest type of fan coil motor available. These motors use a single coil to produce a magnetic field, which drives the motor's rotor.

Shaded Pole Motors are not very energy-efficient and can only run at a single speed. They're also relatively noisy and produce a lot of vibration. However, they're a good choice for small HVAC systems or those with less demanding cooling requirements, as they're inexpensive and easy to install.


Brushless DC Motors

Brushless DC Motors are a more advanced type of fan coil motor that uses electronic commutation instead of brushes to control the motor's speed.

These motors are highly efficient and can vary their speed depending on the cooling requirements of your building. They're also very quiet and produce minimal vibration.
