How Does a Variable Speed Motor Work?

There are a few different kinds of furnaces available to you. One of those furnaces is a variable speed furnace. There are some benefits to a variable speed furnace. Two of the benefits is that they are quieter and they are more energy efficient. Normal furnaces tend to run at top speed the whole time they are operating which takes more energy. The variable speed motor runs in two stages which is more energy efficient and it distributes heat more evenly. The variable speed furnace uses and ECM to control the motor speed. ECM stands for electronically commuted motor. The normal motors use alternating current while a variable speed motor uses direct current. An inverter in the variable speed motor converts the alternating current to direct current which is way more efficient. The variable speed motor has more components inside that can detect just how much heat the home needs and runs the motors accordingly. If you only need a little more heat then the motor runs slowly and if more is needed then the motor runs faster. The variable speed also compensates for obstructed areas like dirty filters and blocked returns. Another advantage to using a variable speed motor is the cleaner air due to the fact that the slower motor takes more particulates out of the air. One last advantage to using a variable speed motor furnace is the durability that comes with it. The fact that it has multiple speeds introduces way less wear and tear on it so it lasts way longer.
