Your garage door motor — it’s the beating heart of your garage door opener. But most people don’t know much about this garage door part. Whether you are looking to install a new garage door opener or replace an old motor, understanding this critical component is key. Here are 3 must know facts about garage door opener motors.
AC vs DC: The 2 Types of Garage Door Motors
Did you know there are 2 types of garage door opener motors? AC motors (alternating current) is the most common. These openers operate at the same speed when opening or closing the door. They can be a little noisier, but most people don’t notice the difference. DC motors use direct current. The main difference to DC motors is they regulate speed by starting slowly, speeding up, and then slowing down as the door reaches the ground. DC motors tend to be less noisy.
Motors Come in Different Horsepower
Whenever replacing a garage door motor, it’s important to choose a motor that has the right amount of power. Most AC motors have ⅓, ½, and ¾ HP. The force of DC motors however is measured in newtons — usually 500 or 700. That roughly equates to the ½ and ¾ AC models. Research the brand of garage door opener you own. Make sure you have a motor that has the right HP.
Longevity is Key
If you are buying a new garage door opener, it’s important to install one that will last. Quality matters. This will minimize any potential garage door opener repair problems. Try to choose a higher end model that has a life expectancy of 15 years or more. But it’s also important to know what you are paying for. Some higher end features are not always worth it.
