Understanding Horsepower for an Automatic Garage Door Opener in Novi, MI

by | Mar 26, 2020 | Garage Doors

As someone looks over specifications for a new garage door opener in Novi, MI, the level of horsepower will be included. The concept may seem intuitive when connected with a vehicle’s motor since these large animals commonly pulled buggies and wagons before engines were invented. How does horsepower relate to a garage door opener?

A Brief History

The formula for how much power a motor provides is related to how much work a horse can accomplish when doing a specific task. This formula was devised in the late 1700s by James Watt, the inventor of an improved model of the steam engine. The mathematics allowed everyone to easily understand how much horsepower the engine could provide. This is the same calculation applied to the motor of a garage door opener in Novi, MI.

Garage Door Openers

When professional contractors install a garage door opener, they evaluate the doors and the entire system before deciding on the necessary horsepower and other features. Most openers are between 1/2 to 1 horsepower. One unit of horsepower equals 746 watts. Openers providing 1/3 horsepower can lift lighter-weight doors. That includes single doors and those made of lightweight aluminum or uninsulated steel.


In comparison, the horsepower of a 2020 Ford Mustang ranges from 310 to 480. The power of an average household blender is approximately the same as an automatic garage door opener, although the most expensive models have about twice that much.
