Brushless DC Motors Vs Brushed DC Motors
There are many advantages of a brushless DC motor over a brushed DC motor. Almost every Platinum Gate Opener we carry features a state-of-the-art brushless DC motor. Thanks to the longer life of a brushless DC motor, these Platinum Access Gate Operators have some of the longest warranties in the industry - 10 years for residential and 8 years for commercial! Below you'll find many other advantages of a brushless motor over a brushed one.
Torque
Brushed DC motors are suitable for low-torque applications, while brushless DC motors are much more suitable for high-torque applications. With the same wattage motor, a DC brushless motor can drive a heavier gate than its brushed counterpart.
Speed
Brushed DC motors have a much lower speed range due to all the mechanical limitations of using brushes. Brushless DC motors, however, have a higher speed range due to there being none of the mechanical limitations that are imposed by both the brushes and the commutator.
Life
Brushed DC motors have a typical life expectancy of about 2,000 to 5,000 hours, depending on the application and duty cycle. Brushless DC motors have a typical life expectancy of 10,000 to 20,000 hours, double that of a brushed motor! This is why the brushless Platinum Access Gate Openers warranty is so long.
Efficiency
If you go with a brushless DC motor, you will get a high efficiency - up to 90%, compared to the lower efficiency of 60-70% in a brushed DC motor. If a gate operator with a brushless motor drives the same gate as a brushed motor, much less electrical power will be used. This saves more and more money over time, especially since the operator's life is longer.
Maintenance
In a brushed DC motor, periodic maintenance will be required; eventually, the brushes will have to be replaced. Brushless DC motors require little to no maintenance for the motor's life as there are no brushes or capacitors ever to replace.
Heat Dissipation
Brushless DC motors feature far superior thermal characteristics resulting in better heat dissipation than a brushed DC motor, where the rotor construction results in very limited heat dissipation.
Noise
Brushes emit a very audible noise during rotation. As you can guess, a brushless DC motor is much quieter because it's brushless!
As you can see, there are a ton of positives to choosing a gate operator that features a brushless DC motor over a brushed one. Questions? Our friendly sales team.
