I was intrigued by BLDC DC motors when a friend first told me about them. They’re in so many things that we already see every day, like electric cars and robots!” I was curious to learn how these motors work, and why some people use them versus normal dc gear motor I chose this 12V DC motor because it contains an encoder that makes it possible to track how far it has turned in terms of pulses. I started doing a little research and discovered some pretty cool stuff
A BLDC DC motor uses a magnet to make the movement possible. Unlike conventional DC motors that use brushes, BLDC motors rely on electronic switches to allow current flow within the motor. This makes them cost-effective and time saving, which is the reason they are found throughout so many different applications.
There is one great benefit of using BLDC DC motors: they are more efficient compared to normal (brushed) mini dc motor. “It means they can save companies money on their energy bills and they can help reduce their carbon footprint. BLDC motors are also smaller and lighter than the classic DC motors, which makes them absolutely perfect for things like drones and electric bikes.
The thing that makes BLDC DC motors differ from typical DC motors is the way they are driven. Conventional dc electric motors also have the added disadvantage of requiring brushes to lead the electricity to the motor, brushes that will wear out over time. BLDC motors employ electronic switches, that makes them considerably more robust and durable. That’s why BLDC motors are frequently applied in environments where high reliability is essential such as medical equipment and industrial automation.
Speed and direction control of a BLDC DC motor is slightly different than that of a conventional DC motor. Position of the rotor is detected using sensors and the motor is then driven in the appropriate direction and with correct speed accordingly of the rotor. This enables finer control and improved performance for applications such as robotics and electric vehicles.
It’s the incredible jolt of energy we get from BLDC DC motors: they open up all kinds of new fields and applications. CDMs’ clients use BLDC motors in some pretty cool ways, ranging from automated assembly lines to robotic surgery to an airplane powered by an electric engine. Because they are so efficient and reliable, and can be controlled very precisely, BLDC drives are playing a major role in the development of automation and robots.
