This means it doesn’t have brushes, as older motors do, that can wear out. That’s why these 5v-high-torque-dc-motor are so popular. They’re efficient, long-lasting, and need very little attention.
This engine uses magnets and electromagnets to move. The magnets in them rotate when powered externally, spinning the motor and producing energy. A 12V BLDC motor does not have brushes, which means friction gets cut and there is less heat as well. This can make the motor more efficient and reliable for a range of tasks.
12V BLDC motors can be found in robots, electric cars, air conditioning, and lots of home gadgets. Engineers and designers like them because of their small size and reliability.
Precise control over how fast and which direction a 12-volt-high-torque-gear-motor is necessary when it comes to many work. To accomplish this, the designer can employ a motor controller or driver. This part of the machine assists in controlling the amount of power that the motor receives.

A motor controller allows you to vary the speed and direction by adjusting the electrical signals the motor receives. You can easily control how the 6v-dc-motor operates by altering these signals.

But when 12V BLDC motors are laid out beside other types of motors brushed and stepper motors, for instance you will notice a few differences. Reasons to love a 12-volt-motor-high-torque-low-rpm great thing about a 12V BLDC motor is they are extremely efficient, and a long-lifespan for a couple of reasons mainly because it has no brushes to wear out.

Further, since 12-volt-worm-gear-motor move the smoother and provide better control over speed/direction than brushed and hence, you can't control brushed where and how you want. You can control the exact position with a stepper motor, but maybe it is not as efficient or reliable as 12V BLDC for a task.
